Services
Under Concrete Insulation
Our polyiso rigid foam insulation provides exceptional thermal performance under concrete slabs and flooring. With 40+ years of proven durability in heated floors and refrigerated warehouses, it maintains structural integrity under heavy loads. The R-6.5 value per inch outperforms alternative materials while resisting moisture absorption.
Attic Insulation
High-R-value polyiso boards create energy-efficient attic spaces by preventing heat transfer through ceilings. Custom-cut panels fit between joists while foil-faced options enhance radiant barrier performance. Factory-second pricing makes whole-attic upgrades cost-effective for residential and commercial properties.
Basement Insulation
Rigid foam boards provide permanent thermal protection for basement walls and floors. The moisture-resistant material bonds securely to concrete surfaces using construction adhesive. Available in multiple thicknesses to meet specific insulation requirements for finished or utility basements.
Garage Door Insulation
Polyiso boards reduce energy loss through un-insulated metal garage doors. Custom-cut panels fit standard door dimensions while maintaining operational clearance. The high-performance insulation helps regulate garage temperatures and improve overall building energy efficiency.
Metal Building Insulation
Specialized insulation solutions for metal structures prevent temperature fluctuations and condensation issues. Polyiso boards installed in walls and roofs create energy-efficient pole barns while reducing noise transmission. Available in standard 4'x8' sheets for easy installation.
Questions
What makes polyiso insulation better than other types?
Polyiso offers R-6.5 per inch compared to R-5 for XPS and R-3.8 for EPS. It resists moisture absorption, maintains performance under compression, and creates effective air seals with foil tape.
Can your insulation handle heavy loads?
Yes, our polyiso boards have supported semi-trucks on concrete floors and maintained integrity in refrigerated warehouse foundations for over 40 years.
What thickness should I choose for my project?
Thickness depends on application: 1/2"-2.5" for cavity fill, 3/8"-4" for full sheets. Consult our product specifications or contact us for application-specific recommendations.
Are these factory-second products lower quality?
Factory-second boards meet all performance specifications but may have minor cosmetic imperfections. They offer identical thermal performance at significant cost savings.
How do I install polyiso insulation?
Cut to size with a utility knife and install using construction adhesive for concrete surfaces. Use foil tape to seal seams. Detailed installation instructions accompany all orders.
