Insulation, especially attic insulation, in conjunction with air sealing and a radiant barrier work together to keep your Austin, Georgetown or Pflugerville, Texas area home more comfortable and energy efficient year-round.

The Importance of Air Sealing, Attic Insulation and a Radiant Barrier

Your home’s building envelope consists of the pressure boundary and thermal boundary. The pressure boundary needs to be air sealed to keep air from moving in and out, since air can carry unwanted heat (or cold air), moisture and pollution with it. The thermal boundary consists of insulation and works to keep unwanted heat (or cold air) from entering and exiting.

A key area of your home that, if not properly insulated and air sealed, can cause extensive energy loss, is the attic. Insulating your attic with spray foam insulation and fiberglass, air sealing and installing a radiant barrier on your roof will improve energy efficiency and result in significant savings. Your home’s conditioned air will stop escaping, keeping you more comfortable.

In the Austin, Texas area, homes lacking adequate insulation, particularly in the attic, waste excessive amounts of energy and are far less comfortable to live in. Upgrading your home’s insulation is an excellent way to reduce your cooling and heating bills. It will also make your home more comfortable, keeping it cooler during the heat and warmer during brisk winter nights.

Spray Foam

Spray polyurethane foam (or “SPF”) insulation has the ability to conform to any space, forming an excellent air barrier, in addition to a thermal one. At Hill Country Insulation, we usually use spray foam insulation as the first step in air sealing and insulating a home, particularly in the attic, before installing an additional layer of fiberglass insulation.

Radiant Barriers

Homes in the Austin area need a radiant barrier in the attic to help reduce heat gain during the sweltering Texas heat and to help decrease exorbitant home cooling costs. Radiant barriers are made of a highly reflective material that reflects heat instead of absorbing it. In order to keep your home cool, a radiant barrier in your attic needs to be combined with adequate insulation and air sealing.

Air Sealing

Air leakage in Texas Hill Country homes is an all-too-prevalent issue. Gaps and cracks in a home’s building envelope let air flow readily in and out. As air moves it takes heat, moisture and pollution along with it. By air sealing your home, you will experience more consistent indoor temperatures, improved indoor air quality and a reduced chance of moisture issues.

Stop letting your home's energy disappear.

Get comfortable and start saving.
