Closed Cell Spray Polyurethane Foam Insulation

Why choose close cell spray foam?

Spray polyurethane foam (SPF) insulation helps keep homes warm in the winter and cool in the summer. Because it is sprayed directly into the gaps, cracks and other surfaces that contribute to heat loss, it both insulates and air seals, offering one of the easiest and most effective ways of weatherizing existing homes and new construction. When installed following proper safety and handling guidelines, spray polyurethane foam can help...

Spray Foam Residential Applications

  • External Walls
  • Internal Walls
  • Ventilated Attics
  • Unventilated Attics
  • Vaulted Ceilings
  • Interior Surface Basement Walls
  • Exterior Surface Basement Walls
  • Under Radiant Heat Concrete Slabs
  • Radiant Heat Cavity Sealing
  • Rim Joists

Help save on energy bills*

  • The U.S. Environmental Protection Agency estimates (for all insulation) that homeowners who air seal and insulate their homes can save up to 20% of heating and cooling costs (or up to 10% total energy costs). (Source: Energy Star)
  • SPF resists heat transfer better than many other insulation materials, with R-values typically in the range of 3.5 - 6.5 per one inch of thickness. R-value is a term used to rate an insulation's ability to resist conductive heat transfer. The higher the R-value, the more effective the insulation's ability is to reduce conductive heat flow.
  • Because SPF insulation minimizes air infiltration, it assists in preventing moisture vapor from entering and escaping the home, which in turn reduces the load on heating and cooling systems.

*Savings vary. Find out why in the seller's fact sheet on R-values. Higher R-values mean greater insulating power.

Reduce drafts, noise and increase comfort

Areas to Sprayfoam
  • SPF is an effective air barrier.
  • SPF is commonly used to prevent drafts from windows, doors, attics and floor boards creating a more comfortable indoor environment.
  • SPF helps minimize air-borne sound transmission.

Minimize air infiltration that can generate condensation and result in mold growth

  • Moisture and humidity inside the home can lead to mold growth. Gaps and cracks in the building structure and condensation on windows can keep the humidity high and support mold and mildew growth. Left unchecked, mold and mildew can cause wood to rot. Air sealing the gaps between the attic and living space can help manage moisture and humidity issues.

Seal small cracks to insulate large areas, such as walls and roofs

  • Because SPF is spray-applied on site, it can more easily insulate and seal the small cracks common in homes.
  • The application also makes expansive surfaces - like walls, attics and roofs - easy to cover in a relatively short amount of time.
  • Applied to the exterior surface of basement walls, SPF not satisfies insulating requirements but serves as an excellent water sealer as well.

Resistant to settling and adds structural integrity to structure

  • Typically not subjected to structural deterioration/decomposition and resists settling
  • Due to the rigidity and expansion properties of the closed cell polyurethane faom, it actually helps the framing to resist movement and racking.
