1. WHAT IS THE SIGNIFICANCE OF A 25/50 FIRE RATING
Most building codes require faced metal building insulation to have a Flame Spread Rating of 25 or less and a Smoke Developed Rating of 50 or less when tested in accordance with ASTM E84 or UL 723. Note: ASTM E84 and UL-723 are used interchangeably. UL-723 is Underwriters Laboratories designation for the E84 test procedure. Code officials typically accept data by either procedure
2. HOW DOES UV AFFECT FACINGS
"Ultraviolet light (UV) will degrade unprotected plastic.LAMTEC's facings are manufactured with plastic films containing UV inhibitors and are designed for interior applications. Facings containing plastic films are not recommended for building structures (such as pavilions) with open walls.Sources of UV are sunlight and lighting fixtures.It is desirable to specify low UV output lighting.UV can be reflected off of surfaces such as floors.Foil facings are not affected by UV and should be considered for application with high UV exposure."
3. DOES TAGOFOIL OFFER A WARRANTY
Tagofoil warrants that the facing material is free of manufacturing defects for a period of 10 years from date of shipment from the factory, subject to those Terms, Conditions, Limitations listed below.
4. WHAT HAPPENS WHEN A FACING BECOMES WET AFTER INSTALLATION?
Typically, insulation facing will not be affected by limited exposure to water if allowed to fully dry. Prolonged exposure to water can potentially result in a loss of certain physical properties.
5. WHAT IS THE MAXIMUM INDOOR HUMIDITY THAT AVOIDS MOISTURE PROBLEMS?
"The maximum recommended continuous indoor relative humidity (RH) varies from 30% to 45%, depending on geographic location.General guidelines by region of the country can be found..An engineer should be consulted to determine the correct HVAC design for a specific facility."
