Open Cell Spray Foam Insulation in Lubbock, TX

Open-cell spray polyurethane foam is the most cost-effective insulation upgrade for attics and interior walls in Lubbock homes. It expands to fill every cavity, seals air leaks, and dampens sound — all in one application.

How Open-Cell Foam Works in Lubbock

Open-cell spray foam is a low-density polyurethane that expands roughly 100x its liquid volume. Unlike closed-cell foam, it has tiny air pockets in its structure, which makes it lighter, less expensive, and slightly less effective per inch — but still 2-3x better than fiberglass batts.

For Lubbock homes, open-cell foam is the right choice for:

• Attics — fills every joist bay, eliminates drafts, prevents ice damming in winter
• Interior walls — adds soundproofing between rooms, especially media rooms and bedrooms
• Cathedral ceilings — replaces inadequate batts in older homes
• Vented crawlspaces — when budget doesn't allow closed-cell encapsulation
