Lightweight, Effective Residential Roof Insulation

Don't Let Your Heating Costs Go Through the Roof.

Insulfoam residential roofing products, such as the ENERGY STAR® certified R-Tech lightweight rigid insulation panels, offer a versatile, all-in-one thermal solution for roofing projects. 

Gone are the days of fiberglass splinters, loose slivers, and other insulation products that are difficult to cut and/or require excessive material to provide adequate coverage.  Builders can quickly and economically increase a home’s insulation power with these large lightweight panels that can be easily cut to fit virtually any space. Our products are mold and insect-resistant and backed by a 20-year, 100% thermal performance warranty.

EPS insulation panels are available in standard sizes and deliver excellent dimensional stability and compressive strength.  Use EPS insulation to:

  • Support new or retrofit insulation projects
  • Increase thermal efficiency
  • Minimize air leaks from the rafters
  • Lower heating and cooling costs

Insulfoam’s EPS Roofing Insulation products are available in 4' x 8' sheets with thicknesses from 3/8" to 5" in 1/8" increments, and a range of densities (10-60 psi). Fanfold panels are also available, enabling you to cover large areas quickly (imagine unfolding 100 squares of insulation in minutes). All without the loose fill mess or the irritation of fiberglass.

Residential Wall Insulation That Reduces Energy Costs

Wall-to-Wall Insulation

Cooling and heating systems shouldn’t work overtime to compensate for inadequate insulation. Instead, use Insulfoam Wall Insulation products in your continuous insulation (ci) plan to increase thermal efficiency and create a more comfortable home environment.

Residential Wall Insulation Benefits and Applications: 

  • Use in exterior, interior, and cavity walls, siding underlayment, insulating sheathing, continuous insulation sheathing, or weatherproofing protection barrier.
  • Upgrades the thermal insulation value of exterior walls under many types of exterior finishes.
  • Provides a solid, level base for new siding while helping to minimize air leaks.
  • Adds thermal resistance to interior basement walls.
