Anemostat Door Glazing Resource Guide, 20 pages (2013)

Teach me about Glazing

Glazing can be categorized into three major groupings:

1. Fire-Rated Only (walls, transoms, borrowed lights)

2. Safety/Impact Rated Only (non-fire rated doors and other hazardous or security applications)

3. Fire and Safety Rated (fire rated doors or any application deemed a hazardous location)

What is a Fire Door Assembly?

• Any combination of a Fire door, a frame, hardware, and other accessories that together provide a specific degree of fire protection to the opening, while at the same time allows building occupants to pass through safely

• Each Manufacturer of the Fire Doors, Glazing and all of the other various Component Par ts must be Individually fire tested to achieve a fire rating in minutes.

• The Fire Rating of each opening is determined by the Sum Total of all the Component par ts of the Door Assembly, and based upon the Lowest Rated item in minutes. All items must be rated equally (All 90 min = 90 min Assembly) or

(20 min glass in 90 min Door = 20 min Assembly).

What is Visible Lite?

• The viewing area or exposed glass within the vision panel.

• Determines the Fire Rating as tested by the total square inches

(square meters) with a maximum width and height dimension.

• ie. 1296 square inches (0.836 m 2) max. width 36" (914mm), or max. height 54" (1372mm) – 45 minute rating.

• LoPro Formula:

- Cutout minus 1" (25mm)

= Glass Size

If the Anemostat literature says a specific visible lite size and minute rating (i.e. 1296 sq. in.,

0.836 m

at 90 minutes with FireLite), can I use that in any brand of wood or metal door?

No,

On visible lite sizes larger than 1296 sq. in. (0.836 m2) on 20/45 min. and 100 sq. in. (0.065 m2) on 60/90/180 min. Please consult with your Door / Frame Manufacturer’s procedures, for their maximum glass size tested.

• Size limitations (in Visible Lite Sizes) depend on the product and the application. They will also be dictated by the total assembly (ie door, vision frame, glass and glazing tape).

• Please consult www.anemostat.com for the most recent Size Limitations and Technical Data information.

Labeling

What do the Codes say about Labeling?

Does the fire rated glazing used in doors also have a permanent label and be safety rated?

YES,

according N.F.P.A –80, 2013, Section 4.4.1, “Only Labeled Fire Resistance - rated or Fire Protection - rated glazing material shall be used in Fire Door Assemblies when permitted by the door listing.” Section 4.4.2 says “Fire

Protection glazing and Fire Resistance glazing shall meet all applicable Impact Safety Standards.” Section 4.4.3 says

"Glazing materials in vision panels shall be installed in labeled glass light kits or in accordance with the fire door listing and shall be installed per the manufacturer's installation instructions."

Most building codes in Nor th America now require such a label, although enforcement of such requirements lags in some areas. Fire-rated glazing materials do not all per form in a similar manner.

Fire Protective vs. Fire Resistive

What is the difference between Fire-Protective and Fire-Resistive glazing systems?

Fire Protection Rated

• Glazing defends against the spread of flames and smoke.

• Designed to compar tmentalize smoke and flames and is subject to application, area and size limitations under the IBC.

• Typically is suitable where building codes allow “opening

protective” assemblies. Glazing is available with fire ratings ranging from 20 to 180 minutes, it is subject to area and size limitations under the applicable building code and/or authority having jurisdiction.

• This designation indicates the duration of the fire test exposure to which a fire door assembly or fire window assembly was exposed and for which it successfully met all acceptance criteria as determined in accordance with test standards such as

NFPA 252 / NFPA 257 / UL 9 / UL 10C.

Fire Resistance Rated

• Heat Barrier Rated Glass provides the same defense against flames and smoke as fire-protective glazing, and adds fur ther protection by blocking the transfer of radiant and conductive heat.

• Products are generally multi-laminates incorporating several layers

of glass with fire-resistive, intumescent interlayers or fire retardant-filled transparent units.

• Are considered a “wall,” and tested just like a brick, masonr y, or gypsum board assembly. Listings for these products classify them as “transparent walls” that are not restricted to 25 percent of a wall area when the framing system has a rating equal to the glazing.

