Seal It From the Bottom Up

Crawlspaces and under-insulated basement areas can experience issues such as energy loss, temperature variations, moisture problems, poor indoor air quality, structural damage, and pest infestations. Proper insulation is crucial to address these issues.  Due to its ability to create an airtight seal, resist moisture movement, and provide high thermal performance, closed-cell SPF is a superior choice for insulation in these areas, greatly reducing heat loss and energy consumption, while lowering utility costs. 

Benefits of Insulating Basement and Crawlspace Areas:

  • Helps reduce moisture transfer and build-up, which reduces risk of mold and mildew growth

  • Seamless application creates a seal to prevent air and moisture movement, reducing energy needed to heat, cool and dehumidify the space
  • Creates a more comfortable, energy-efficient indoor environment with high insulating values
  • Improves indoor air quality by reducing the amount of allergens, pests and pollutants entering the building

WALLTITE®

WALLTITE® is a high-performance, closed-cell spray polyurethane foam (SPF) insulation that creates a seamless insulating air barrier to help improve the energy efficiency, comfort, and durability of homes and buildings. Spray-applied as a liquid, WALLTITE® expands and adheres to most substrates, flowing into cracks, joints, and hard-to-reach areas to form an airtight seal. Its closed-cell structure also adds rigidity and can help reduce air leakage and moisture intrusion, supporting long-term building performance. WALLTITE® easily seals corners and transitions, as well as areas around pipes, wiring, and other openings.
