Is spray foam insulation worth it in Texas?

Absolutely. Austin's extreme summer heat makes spray foam insulation one of the highest-ROI home upgrades available. It creates an airtight seal that traditional fiberglass batts cannot match, reducing HVAC load by up to 40%. Most Austin homeowners see payback within 3–5 years through lower energy bills.

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

Open-cell spray foam is softer, more affordable, and excellent for interior walls and attics where moisture is not a primary concern. Closed-cell spray foam is denser, acts as a vapor barrier, and delivers a higher R-value per inch — making it ideal for crawl spaces, exterior walls, and areas with potential moisture exposure.

How long does spray foam insulation last?

Spray foam insulation is one of the most durable insulation options available, typically lasting the lifetime of the building — 80 years or more. Unlike fiberglass batts that sag and settle over time, spray foam maintains its shape, seal, and R-value indefinitely when properly installed.

How long does spray foam insulation installation take?

Most residential spray foam jobs in Austin take one to two days. A standard attic can typically be finished in a single day. After spraying, the foam cures within hours and you can re-enter treated areas the same day in most cases.