• This class includes products also rated for Acoustical per formance, Blast and Bullet Resistance, and they are typically suitable where building codes require an assembly designated

“fire resistant” to enclose a space. Includes applications requiring a 60-minute or greater fire rating that must meet

temperature-rise criteria, such as stair wells, exit access corridors, or other fire barriers dividing interior construction. In these instances, the IBC requires the temperature rise on the non-fire side of the glass not to exceed 250 degrees Fahrenheit above the ambient temperature at the end of the fire test (generally 60 or 120 minutes). Such glass must also pass the hose stream test.

• Designed for materials or assemblies that have withstood a fire exposure as established in accordance with the test procedures such as NFPA 251 / ASTM E-119 / UL 263. This rating tests a product’s ability to block the transfer of conductive and radiant heat from a fire.

• Due to the need for special cutting and processing equipment, deliver y must be direct from the manufacturer. This extended lead-time is a consideration if glass requires immediate replacement. With a typical thickness of at least

3/4”, frames and glazing “stops” may require modification to ensure proper assembly.

To summarize, fire-protective glass is not designed to block or stop radiant heat; fire-resistive glazing does.

Fire-resistive glass is considered as a “wall,” tested just like a brick, masonr y, or gypsum board assembly. The ratings required by the U.S. building codes are determined based on applications for fire-protective and fire-resistive constructions. The application requirements are based on time-the time to allow for safe egress and to maintain the structural integrity of the building.

Safety Rated Glazing

What is all the talk I’m hearing about Fire AND Safety Rated Glazing?

What about Wire Glass? Isn’t Wire Glass Outlawed?

IBC CODE - SECTION 2406 SAFETY GLAZING

IBC 2000 and Prior Codes

Wire Glass - was 100% exempt from applicable Safety Standards in

Fire Doors.

For over 25 years CPSC granted Wire

Glass an exemption from complying with higher standards (Categor y I and II) of impact / safety in hazardous locations. Wire Glass was the primar y, low cost, and readily available product that would comply with fire rated door requirements. It will not however pass

Categor y I or II Safety testing, and was given an exemption from safety compliance for use in fire doors only.

IBC 2003

Wire Glass - a por tion of exemption was withdrawn for areas in schools, day care, etc. where children are present.

What does it mean?

Lawsuits involving injured children caused IBC to withdraw a percentage of the exemption. IBC 2003 says basically, if children are predominantly present,

(i.e. school, day care etc.) glazing in fire doors must be fire AND safety rated per section 2406. Exemption for Wire Glass in these areas only was withdrawn.

Now, other more expensive fire rated glazing products are availible that also comply with categor y I and/or II safety requirements.

IBC 2006 to Present

Wire Glass - 100% of exemption is withdrawn from code.

Plenty of Fire and Safety rated glazing products are now available. Wire Glass exemption is completely withdrawn.

Now, all glazing in fire doors must also be safety rated per section 2406 in hazardous locations, as originally intended per Categor y I and II.

Wire Glass (NON-Safety Rated) can only be used in

NON-Hazardous locations.

See pages 8 & 9.

What are the Differences Between Safety Glazing Standards?

CPSC 16 CFR 1201 and ANSI Z97.1-2004

In 1977, the U.S. Consumer Products Safety Commission (CPSC) adopted as a mandator y federal safety regulation

Safety Standard for Architectural Glazing Materials, codified at 16 CFR Part 1201.

ANSI Z97.1 is only a voluntar y safety per formance specification and test method. It does not attempt to declare when and where safety glazing materials must be used, leaving those determinations up to the building codes and to glass and fenestration specifiers.

ANSI Z97.1 uses two Separate Impact Per formance categories.

Impact Drop: 48-inch drop height test =

Class A

is comparable to the CPSC’s Categor y II

18-inch drop height test =

Class B

is comparable to the CPSC’s Categor y I

Size Criteria: “U” is for Unlimited size based on passing max test size

“L” is for Limited based on size area based on tested size

CPSC 16 CFR 1201

CATEGORY I:

Impact safety level designated by “code of federal regulations” par t 16. (16 CFR). “Categor y I” glazing materials are subjected to the impact of a 100 lb. bag swung from 18" drop height (approx. 150 ft/lb impact), with no single piece of glazing material greater than 9 square feet in sur face area. Cat I resembles an 85 lb. child running into the glazing material.

CATEGORY II:

Impact safety level designated by “code of federal regulations” par t 16. (16 CFR). “Categor y II” glazing materials are subjected to the impact of a 100 lb. bag swung from

48" drop height (approx. 400 ft/lb impact), with any piece of glazing material greater than 9 square feet in sur face area. Cat II resembles a full-grown adult running into the glazing material.

