SPRAY FOAM INSULATION FAQs
Q: WHAT IS SPRAY POLYURETHANE FOAM?
A: There are two types of polyurethane foam material we offer, Half pound open cell SPF and Two pound closed cell SPF.
1/2 Lb. (Open cell SPF)
This product uses air pockets to help achieve its R-value. Better than fiberglass but still requires a vapour barrier. There are many uses for this product such as Rim joists pockets, Garage ceilings for a room above,
2 Lb. (Closed cell SPF)
This product when installed at 2" thickness will not require a vapour barrier on any substrate. No other insulation has a higher R-Value and can guarantee its Long Term Thermal Rating when installed by a certified Spray Foam technician.
COMMON USES FOR SPRAY FOAM INSULATION?
Q: WHAT IS SPRAY FOAM?
- wall and ceiling insulation
- attic insulation
- sound barrier between walls/floors
- foundation wall insulation
- prior to pouring basement concrete floor
- 2 lb SPF will insulate and create a perfect seal to protect from Radon gases.
- HVAC systems to seal all gaps and cracks for the highest efficiency
A: Spray Foam (Spray Polyurethane) is the result of two liquids mixed together. Isocyonate and a resin are mixed using special equipment to regulate pressure and heat. Both fluids are stored separately until they meet in the end of the gun used to apply them. There are 2 types of spray foam typically used being open cell and closed cell.
Q: WHAT IS R-VALUE?
A: R-Value measures the thermal resistance of a material. The larger the number, the longer it takes to for temperature to go through it (R-20 is 2x better than R-10)
Q: WHAT ARE THE BENEFITS OF USING SPRAY FOAM INSULATION OVER STANDARD FIBERGLASS BATT INSULATION??
A: The biggest downside to fiberglass insulation is that its Long Term Thermal Rating (LTTR) is greatly reduced over time. The printed R-Value on a bag of fiberglass insulation is not always the end result. When installed "perfectly", Fiberglass insulation should meet the R-Value on the bag. The reality is its actually about R-12 due to many imperfections such as framing, sagging, gaps, electrical, plumbing, etc. For every 1/8" gap in your fiberglass insulation you will lose about 40-50% of the R-Value. With Spray Foam Insulation installed by The Spray Foam Guy you will never have to worry about losing any R-value.
Q: WHAT IS LONG TERM THERMAL RATING (LTTR)?
A: This is a rating system to test the performance of insulation long term (2 years+). Typically the R-Value is based on the R-Value on the bag of fiberglass or immediately after installation. Make sure to ask what the LTTR is of your insulation being installed. This will give you a true value of your investment with Spray Foam insulation being installed in your home.
Q: HOW MUCH DOES SPRAY FOAM INSULATION COST?
A: With all the government grants, rebates, and incentives, spray foam insulation is more affordable than you would think.
