Frost Mat/Curing Mat
Frost mats have extremely low thermal conductivity (0.035W/km), so are highly suitable to provide thermal insulation. Used horizontally, their thermal insulation or U value is 2.3. Thermal insulation is retained even in wet conditions. Due to the closed cell structure of the polyethylene, water absorption is very low and frost mats are highly resistant to abrasion and tearing.

Crack Inducer Bottom
