Bear Glass NJ Acid Etched Glass is becoming trendy in design and construction.  The consistency and durability of the finish can reduce glare and reflection, add privacy, increase light transmission, and provide texture.  It is important to select the right acid-etched glass for an application, and avoid making issues during storage and fabrication.  Although the glass-etching process is generally consistent, variations in chemistry and other parameters create different surfaces with distinct visual and performance characteristics.  Glass is etched with an aqueous solution of hydrofluoric acid, which attacks the silica and roughens the glass surface.  Generally, the more ‘white’ or opaque the finish, the more rough and porous the surface is.  When choosing distinctive and unique types of glass, architects and designers often have specific objectives in mind.  With acid-etched glass, these goals can relate to light diffusion, light transmission, privacy, visual appearance, integration with surrounding objects, and energy efficiency through increased day lighting.  An etched surface with rugged peaks and deep valleys absorbs and diffuses light, rather than transmitting or reflecting it- the result is a rich, white, opaque appearance.  In contrast, an etched surface with smooth, rounded bumps enhances light transmission and creates a more transparent glass, characterized by reduced reflective glare and a soft translucent appearance.

Acid-etched Surface Finish

Acid-etched finished vary by manufacturer.  The type selected for a glass substrate renders a different level of opacity and smoothness and creates varied visual effects.  It also impacts performance ratios such as gloss, visible light transmission (VLT), visible light reflectance, shading coefficient, solar direct transmission, solar direct reflectance, and U-value.  The visual effect of the acid-etch finish on mirror varies depending on the extent of etching performed.  A lighter-etched mirror has more reflection whereas a deeper etch creates a matte finish and more depth in the glass.

Glass Substrate

The substrate also influences the color appearance, level of opacity, and performance ratios of acid-etched glass.  Many falsely believe pieces of ultra-clear glass look the same, irrespective of their origin; similarly, glass with a blue tint from manufacturer ABC is often incorrectly perceived to match the one produced by manufacturer XYZ.  Generally, the glass business markets different shades of glass in ultra-clear, green, blue, or black.  In addition, some glass floaters can make varying shades of one color.  For example, acid-etched products manufactured from low-iron glass have a translucent satin appearance without the ‘greening effect’ of ordinary clear glass.  Similarly, a piece of acid-etched glass made with a dark blue hue from one supplier creates a different visual effect than one made with light blue from the same manufacturer.  Consequently, the shade of the acid-etched glass or mirror likely varies among manufacturers, depending on the substrate used.  It is important to remember the acid-etched finish itself creates a different color appearance, with different tints having varying performance ratios.

Etching on both sides

Etching glass on both sides can enhance its characteristics.  This approach is suitable for applications requiring a higher level of opacity or a similar finish and visual effect on both sides of the glass panel (e.g. partitions).  Most glass is produced by the float process.  The raw materials- mainly silica sand, soda ash, and limestone- are melted in a furnace and then flowed onto a bath of molten tin.  The glass then takes form and gradually cools as it moves from the tin bath to a controlled cooling chamber.  Float glass is best etched on the ‘air’ or ‘atmosphere’ side of the sheet, due to the greater likelihood of impurities and surface imperfections on the ‘tin’ side.  Production of acid-etched mirrors and two-sided etched glass requires etching of the tin side, posing an increased risk of defects in the surface if inappropriately done.   When considering double-sided acid-etched glass or acid-etched mirror, the type of finish specified impacts quality.  The manufacturer of the acid-etched product can recommend the finish (if any) suitable for the application.

Exterior applications

Bear Glass New Jersey Acid Etched Glass may be appropriate for exterior applications, such as insulated glazing (IG) units, skylights, and balustrades.  As acid-etching is not a coating, its resistance properties in outside conditions are essentially equivalent to non-etched glass.  However, it is important to note an etched surface with rugged peaks and deep valleys could lead to higher maintenance costs because dirt particles may be harder to remove.  Therefore, the use on an etched surface with a lighter finish (i.e. smooth, rounded bumps) is recommended in exterior applications.  In these situations, the level and type of maintenance required is similar to that of non-etched glass.

