Benefits of Polyurethane Insulation

Polyurethane insulation Keeps building cool, insulating the roof will make building interiors cooler and therefore more comfortable. This will lessen the need for cooling and lower energy used for air-conditioning. This will help reduce climate change in the long run. Polyurethane vs other insulation (R value per inch) Polyethylene foam: 3 Rock wool roll: 3 - 3.85 Polyurethane foam (sprayed): 5.5 - 6.5 Advantages of using PU 1 inch of PU = 2 inches of other materials. Insulation will be thinner and therefore lightweight. This means that for roof applications, structural load will be less. There are different applications like...
