HMI’s Thermolok cellulose insulation is superior insulation for sound control, fire protection, mold, and mildew prevention, as well as energy efficiency. All of our insulation products are made from recycled materials and are produced from over 50% renewable energy making HMI products the greenest in the market. Cellulose insulation is a blow-in insulation that creates a tight seal in walls and attics limiting air movement. In turn, this creates a higher thermal resistance to temperature change inside structures saving the owner money on energy bills.

Cellulose insulation is considered a premium insulation without the added costs. It does not itch like fiberglass or off-gas like foam. Cellulose insulation can be applied in attics, in between walls, on metal and concrete surfaces. Projects include residential housing, hotels, offices, apartment complexes, livestock farms, industrial buildings, and parking garages.