Storage and Fabrication

If proper care is taken during storage and fabrication, acid-etched glass or mirror can be kept clean as easily as non-etched products.  Whether the glass is tempered, laminated, insulated, painted, or even bent, fabricators can preserve the quality of the final product.  However, the general suggestions for keeping acid-etched glass or mirror stain-free during storage and fabrication may not be suitable in all situations.  Fabricators should follow guidelines issued by the manufacturer of a particular product to prevent or fix any marks or stains that occur.

Storage

Proper storage practices can help avoid marking on acid-etched glass and mirror.  Storage spaces must be dry and adequately ventilated.  Sheets should not be stored in areas of high humidity or heat (e.g. places near steam or water pipes).  Spaces exposed to chemical fumes should also be avoided.  All these conditions promote staining.  Conversely, sheets should not be stored outdoors or in unheated areas.

Fabrication

Due to the particular characteristics of more rugged glass surfaces, extra care should be taken during their fabrication to minimize the likelihood of embedding grease or dirt into the surface.  Gloves must always be used when working with sheets.  When handling sheets using equipment with suction cups, the clean and dust-free cups should be applied to the flat, untreated side.  If this is impossible, care should be taken to ensure proper vacuum is achieved (i.e. testing must be done to be certain the cups ‘stick’ to the glass to handle to weight).  When edging glass, these practices should be followed:

1. The edging machine conveyors should be clean and free of grease and buildup of glass grindings or cerium oxide.
2. The conveyor must be regularly opened and the machine interior washed (particularly the brushes) using soapy water.
3. The front and back conveyor pads should be routinely brushed, until all traces of cerium oxide and glass grindings are removed.
4. The front and back conveyors must be synchronized at identical speeds.
5. Only coolants specifically recommended for glass grinding and that adhere closely to the manufacturer’s recommended dilution ration should be used.
6. Manufacturer guidelines for concentration levels must be followed when using cerium oxide, with care taken to never add more than the minimal amount necessary for good polishing.
7. Glass should be washed immediately after polishing.  Washer brushers with .36-mm (0.014-in) diameter nylon bristles offer the best results.  The glass washer should be equipped with one pair of upper and lower brushes for every 0.6m (2ft) per minute of travel- for example, a machine operating as a speed of 1.8m (6ft) per minute should have three pairs of brushes.  (This guideline is only applicable to regular float glass and not to coated products such as low-emissivity [low-e] glass).
8. As an extra precaution, wetting the glass surface immediately before polishing greatly reduces the risk of marking.

Writing the Right Specifications

Architects and designers constantly look to Bear Glass for new ways to use glass in exterior and interior applications.  Writing proper specifications, especially when distinctive and unique types of glass are chosen, is critical to ensure the desired design is achieved.  Acid-etched glass is no exception.  If care is not taken, the glass ordered and installed on the jobsite may be nothing like the product selected based on samples submitted.  To ensure the acid-etched glass products selected are actually used by the general contractor, glass fabricator, and glazier, the following information should be included in the specifications: name of manufacturer, product brand name, glass thickness, substrate (glass or mirror), tint (e.g. clear, ultra-clear, blue, green, black, bronze, grey), type of finish (name), and whether to etch on one or two glass faces.  Warranties and standards are often overlooked when writing specifications.  Inherent in the float glass process are small gaseous inclusions and minor abrasions.  Consequently, occasional, small ‘bubbles’ and hairlines are normal and acceptable under recognized standards; from a normal viewing distance, they are barely noticeable.  To ensure acid-etched products are made from float glass that conforms to industry standards, the manufacturer should be consulted.  In Canada, glass should comply with Canadian General Standards Board (CAN/CSBG) 12.3-M91, Flat, Clear Float Glass (Quality: Glazing).  In the United States, ASTM International C 1036-01, Standard Specification for Flat Glass (Quality: Q3-Stock Sheet) should be followed.  The manufacturer’s product warranty should refer to these standards.  Clearly, it is important to be specific about the nature of the acid-etched glass product required.  Communicating specifications in detail to a glass professional can help ensure the chosen product meets desired goals and objectives.

Resin Stained Glass is one of the new processes by Bear Glass when you can lay down just any design you want on the glass in variety of colors. The resin is applied to the outer layer of glass, using a stained resin machine. Bear Glass applies the resin also to mirrored glass. Traditional handcrafted Resin Stained Glass by Bear Glass has long been recognized for its beauty and dazzling visual impact.

