Insulation & Foam

Walder Foundation Products supplies contractors with a full range of insulation and foam products for crawl space, basement, and foundation projects. Our inventory includes batt insulation, blown-in insulation, foam board, and spray foam sealants from trusted manufacturers like Johns Manville, DAP, and Terma-Foam®.

Batt Insulation
We stock fiberglass batt insulation in R-19 and other common R-values, available in kraft-faced and poly-encapsulated options. Poly-encapsulated batts reduce itch and dust during installation, making them a common choice for crews working in tight crawl space conditions.

Blown-In Insulation
For attic and cavity applications where batt insulation isn't practical, we carry blown-in cellulose insulation, including borate-treated options that offer added pest resistance.

Foam Board Insulation
Terma-Foam® rigid foam board provides continuous insulation and a thermal break for crawl space and foundation wall applications. Termite-treated foam board is available for jobs where pest protection is part of the specification.

Spray Foam Sealants
DAP Touch 'n Seal spray foam sealants seal gaps around pipes, wiring, and other penetrations. Fire-rated formulas meet Type V residential fireblock requirements, and pest-control formulas help block entry points for mice, insects, and other pests.

Fastening Guns & Insulation Accessories
Round out your insulation job with fastening guns for foam board and vapor barrier, plus insulation hangers designed to support batt insulation beneath floor joists.

Contractor Pricing Available
Contractors can request contractor pricing or call 804-798-3605 to discuss product availability, bulk orders, and pickup locations.
