Frequently Asked Questions About Insulation

What is the difference between open-cell and closed-cell spray foam?

Open-cell foam is lighter, expands more to fill cavities, and is generally used for interior walls and attics to dampen sound and stop air. Closed-cell foam is denser, acts as a vapor barrier, adds structural strength, and has a higher R-value per inch, making it better for exterior applications or areas with moisture risks.

How does insulation improve indoor air quality?

By creating an air-tight seal, modern insulation prevents outdoor allergens, dust, and pollutants from entering your living space through gaps in the building envelope. It also helps control humidity levels, which significantly reduces the likelihood of mold and mildew growth inside walls and attics.

Can insulation be installed in an existing home without tearing down walls?

Yes, for existing walls, we often use the "drill and fill" method or retrofitting techniques. However, installation in attics and crawl spaces is straightforward. If you want spray foam in walls, it is easiest during a renovation, but blown-in options or injection foam can often be applied with minimal intrusion.

How long does spray foam insulation last?

When properly applied, spray foam insulation does not settle, shrink, or degrade like traditional fiberglass or cellulose. It is designed to last for the life of the building, providing permanent thermal resistance without the need for replenishment or top-ups over time.

Will upgrading my insulation really lower my utility bills?

Absolutely. Heating and cooling account for the largest portion of average energy usage. By sealing air leaks and increasing thermal resistance, your HVAC system runs less frequently and more efficiently. Many homeowners in Texas see significant reductions in their monthly energy costs after a professional insulation upgrade.