Bear Glass does not use any lead strips in the process of making the Resin Stained Glass but instead uses UV stable, colorfast acrylic resins. The acrylic resin is extremely durable and one can easily compare it with a toughened glass.

Bear Glass can do a whole range of standard Resin Stained Glass designs, still we believe on the visions of our customers. Resin Stained Glass by Bear Glass can really transform a dull back door piece of glass or be used to make a big centerpiece in a landing or hallway. Bear Glass creates beautiful Resin Stained Glass for door panels, windows, fanlights, mirrors etc. The choice of design, color and texture is extensive.

Bear Glass can make faceted glass windows with Resin Stained Glass. Bear Glass artisans use one inch (2.5 cm) thick slabs of glass, cut into the desired shapes then selectively faceted on the interior edges to enhance the refraction of light. Then an epoxy resin is poured between each piece to create the structural matrix. Finally, the resin is covered with a layer of colored granules.

Bear Glass combines the resin stain with silk screening and glass grooving to create even more texture and depth in your design. For came colors you aren’t limited as you are with traditional leaded beveled glass designs.  With Resin Stained glass by Bear Glass you can have red, white, taupe, gun metal, just about any color you want.

One thing to note here is that Resin Stained Glass isn’t a good choice if one just needs a handful of pieces. But for doing multiple pieces this is a beautiful solution for unlimited design capabilities.

One big difference between the Resin Stained Glass and traditional decorative leaded beveled glass is, you can make dual IG units out of them as the Resin stain is applied to tempered glass also.

The advantages of Resin Stained Glass by Bear Glass are:

• Unlimited Design Possibilities: Any design that can be drawn on paper can be reproduced as a stained glass pattern.
• Cost effective: One-half to two-thirds the cost of traditional stained glass, even for one-off designs.
• Energy efficiency: The stained glass pattern can be put directly on modern double or triple paned glass, even on glass that is in a manufactured window sash.
• Cost effective custom work: Computer design and modern manufacturing techniques keep the cost on custom work to about one half the cost of traditional stained glass.
• High volume production runs feasible: The robotic CNC resin dispensing table enables high volume runs with excellent accuracy and reproducibility for every piece.

Bear Glass ships their Resin Stained Glass products worldwide. We do everything on glass.

Are you looking for woodstove glass replacement? Bear Glass can offer super heat resistant neoceram that is the perfect solution for use as cast iron wood stove glass doors where the panels are less than 6 inches from the hot burning fire.

The glass in your wood stove door or fireplace gives you a clear view of the fire burining. This is part of the ambiance of having a wood stove or fireplace. When you have glass in the wood stove door, it makes it that much more enjoyable to have a fire burning on a chilly fall evening or a cold winter day. Sometimes, due to accidents, the wood stove glass gets broken. We can replace it for you. We custom cut the woodstove glass to meet your needs. If it is curved or any shape other than a rectangle, provide us with a template and we’ll cut it to your specifications. Bear Glass specializes in 24 hour turn-around so you have your wood stove glass back in your woodstove door and you are back in service, once again enjoying a romatic fire on a chilly evening.

Neoceram® is commonly referred to as glass but it is actually a transparent ceramic. Neoceram is 3/16″ or 5mm thick. Unlike true glass, NeoCeram® withstands continuous exposure to high temperatures without fear of destruction. It is also resistant to failure due to temperature variation. This makes it the ideal solution for many wood stoves and fireplaces where glass panels are less than 6 inches from the flames. We offer optional tints or colors for your custom order.

Neoceram is a transparent low expansion glass-ceramic with a number of outstanding features that include high resistance to thermal shock, high mechanical strength, and excellent electrical characteristics. With an almost zero thermal expansion coefficient, the applications for Neoceram continue to grow from Wood Stoves, Gas Fireplaces, Electric Heaters to High Tech Applications.

About Neoceram Neoceram is commonly referred to as glass but it is actually a transparent ceramic. Neoceram is 3/16″ or 5mm thick. Ideal Solution for Woodstoves. Unlike annealed glass (Regular Float), Neoceram withstands continuous exposure to high temperatures without the fear of destruction. It is also resistant to failure due to temperature variation. It is the ideal solution for many wood stoves and fireplaces where glass panels are less than 6 inches from the flames.

Strength and Durability Neoceram can take the heat! Continuous temperatures up to 1470°F (700°C) can be withstood because this ceramic has an extremely low thermal coefficient of expansion. It doesn’t run or swell at high temperatures the way normal glass does.

