HOW LONG DOES IT TAKE TO INSTALL SPRAY FOAM INSULATION?
Installing spray foam insulation is a fairly quick process. A typical house can be fully insulated in a day or two. Large houses, or houses with unusual design features may take slightly longer. Smaller projects, such as attics, crawlspaces, etc. may take only a day.
IS SPRAY FOAM INSULATION WORTH THE MONEY?
The overall lifetime energy savings of installing spray foam compared to traditional fiberglass far outweighs the cost difference in the short term. Cost savings are usually recouped within 5-7 years.
WILL INSTALLING SPRAY FOAM INSULATION SAVE MONEY AND ENERGY?
Installing spray foam insulation will absolutely save on your fuel and electric bills. Although the installation costs are slightly higher than fiber or cellulose, this is quickly offset by ongoing savings. Studies indicate that homes insulated with foam use between 20% to 40% less energy than homes insulated with traditional techniques.
WHAT IS THE R-VALUE OF 2″ OF SPRAY FOAM INSULATION?
Depending on the manufacturer, the R-value of 2″ would be 12-14.
HOW DOES SPRAY FOAM INSULATION COMPARE TO BLOWN-IN CELLULOSE OR GLASS FIBER BATTS?
Blown-in cellulose will only slow down leakage, while spray foam will stop leakage all together. Cellulose only has an R-value of 3 to 4, while spray foam insulation has an R-value of 6.5 to 7 (measured at a 1 inch application for both). Glass fiber also will not stop air leakage, only slow it down. Glass fiber batts have an R-value of only 3.5 at 1 inch thickness. Both glass fiber and cellulose will sag or settle over time, leaving sections of your home uninsulated. Only spray foam insulation creates a permanent barrier to heat loss and air entry.
HOW LONG DOES SPRAY FOAM INSULATION LAST?
Independent tests throughout the industry on properly installed closed cell spray foam indicates aged R-value has not decreased over 30-40 years.
CAN THE UNDERSIDE OF A ROOF BE SPRAYED WITH SPRAY FOAM INSULATION?
Depending on your substrate, most definitely!
WHAT HAPPENS WHEN SPRAY FOAM INSULATION GETS WET?
Closed cell spray foam will not absorb more than 10% of its weight. Open cell can absorb 100% of its weight.
HOW DOES THE HOME BREATHE?
When building a home it has always been a goal to eliminate air infiltration and exfiltration. We all know air brings in moisture, which causes issues such as mold and rotting of building materials. By using spray foam insulation you eliminate unwanted air penetration and exfiltration, providing a more energy efficient and comfortable home. By using Spf you stop 80% of your energy loss used to heat and cool your home.
As far as your home breathing, your hvac system exchanges enough air to provide non stale.
Your home only needs to “breath” to help keep traditional insulations and of building materials dry.