Bullet • Blast • Impact

Threat Exposure:

There are three threats regarding window glass and glazing systems. Forced Entry, Ballistic

and Explosive Blast Attacks.

Safety:

Provides for the reduction of the risk or occurrence of injur y, loss or death from accidental or natural

causes.

Security:

Provides for the reduction of the risk or occurrence of injur y, loss or death from the intentional actions of

man.

UL Protection Level Ratings

• Levels for Bullet-Resistant systems have been established by UL (Underwriters Laboratory), the primar y testing organization for materials used in these systems. While ratings extend to Level 8, the needs of most banks, credit unions, and convenience stores are well covered in Levels 1-3.

Ballistic Protection Level Ratings

• Total system of frame, door and glazing material must absorb the energy from the projectile.

• Framing system must also stop the potential threat and retain the glazing system during attack. Bullet resistant glazing in a non-cer tified frame will not ensure the desired level of protection.

• Ballistic glazing cer tified to meet a ballistic standard, must be retained in a cer tified framing system

What about Forced Entry?

• Is the attempted penetration of a door, window and walls using a wide variety of tools.

• Tools may include, but are not limited to sledge hammers, pr y bars, wood splitting mauls, fire axes, battering rams, gasoline, acetone, propane torches and CO2 fire extinguishers.

• Standards include ASTM F1233 for glazing material, ASTM F588 for windows, and ASTM F476 for doors. These standards have multiple levels of ratings based on the severity of the threat.

Glazing is not required by code to:

1. Resist any cer tain level of burglar y attempts - Forced Entry Resistance

2. Defeat projectile penetration - Ballistic Resistance

3. To defeat and maintain integrity from explosive ef fects - Blast Resistance

- These utilize independent testing laboratories test methods and standards that subject glazing to these specialized classifications of attack.

Explosive Blast Attacks

• Based on the deliberate or intentional acts of man. Can also be based on industrial or chemical blasts occuring in refineries, manufacturing, or R & D facilities.

• Four generalized damaging ef fects are generated from explosive blasts:

1. Primar y cause, or the shock or initial blast wave from the explosion.

2. Damage from the impact of fragments from the encasement material.

3. Hot gasses and flame igniting fires, burn victims and its subsequent damage.

4. Ground vibrations or “seismic loading” causing ef fects similar to that produced by an ear thquake.

Explosive Blast Testing Requirements

• Centered around the air-blast standard. Test protocol and procedures are defined by ASTM F1642-96.

The standard ef fects the whole sur face area of the test specimen, and can be reproduced without substantial variances. Standard is for testing glazing systems including those fabricated with glass, plastic, glass - clad composites, laminated glass, glass/plastic glazing materials and film-backed glass.

• Test is usually conducted in a shock tube, but can also be in an open-air arena capable of accommodating the detonation types of explosives, charge weights, peak positive, incident or reflected pressures, and encasement materials, stand-of f distances and positive phase durations. Open-air arena atmospheric conditions cannot be as easily regulated as in the chamber. Another advantage of the shock tube test is replicating secondar y rebounding pressures and durations, more commonly associated with high-rise urban environments.

STC - Sound Ratings

What is an STC rating?

(Sound Transmission Class)

• STC is a numbered rating system derived from measured values of sound transmission loss in accordance with ASTM E90-09,

Standard test method for laborator y measurement of airborne

sound transmission loss of building par titions ASTM E2235-04,

Standard test method for determination of decay rates for use in

sound insulation test method. ASTM E413-04, Classification for

rating sound insulation. STC ratings provide an industr y accepted method for comparing the sound reduction ef fectiveness for various sound doors and windows.

Define Sound Transmission Class (STC) and Transmission Loss (TL)

• Door’s ability to reduce noise is called its transmission loss (TL) ef fectiveness. TL is a value given in decibels, which is determined by measuring sound pressure levels at a cer tain frequency in the source and receiving rooms.

Adjusted dif ference between the two levels is the TL of the door.

• TL ratings for a door are taken across a range of frequencies, which makes it dif ficult to compare the ef fectiveness of dif ferent doors. STC ratings solve the problem by giving a number value to the acoustical per formance for a door. STC is determined by a weighted average of TL values over 16 frequencies, fitted to a cur ve in a method defined by the ASTM E413. The higher the STC value, the better the rating and sound protection.