Field Tested against Underwriters Laboratories (UL-1482) impact test Neoceram is a glass product that offers continuous, high temperature use (700°C / 1470° F) with no fear of destruction from high heat or temperature variation (water or snow on hot glass). Whether burning gas or wood, today’s high efficiency stoves and fireplaces can produce intense heat. While ordinary tempered glass withstands temperatures up to approximately 250° C (500°F), higher levels of heat may cause it to crack and shatter or worse explode out of your fireplace. For builders and home owners, that can mean costly replacements – or worse!

Thanks to modern technology, there is now an alternative! With the transparency of glass and the heat-resistant characteristics of ceramic. Neoceram can tolerate continuous temperatures up to 1470° F – nearly three times the heat resistance of tempered glass. Neoceram cannot be broken by heat during typical usage in a wood stove or gas fireplace.

Bear Glass has the answers you are looking for regarding wire glass.  Wire glass is used in fire-rated windows and doors because it meets most fire codes. It is made by feeding a welded wire net into the molten glass before it enters the rollers. The wire does not add strength to the glass, but it does hold the glass in the sash if it shatters.

The process of wire glass, or wired glass, is sheet glass in which wire mesh has been inserted during production. The impact resistance of this glass is similar to that of normal glass, but in case of breakage, the mesh retains the pieces of glass. This product used to be accepted as low-cost fire glass but is no longer acceptable for this use. Now, wire glass is mostly used for windows because of it exceptional security qualities. Clear wire glass and obscure wire glass is available at Bear Glass.

Wire glass is a common sight in schools, businesses, and hotels across the nation. Wire glass is manufactured primarily as a fire retardant, with wire mesh inlaid in the glass to prevent it from shattering and breaking out under stress or when exposed to high temperatures. With the window intact, the wire glass keeps the fire at bay, protecting those on the other side from the harmful effects of smoke and flame.

Wire glass typically comes in two types — Misco and boxed. Misco is also called diamond wire glass. In boxed wire glass, the wire is rotated 45-degrees, so that it makes s a checkerboard pattern, rather than diamonds.

There are pros and cons of installing wire glass.

There are many myths about wire glass and its proper usage. Primarily, most people assume that that the incorporation of wire into the glass makes it stronger, and that this makes it a good option for security glass. Actually, the wire in the glass actually weakens the wire glass from a strength standpoint, and makes it more susceptible to breaking. What the wire does do for the glass is hold it in place. That makes it safer from the standpoint that a broken window won’t send glass fragments showering through a room (hence its use in schools), and that the wire will hold the glass in place under extreme temperatures (hence its status as fire rated glass).

Wire glass is a smart addition in any area where a solid fire barrier and safety glass are beneficial. This includes using wire glass in public areas such as schools, public buildings, and businesses, and particularly in areas of these buildings that provide escape routes in case of fire. Windows in stairwells and in hallways that lead to emergency exits are prime examples of areas where fire rated wire glass is a smart addition.

Bear Glass specializes and is a leader in low iron glass.

Low iron glass is ultra clear and provides a higher degree of transparency compared to clear float glass. This optimum clarity is achieved by removing most of the iron oxide content used to produce glass.

The virtual absence of color makes low iron glass the natural choice when neutral color and clarity count.

Low iron glass belongs to a group of extremely clear glass with minimal green cast. High light transmission and brilliant surfaces make this glass ideal for colored glass applications, frame-less glass installations such as shower doors, glass doors and glass table tops. Low iron glass utilizes a raw material formula that increases light transmission and neutrality while reducing the greenish tint in clear glass that is most apparent when viewed from the edge. The result is pure, sparkling and very clear glass.

Low Iron glass is a high quality and ultra clear float glass, also called extra clear glass. The transparency of low iron glass can reach 91%. Low iron glass also can be done different deep processes same as float glass, such as, tempered, curved, laminated, insulated, and so on. Low Iron glass is mainly used for photo electricity conversion, solar energy, top-grade buildings, decorative glass, top-grade furniture, imitating crystal product, special type buildings, and so on.

Bear Glass can assist you in using low iron glass for your decorative needs throughout your home or any commercial building.

Properties of low iron glass include high clarity and transparency, low iron oxide content, and not green tint that is inherent in normal float glass.

