ATTIC SEALING

Applying fast curing spray polyurethane on attic floors prior to installing blown-in or batt insulation provides protection against air leaks.  Unlike fiber insulation alone, Spray Polyurethane Foam greatly reduces air transmission between the conditioned livings space and the attic, which can account for a large portion of energy loss.

DUCT SEALING

Sealing joints and penetrations around rigid metal HVAC ducts with two components polyurethane in un-conditioned attics and crawl spaces will reduce energy loss, provide greater comfort, and increase the efficiency of the HVAC system.  Sealing around exhaust fan ducts can help prevent condensation and dripping back through the fan assembly.

Loose-Fill and Blown-In Insulation

Loose-fill insulation consists of small particles of fiber, foam, or other materials. These small particles form an insulation material that can conform to any space without disturbing structures or finishes. This ability to conform makes loose-fill insulation well suited for retrofits and locations where it would be difficult to install other types of insulation.

The most common types of materials used for loose-fill insulation include cellulose, fiberglass, and mineral (rock or slag) wool. All of these materials are produced using recycled waste materials. Cellulose is primarily made from recycled newsprint. Most fiberglass products contain 40% to 60% recycled glass. Mineral wool is usually produced from 75% post-industrial recycled content.
