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
