Spray Foam Insulation

Spray Foam Insulation

Spray foam insulation is a two-component mixture made of isocyanate and polyol resin. These two properties combine at the tip of a spray nozzle and form an expanding foam that can be sprayed onto concrete slabs, roof tiles, into wall cavities, or through holes drilled into the cavities of a finished wall. 


Spray Foam Advantages

The US Department of Energy found that 40% of a home’s energy is lost through air leaks — driving up your utility bills. However, buildings that take advantage of spray foam insulation are insulated up to 50% better than traditional insulation products. Spray foam can be used to fill gaps and stop the leaks in many areas of a home or building. Some common spots for air leaks that can be sealed with spray foam include:

  • Behind knee walls
  • Attic hatches
  • Wiring holes
  • Plumbing vents
  • Open soffits
  • Recessed light, furnace flue or duct chaseways
  • Basement rim joists, windows and doors
  • Walls
  • Roofdecks

Spray Foam Types

Spray foam insulation is provided in both high pressure and low pressure systems. High-pressure is most often used in new home construction, whereas the low-pressure spray foam is used mostly for remodeling jobs where existing walls already have drywall. Spray foam insulation is categorized by two types: open and closed cell.

Benefits of open cell insulation:

  • economical
  • provides a good air barrier (but no water vapor barrier)
  • R-value of 3.4 to 3.8 per inch
  • excellent for sound control

Benefits of closed cell insulation:

  • acts as water vapor and air barrier
  • R-value of 6 per inch
  • adds structural integrity to your home
  • can be used as stand-alone and hybrid insulation
