A: Spray foam insulation (SPF) is a two‑component foam that expands on application, creating an airtight seal in walls, attics, crawl spaces, and metal buildings. It offers superior R‑value per inch (R‑3.4 to R‑6.7/in for closed‑cell) vs traditional fiberglass or cellulose .
Q2. Closed‑cell vs open‑cell spray foam—what’s better?
A:
-
Closed‑cell: Dense, acts as a moisture barrier, ideal for exterior walls and roofs, adds structural strength.
-
Open‑cell: Softer, great for interior soundproofing, less expensive. Both expand to fill gaps, but closed‑cell offers higher R‑value and moisture protection Thumbtack+8Wikipedia+8Koala Insulation+8.
Q3. How much energy can I save with spray foam insulation in Dallas?
A: Homes using spray foam often see a 20–50% reduction in heating and cooling costs due to minimized air leaks and superior thermal resistance—the DOE estimates up to 40% energy loss prevention .
Q4. Is spray foam safe for indoor air quality?
A: Once cured, spray foam becomes inert. Freshly applied foam emits VOCs, so proper ventilation and professional installation with protective equipment are essential. After curing, indoor air quality remains unaffected .
Q5. Why choose spray foam over fiberglass insulation?
A: Spray foam seals air gaps and provides continuous insulation—unlike fiberglass batts, which can leave air leaks and degrade over time. May also be eligible for federal tax credits for energy efficiency .
