Ultra CBF Under Slab Insulation - 4' X 75' (300 sq ft)

EcoFoil Under Slab Insulation (1/4" to 5/16") thick, is manufactured with a single layer metalized reflective sheet laminated between two layers of strong polyethylene bubbles. EcoFoil Under Slab Insulation has a compression strength of 140 PSI. Our insulation is thin and lightweight, making it easy to conform to your grade and reduces any worry of leaving pockets or voids like traditional insulation.
