Insul-Tarp® is a patented revolutionary product like no other on the market today. Its lightweight, Space Age design integrates closed cell foam and an aluminum reflective material with a protective poly coating all within three thin layers. The durable poly coating protects the insulating material from potentially damaging surfaces and is impermeable to moisture, helping it to maintain a high R-value in a minimal amount of space. The physical characteristics and overall design of Insul-Tarp® make it the most effective product for insulating under concrete slabs in Residential, Commercial and Agricultural radiant heating systems.
Insul-Tarp® insulation was designed specifically for under-slab applications. Insul-Tarp® provides excellent thermal performance and a vapor barrier all in one easy to use product. In most applications the ground temperature that the insulation is directly exposed to is a consistent 50-55 degrees. Foam board insulation will eventually stabilize at that temperature level. Therefore, the foam insulation provides a consistent drain on the radiant system and the slab. Because of the innovative combination of layers of insulation and aluminum, Insul-Tarp® allows the slab to reach a desired temperature quicker; therefore the heating system performs more efficiently. Insul-Tarp® stands alone.
