Spray foam Calgary is a newer option in home insulation. This is why the majority of homes across the globe are insulated using air-use insulator; fiberglass or cellulose. These used to be effective solutions. However, now that we are in the age of the spray foam, these are outdated insulation options. This is more so because they don’t create airtight barriers, they are water permeable and they will settle or sag after a couple of years. This does not happen to SPF. These are one of the key reasons why it has gained immense popularity across the globe.
So, why should you retrofit an existing home with polyurethane Calgary?
The first reason is because of the high R-value of spray foam. Consider insulating the attic with cellulose or fiberglass which can achieve an R-value of R-30. As impressive as this may seem, the R-30 can easily be exceeded. It will only take a few hours for the heat from the attic to build up to 140 degrees and exceed the R-30. Within no time, this heat will start heating up your house and running up your energy bills. The condition will even be worse if the HVAC is in the attic. This is not an issue with Calgary spray foam.
Closed cell-spray foam has an R-value of more than 6.0 per inch of thickness. This means you can achieve more R-value without having to use too much material.
When retrofitting existing homes, homeowners focus more on where their money will be most well spent. The roof area will take up even more than 35% of the energy that is needed to cool and heat the home. The crawl spaces, on the other hand, will take up to 30%. The windows, doors and the floors will consume the remaining percentage. These are all problem sites that can be covered using polyurethane Calgary.
With the right spray foam contractors Calgary, you will be able to cover the entire building envelope. The best thing with SPF is that it can be installed virtually anywhere. You can apply it under the roofing systems, in tiny crawlspaces and other difficult to insulate areas. What is more is that the solution not only has a high R-value but will also prevent air-infiltration.
Spray foam Calgary will prevent heat loss/gain in many ways. At the end of the day, the HVAC will not have to work overtime in summer or winter. The installation of SPF can bring an energy saving of up to 30% and more. Statistically, the energy saving of installing spray foam is 3 to 7 years.
Polyurethane Calgary is a great option if you want to go green. All in all, you need to understand that this will not be your typical DIY project. You need expert help. You have to work with contractors who understand the properties of spray foam, ones with access to the right equipment and ones that understand your building envelope.