One of the most prominent places that low iron glass is useful is in glass shower doors.  Bear Glass has a wide range of variety in the field of low iron glass for this usage.

Another usage of low iron glass is with energy based applications.  Solar panels are ideal for this type of glass.  The ultra pure sunlight that can be used by low iron glass is above all others for this necessity.

More and more uses for low iron glass are constantly trending.  One of the biggest right now is low iron glass used for aquariums and all types of fish tanks.  This is due to low iron glass being extremely clear and transparent.

Bear Glass recommends using low iron glass for other applications such as shelving, laminated glass, greenhouses, tabletops, furniture, decorative glass, and appliances.

When you think of fire protection in a building, what comes to mind? Fire extinguishers? Smoke alarms? Sprinkler systems? Chances are that window glass wasn’t at the top of the list. While fire-rated glass has been an important component in building safety for decades, most professionals in the industry know relatively little about it. As a result, it isn’t difficult for the incorrect product to be specified, installed and approved – potentially putting lives and property at unnecessary risk.

We’ll begin with some basic definitions. Just what is fire-rated glass? As the name implies, it is glass that has proven to offer a certain degree of protection in the face of fire. That may sound like a strange task for glass to perform. Obviously, glass can’t extinguish a fire or warn a building’s occupants that there’s any danger. But fire-rated glass can help keep flames and smoke from spreading from one room to another. The official term for this is compartmentation, and it means that glass can play a vital role in restricting fire damage to a limited area.

To the casual observer, it would seem that any glass could do that. After all, fire-rated glass looks deceptively similar to its non-rated counterparts. However, in reality, most glass offers little, if any, fire protection. For instance, standard window glass will break when the temperature reaches approximately 250° F. Tempered glass can last until about 500°F. In contrast, fire-rated glass can typically survive heat in excess of 1600° F. That’s a marked difference in performance. With structural fires capable of reaching extremely high temperatures very quickly, the need for this specialty glass is easy to recognize.

To earn its stripes, fire-rated glass must pass a battery of tests established by national test standards. Independent laboratories (such as U.L.) run the tests, then assign an appropriate rating based on the results. The ratings are time increments, reflecting the duration of testing the product endured. That duration is intended to correspond to the length of time the glass should be expected to perform reliably in a fire. So if a product has a 45 minute rating, theoretically you could count on it containing flames and smoke for the first 45 minutes of a fire.

The testing is conducted in two parts. First, several pieces of the glass are installed in the wall of a large furnace. The wall might contain doors, sidelites, transoms, windows, etc. Following a strict time/temperature curve, the heat in the furnace is raised to an intense level, simulating conditions in a burning building. In order to successfully pass the test, the glass must remain in the frame. Cracking is allowed, provided the glass can still act as a barrier to flames and smoke.

Assuming the glass survived that portion of the test, there is a second phase required in the U.S. for a rating of 45 minutes or more. This is called the hose stream test, and it demonstrates the ability of the glass to withstand what is know as thermal shock. A fire hose with a high pressure nozzle is brought in to douse the hot glass with water at a pressure of at least 30 psi. Most glass cannot tolerate the stress of having one area hot and the other cool at the same time, and so it will shatter. If sprinklers come on during a fire, or if fire fighters arrive with extinguishers and hoses, it is quite possible for hot glass to be exposed to water. The last thing anyone would want at that point would be for the glass to vacate an opening, leaving room for the flames and smoke to spread. The hose stream test thus tests the integrity of the glass, framing system, and surrounding materials.

Once a product has completed the rigorous test process, it is assigned a fire rating. Ratings generally run anywhere from 20 minutes to 3 hours. Building codes then dictate where those differently rated products would be allowed in a building. In general, the codes are designed to take into account how long it will take people to exit a building in the event of a fire.

As you might suspect, many of the locations (such as doors and sidelites) requiring fire-rated glass are also locations where impact safety is a concern. This used to pose a real dilemma, because product options were very limited. None of the glass that had high impact ratings could pass the fire tests, and the fire-rated glass (typically wired glass) wasn’t strong enough for more than the minimum impact testing. So there often had to be a compromise. Today, however, there are several wireless glass products available that offer high levels of both fire and impact safety.