Medical X-Ray View Window Design Requirements:

NCRP #49 requires under Radiographic Installations 5.3.2.

“Provision shall be made for the operator to obser ve and communicate with the patient from a shielded position at the control panel. When an obser vation window is provided it shall have a lead equivalence at least equal to that required of the par tition (or the door) in which it is located.”

• AIA and FGI (Facility Guidelines Institute) Guidelines for Design and Construction of Health Care Facilities requires under Shielded Control Alcoves 5.5.4.4. “Each X-Ray room shall include a shielded control alcove. This area shall be provided with a view window designed to provide full view of the examination table and the patient at all times, including full view of the patient when the table is in the tilt position or the chest x-ray is in use. The window(s) should be at least 18” x 18” (457 x 457mm) and centered 60” (1.5m) above the finished floor.”

*Please Note the above uses of the word “shall” is a requirement, and use of the word “should” is a recommendation

X-Ray Glass for Radiation Shielding:

Is specifically formulated to ef ficiently attenuate and protectively shield against

X-Ray Gamma Radiation by using a combination of a heavy density and a high content blend of heavy oxides and minerals for maximum radiation resistant shielding per formance while utilizing optimum glass thickness mass, while providing excellent optical clarity and a non-browning optimal level of light transmission. Is code compliant, radiation life and safety protection for the medical technician and allows an excellent clear view of the patient during critical medical diagnostic imaging procedures.

Lead Shielding Equivalences:

X-Ray Glass is readily available in 4# and 8#. Higher ratings available on request.

X-Ray Safety Glass is Permanently Labeled:

Provides required impact resistance for use In doors or walls or for additional seismic safety. Provides a clear view, while shielding X-Ray/Gamma radiation, and 95% of UV protection.

X-Ray Safety Glass is NOT fire-rated, tempered, impact proof, shatter proof or scratch resistant. Fire-rated designs are usually available upon request.

Visible Light Transmission:

Glass transparency results may var y depending upon X-Ray glass thickness, glass composition, light frequency, spectrum, and or sources such as natural sunlight, UV, incandescent, florescent, halogen, sodium, mercur y, metal halide or LED and light transmission measurement methods and controls.

Lead Equivalence:

Lead has the proper ty of blocking/ absorbing x-ray radiation due to its high density. Various thicknesses of pure lead provide dif ferent levels of protection or attenuation (reducing the Intensity of radiation passing through) as material under specified conditions. The protection provided by this type of sheeting is compared with that of pure lead and referred to as “Lead Equivalence”. Lead equivalence as specified for materials used in diagnostic X-Ray rooms is measured at 150 kV (X-Ray beam dosimetr y defined as “distribution of radiation emitted from a source of ionizing radiation”) unless indicated other wise.

All calculations for shielding requirements should be determined by a qualified health radiation physicist currently recognized by the state in which the project occurs

Hurricane Rated Glazing

The Test Methods and Specifications

There are two basic test methodologies utilized in hurricane testing; HVWZ TAS 201 and TAS 203 (Florida Building

Code) and ASTM E1886. These documents describe the technique used to propel the timber through the air and impact the fenestration system, and also provide the specifics for subjecting the glazing to the required repetitive cyclical loads. The ASTM test method has a corresponding specification, ASTM E 1996, that indicates what missile size shall be used depending upon application and wind speed (see figures 3 and 4), location of impact, pass/fail criteria and substitution limitations. For example, below 30 feet from grade is typically the zone for impact by a lumber

(large missile), whereas above 30 feet from grade is the zone for impact by 2 gram steel ball bearings (small missile).

Missile impact standards and testing

The ICC Standard for Residential Construction in High Wind Regions specifies that doors, skylights, and windows in the windborne debris region shall be either impact resistant or protected with an impact resistant covering. The

American Society of Civil Engineers’ newly developed wind speed maps define the wind-borne debris region as the regions within one mile of the coastal mean high water line and where ultimate wind speeds of 130mph or greater.

Per the Florida Building Commission 2010 Code, ASTM E1996 wind zones are to be specified as follows:

ADA Standards / Glazing - Wood Doors

Americans with Disability Act - 2010 ADA Standards for Accessible Design

The 2010 ADA Standards, as adopted by the Depar tment of Justice (DOJ) in September 2010, became mandator y on March 15, 2012. DOJ is allowing immediate use of these standards as an alternative to its original 1991 standards but requires that the selected standard be applied consistently to a project. DOJ’s ADA standards apply to facilities covered by the ADA, including places of public accommodation, commercial facilities, and state and local government facilities. They do not apply to transpor tation facilities, including bus stops and rail stations, which are subject to similar standards issued by the Depar tment of Transpor tation.

