Benefits of Clean Insulation

Temperature Regulation

Insulation works to prevent the transfer of heat through the walls, ceiling, and floor of your home. When some rooms are better insulated than others, the air temperature from room to room can change dramatically. Cold floors, cold walls, or excessive heat in upstairs and attic areas are signs that your home is not well insulated.

Unwanted air transfer causes your heating and cooling systems to work overtime to compensate for the energy loss. The installation of new insulation, however, in key areas of your home, helps regulate the house temperatures and reduce your energy costs.

Keep Moisture Out

  • Holes or cracks in an attic or crawl space allow moisture and water to enter into the structure of your home. Mold and mildew thrive in the dim, warm conditions of the attic, crawl space, and wall cavities. The presence of mold and mildew drastically decrease the air quality of your home and causes decay to a home’s structure.
  • Prescriptive air sealing, duct sealing, and the correct choice of insulation can lock out moisture and keep your attic and crawl space dry and toxin free.

Save Money

Poor insulation in your attic and crawl space could be costing you money! Homes that lack proper insulation are less energy efficient, thereby causing you to spend more on your energy bills and reducing the life of your HVAC unit because it cycles more frequently. Depending on the condition of your current insulation, homeowners who invest in new insulation on average see an energy savings of 30%-80%.

Types of Crawl Space and Attic Insulation We Install

Spray Foam Insulation

Spray foam insulation is a polyurethane foam generated through a chemical reaction between isocyanates (A-side) and polyol resins (B-side). When sprayed out of the tip of the spray foam gun, the substance gradually expands, filling in the cracks and crannies of your crawl space or attic before curing. Spray foam insulation is the most effective material for sealing your crawl space or attic available.

Fiberglass insulation is usually installed as batts of insulation that are rolled or laid out onto a surface, such as flooring, ceilings, or in wall cavities. However, blown fiberglass is becoming more and more popular, comprising one of the main insulation jobs we’re asked to do. This type of insulation is made of a mixture of natural sand and recycled glass.

Cellulose insulation is made from recycled paper products, primarily newsprint. Its recycled material content is very high, generally between 82-85%. The manufacturing process reduces the paper products to very small pieces, which are then fiberized and mixed with a flame and insect retardant, usually mineral borate or ammonium sulfate. Cellulose insulation is primarily found in pellet form as a blown-in insulation, but can be manufactured in batts as well.



Cotton has become a favorite of the environmentally friendly community. Recycled blue jeans have been used in its production, as well as other natural cotton fibers gleaned from industrial scrap. Most cotton insulations consist of 85% recycled cotton and about 15% plastic fibers, which are generally treated with boric acid as a flame retardant. Cotton insulation is non- toxic, and can be installed without respiratory or skin exposure protection. Unlike fiberglass insulation, no reports have been made of itchiness or burning of the skin when in contact with cotton insulation.