Impact ratings indicate what can be expected if someone (or something) runs into the glass. To test for impact, a 100 lb. bag of lead shot is dropped against a vertical piece of glass. The bag is raised to various heights for the different ratings to approximate the impact of individuals coming in contact with the glass. Afterwards, the breakage pattern of the glass is closely examined to determine whether or not it would be considered a hazard.

If you see a piece of wired glass with a label that says ANSI Z97.1, that means the glass has been tested to withstand 100 ft./lb., similar to impact of a small child. On the other hand, glass labeled as meeting CPSC 16CFR1201 (Category II) withstands 400 ft./lb. That is similar to the impact of a fast moving, full-grown adult.

When you multiply the number of fire ratings with the different safety ratings, you can see that the possible combinations are impressive. But ratings alone do not distinguish the various types of fire-rated glass on the market today. Each product has its own unique characteristics, making the decision process even more complex.

Despite all the variety, the field can be organized in a fairly simple and logical way. All fire-rated glazing falls into the following four primary categories:

Bear Glass Polished Wired Glass is far and away the most well known product in the industry. Used for more than a century, it has a solid track record. Most codes were originally written around wired glass, because for many years it was the only glass that could pass the fire testing. Wired glass is able to pass the hose stream test, and has earned a 45 minute rating (even higher in very small door sizes). Code and fire officials have been able to instantly recognize the wire mesh as a sign that glass was fire-rated.

In some instances, however, that same wire mesh has presented an undesirable “institutional” image. And occasionally, people have mistakenly assumed that the wire mesh makes the glass more impact resistant. Truth be told, wired glass is a relatively weak glass that only meets minimal 100 ft./lb. impact standards. With that in mind, even though wired glass is readily available and easily affordable, great care should be taken if it is installed in areas where impact safety is a concern, such as schools and other high traffic areas. Some schools, with liability issues in mind, use high impact fire-rated glass – even if initial costs are higher.

Bear Glass Ceramic Glass is a category of fire-rated glazing that has entered the market during the past 12 years. Ceramic has long been known for its amazing ability to withstand heat and thermal shock. That’s why today you can find ceramic in everything from cooktops to car engines. Once the technology was developed to form a clear product out of ceramic, it didn’t take long to see the potential for its use as a fire-rated glass.

Bear Glass Transparent and Wireless, Ceramic Glass offers a distinct aesthetic advantage. It comes in a range of make-ups that can provide many different characteristics: fire ratings up to 3 hours, high impact safety ratings, sound reduction, etc. It can also be beveled, etched or sandblasted without affecting the fire rating. It is even available in insulated glass unit (IGU) make-ups that comply with energy codes for use in exterior applications.

Bear Glass Specialty Tempered Glass has become a popular alternative for low level fire safety. It is clear, wireless and has a fairly moderate initial investment. High impact ratings make it suitable for some door applications. However, it does have some serious drawbacks that are important to note.

Unlike other fire-rated glazing products, specially tempered glass doesn’t pass the hose stream test. In an actual fire, if sprinklers activate nearby and even a small amount of water hits the hot glass, it will likely fall out of its frame – quite possibly within just a few minutes. That’s why it has only been able to comply with standards for a 20 minute rating. Many times this type of material has been inappropriately substituted for wired glass or other higher performance fire-rated glass, when in fact it does not carry the same fire rating. If sprinklers are anywhere near the opening, this product should not be considered.

Bear Glass Transparent Wall Units make up the final category of fire-rated glass, and in reality, they are in a class by themselves. They are tested and classified as “walls, ” even though they are made of glass. Their claim to fame is their resistance to heat tranfer. Transparent wall units can actually block significant amounts of heat from transfering through the glass. A fire could be raging on one side and you could literally still place your hand on the other side of the glass. For areas such as stairwells where people could be trapped for long periods of time, or in sensitive computer areas, or where large expanses of glass are used, transparent wall panels serve a genuine need.

There are different kinds of these products on the market. Some are insulated units filled with a clear gel that turns to an opaque foam during a fire. Others are made of multiple layers of glass (similar to bullet resistant glass) with intumescent interlayers that turn opaque during a fire. Both styles of products have ratings of up to 2 hours, withstand the fire hose stream test and offer high impact safety ratings. Thanks to new framing that is now available, architects can incorporate these transparent wall and door units from floor to ceiling in their designs, and still offer 2 hour fire protection.