What does ADA say about Vision Frame placement?

404.2.11

Vision Lights. Door, gates, and side lights adjacent to doors or gates, containing one or more glazing panels that permit viewing through the panels shall have the bottom of at least one glazed panel located 43 inches

(1090 mm) maximum above the finish floor.

What about Glazing in Wood Doors?

Does it have to be factory installed?...Read and Decide

NFPA-80-2013, 4.4.3.1 reads: For new wood doors, glazing materials in vision panels shall be installed in labeled glass light kits or in accordance with the fire door listing and shall be installed in accordance with inspection ser vice procedure and under label ser vice.

What this means is that all glass in new wood doors must be installed either by the door manufacturer, or in a licensed door shop, following the procedures and instructions of both the door manufacturer and light kit manufacturer.

It also ensures that all components of the glazed assembly in the new wood door have been properly installed per the manufacturer’s follow-up ser vice procedure.

World Wide Fire Test Standards

FIRE TEST STANDARDS – Worldwide

US/CANADIAN STANDARDS – WITH hose stream test (UL & WHI)

Steel and Wood Doors (UL-10C, UBC 7-2 and UBC 7-4)

• 20 & 45 minutes at 1296 Sq. in. (0.836 sqm) Visible Lite, unless other wise tested.

60, 90, & 180 minutes at 100 sq. in. (0.065 sqm) Visible Lite, unless other wise tested.

• Is based on a fire, then hose stream test for both wood (timber) and steel door assemblies.

• US does not require hose stream test for 20 minute tests.

• Follow up inspection by UL or Warnock Hersey is required and each product is required to have a

certification label on each individual item in the assembly. Compliance with the implementation of the label is enforced by UL /WHI follow up inspection in the respective factor y.

• Ratings are based upon a maximum square inch area (or square meters) with a maximum width and maximum height dimension, equaling the maximum area tested, measured in Visible Lite.

• Vision panel and the steel or wood (timber) door must also have UL approval to install this over sized vision panel and glazing assembly into their door, and it should be par t of their approved test procedures or as we state in the

Anemostat literature “Must be used in an appropriately tested door assembly.”

• Once products are been tested and approved by UL or WHI, the cer tification verification is the UL / WHI logo imprinted on the specific product.

• Test Repor ts are rarely if ever furnished due to the proprietar y information included. The individually labelled product makes up for the need for a test repor t. Likewise, product cer tificates can be provided to replicate website information on UL letterhead when required.

BRITISH STANDARD (BSI or BS EN) WITHOUT hose stream test

Timber Doors – 30 & 60 minutes (E & EW)

Steel Doors – 30 & 120 minutes (E & EW)

BS EN #: as European standards are agreed they are adopted as British Standards and so get a BS EN number.

E- Integrity - The ability of the system to keep back flames, smoke and fumes. No flaming on the non-fire side is permitted within the approved time classification

EW – Partial Radiation - EN 357 classification for par tial insulation or reduced heat radiation for fire resistant glass. The length of time that a construction can give fire resistance in relation to the passage of flames and smoke as defined in BS 476: Par t 20. In addition to the integrity, the ability of fire-resistant systems limit the radiant heat on the non-fire side to15 kW/m² at a distance of 1 m to the sur face, in order to prevent for example the ignition of goods on the protected side.

• Like the US standard, the British Standard incorporates width and height test limitations based on square meter area. Basic dif ference is that the maximum width and height dimensions are based upon the door aper ture (cut out) as opposed to the US standard which is measured in visible glass, and no hose stream test.

• Unlike the US standard, labels are not required, nor is there an in factor y follow-up inspection done on products tested to the British Standard. Products are tested, then “assessed” by the Test Lab for continued compliance ever y five years. Test Repor ts are issued to prove compliance with tested standards

EUROPEAN STANDARD (EN) - WITHOUT hose stream test

EN 1634: Fire resistance tests for door shutter assemblies

Par t 1: Fire doors and shutters.

Based on a Fire using a Temperature Rise measurement,

EI-30, EI-60, and EI-90 (minutes) regarding Integrity and Insulation for fire resistant glass.

