Attic Insulation

Blown-In Insulation

Is your St. Louis or St. Charles area house a little too hot in summer and a bit chilly in the winter? You may need more insulation. A perfect supplement to what you have already is blown-in insulation, such as cellulose, fiberglass, or spray foam insulation from Gateway Environmental Roofing Solutions.

These types of insulation are used in the attic, walls, and floors to lengthen the service life of your roofing system, increase your home or facility’s energy efficiency, and provide better ventilation. And, because insulation keeps extreme temperatures out, you save on your utility bills. You can, in fact, save up to 40% on heating and cooling bills with the right insulation system, more than justifying blown-in insulation costs.

Spray Foam Insulation

Spray polystyrene foam (SPF) insulation is possibly the most effective type of insulation for your home. Because spray foam insulation expands and hardens during installation, it entirely fills each cavity, effectively creating an airtight barrier for your home or commercial facility. Spray foam insulation is mixed on-site and must be installed with care. Our licensed technicians have years of experience so you can rest assured you’ll get the best installation possible.

Types of Spray Foam

There are two types of spray foam insulation: half-pound foam and two-pound foam.

  • As the names imply, half-pound foam or “open cell foam” is a lighter, greener option that doesn’t contain HFCs as a blowing agent. It acts as an air and sound barrier and has an R-value (thermal or heat resistance rating) of 3.5 per inch.
  • Two-pound foam or “closed-cell foam” has better insulating properties with a higher R-value (thermal resistance rating) of 6 per inch and is better suited for direct application to your roof’s sheathing. It also acts as a water barrier and can add structural strength.

Spray foam insulation starts as a liquid and is mixed during the spraying application. It must be applied with great care – improper or rushed installations can not only ruin your home, it can lessen the effectiveness of your overall insulation system. Preparation and technique are keys to an effective spray foam installation. Gateway is your St. Louis area expert who can help you make the best spray foam insulation decision for your needs.

Other Types of Blown-In Insulation

Fiberglass and cellulose are also common types of blown in insulation and can be less expensive than spray foam insulation. Cellulose is a popular option, as it is often thought of as more environmentally friendly because it comes from recycled newsprint and cardboard which have been sprayed with a fire retardant.

Fiberglass is effective at preventing moisture buildup in your insulation system, but installation can sometimes disperse loose fiberglass particles throughout your home. An experienced insulation installer from Gateway Environmental Roofing Solutions will know how to combat settling and other drawbacks of blown in insulation through proper installation technique.
