ICC products have been tested by a variety of laboratories including Underwriter¹s, Factory Mutual, Ohio State University and Southwest Research Institute. These tests subjected our insulation to direct fire exposure measuring both flame spread and fire endurance of the product when exposed directly to the fire.

These results include the following:

1. Class A Flame Spread 5 Smoke Developed 5
2. Protection over combustible wood building materials
3. Protection over combustible plastic building materials such as polyurethane and Styrofoam
4. Protection over structural steel to supplement automatic sprinkler protection in preventing structural failure temperature of the steel in high fire hazard occupancies
5. Protective coating to the underside of Class II insulated steel roof deck construction to sufficiently lower the rate of fuel contribution from Class II deck components to qualify the construction as Class I allowing automatic sprinkler protection to be omitted when permissible under Factory Mutual Standards.

In all of the above instances, K-13 was tested exposed directly to the fire under laboratory established conditions. It is clear that these products possess fire resistive qualities in and of themselves.

In both load bearing and non-load bearing interior and exterior walls, the wall structure itself (framing and panels) must provide the fire resistance necessary to withstand the ASTM E-119 procedure for the required duration (1, 2, or more hours). When placed within tested wall cavities, ICC products will not reduce the fire resistance of the wall assembly.

Moisture

With reasonable ventilation drying will occur quickly and constantly. Moisture absorption testing indicates cellulose resists absorption and passes ASTM requirements of less than 15% gained under extreme conditions. Thermal performance is affected only slightly; a 10% moisture gain reduces thermal performance by only 15% and is restored immediately as the insulation dries out.