All Doors – EI-30 – 30 minutes

EI-60 – 60 minutes

• EI - Insulation - EN 357 classification for Insulation, fire resistant glass. In addition to the integrity, the ability of glazed screens or doors to limit the average temperature rise on the non-fire side to 140°C and the maximum temperature rise to 180°C above ambient temperature.

Hose Stream Test

Testing Fire-Rated glazing for Door and

Window Assemblies

• Rated from 20 minutes to 3 hours. Rating reflects the amount of time the Assembly is to remain in place to stop the spread of fire and smoke.

• Building codes dictate where rated products will be allowed in a building. Codes are designed to take into account how long it will take people to exit a building in the event of a fire.

• Fire Ratings are based on testing done by independent testing facilities, such as

Under writers Laboratories, using Positive Pressure test standards such as UL 10C, UBC 7-2 and

UBC 7-4 simulating real fire conditions. Testing Is based on complete door, frame and glazing system In a wall assembly. This assembly is then subjected to test standards that include two

Fire hose impacting fire rated glass immediately after fire test.

required elements: a “Fire” then a “Hose Stream Test.” Within two minutes of completion of the fire por tion of the test, the side of the assembly exposed to the furnace or “Hot Side” of the glass and framing is subjected to the Hose Stream

Test and is sprayed with water from a fire hose at pressures and durations specified in NFPA 257, Table 6.2.3.

Why is the “fire hose stream” (thermal shock) test so important?

• In real world fires, the glass and framing systems that have been exposed to the heat of flames will most likely be subjected to water from a fire hose, sprinklers or fire extinguishers.

• When one area of the glass/ framing system is hot while another area is cool, stress on the glass, or thermal shock occurs. Since the glass is expanding and contracting at the same time, the glass can shatter and vacate the frame, allowing for fire or smoke to spread. The Hose Stream Test Is to verify the integrity of the complete glass, frame and door system.

NFPA 257 states, “The Hose Stream Test provides a method for evaluating the integrity of constructions and assemblies and for eliminating inadequate materials or constructions. The cooling, impact, and erosion effects of the

Hose Stream provide tests of the integrity of the specimen being evaluated.” In the United States, the Hose Stream Test is required for all fire ratings of 45 minutes or greater. Canada requires the test for all fire ratings. The Hose Stream Test is an integral par t of many Fire Testing standards such as ASTM E 119.

• Building and Fire Codes are ver y clear on why the Hose Stream Test is critical, and recent proposals to eliminate the test have been soundly defeated. The International Code Council (ICC) has re-affirmed the impor tance of the Hose

Stream Test for life and proper ty safety, on many occasions. Responding to proposals by a product manufacturer to lessen or eliminate the test requirements, in 2006 the ICC’s Fire Safety Code Development Committee stated that these actions “…would reduce the level of life safety which the code has generally required and provided.” The Committee went on to note that the issue has been debated a number of times and that “it has always been defeated.” (2006 ICC

Public Hearing Results, FS121-06/07 and FS107-06/07). In a more recent round of code reviews, in Februar y 2008, the

ICC rejected additional proposals to change the Hose Stream Test requirements.

Is fire-rated glass really necessary if I use sprinklers?

IBC 2012 clarifies that fire ratings must be based solely on a material’s own per formance. In section 703.4, “...the fireresistance rating of a building element, component or assembly shall be established without the use of automatic sprinklers or any other fire suppression system...”

• While sprinklers help to save lives, they are no substitute for the use of passive fire-rated glazing materials. If sprinklers do not activate due to faulty manufacturing, loss of water pressure, or any other reasons, fire-rated glass will still per form its critical function.

What about a fire rated product with several limitations on its use?

• Architects and designers should always be war y of product “listings” that carr y what appear to be unusual limitations.

Although NFPA standards are ver y clear that both the fire test and hose stream test are required, one fire-rated glazing material on the market indicates a fire rating of “60 minutes”, but then goes on to say, “This product does not meet the hose stream requirements of the test standards”. And, “This product protects from fire from one direction only. The identified face MUST be installed facing the direction of expected fire attack.” Such limitations should raise red flags, and prove how impor tant it is to thoroughly check out products thoroghly to insure how a laborator y “listed” product may not be exactly what you thought it might be. This manufacturer also asks Architects and Specifiers to seek local exemptions to well established national testing requirements and building codes, in order to install this product in buildings.
