Low-E Insulation For Homes and Businesses

thermo-seal offers low-e insulation for homes and businessesESP Low-E® Housewrap does more than simply reduce drafts. This closed cell polyethylene foam is heat bonded to a pure aluminum facing and then perforated. The result is a housewrap that not only meets ICC requirements for water resistant barriers but also adds insulation to the exterior of the home blocking up to 97% of radiant heat.

This is important because this will help save money on utility bills over time as it keeps conditioned air within the building instead of letting it escape to the outdoors.
