Calgary spray foam is the option of choice for most homeowners. This is not because it is cheap but mostly for its effectiveness in insulation. Although the initial cost may be a tad high when compared with the likes of Fiberglass batts, spray foam offers more savings than any other material available on the market. But why is it so effective? In this post, we will be looking at some of the things that make SPF an effective insulation material.
Fiberglass has a low R-value of less than 3.0 per inch of thickness. You have to stack more batts to achieve the recommended R-value. This is the primary reason that makes fiberglass a bad choice when insulating tiny crawl spaces and other hard to reach spaces such as around plumbing. Spray foam Calgary, on the other hand has a high R-value of more than 6.0 per inch of thickness. This means you don’t need to apply too many layers to achieve the desired R-value. The high R-value further prevents heat transfer which is a common cause of heat loss/gain in homes.
Even after you achieve the desired R-value in insulation, if you don’t seal all the gaps that air can pass through, the end results will not be as impressive. This is the case with fiberglass batts. They don’t create airtight seals. Air infiltration is common and it accounts for up to 40% of heat lost/gained. SPF, on the other hand, creates airtight seals. During installation, the foam will expand and adhere to the surfaces it is applied on before it cures. This is one of the key reasons why it is effective in creating airtight seals. It creates air and water/vapor barriers.
Easy to insulate tricky areas
As aforementioned, when it comes to the use of a solution with a low R-value, you will need to apply several layers before you can attain the recommended R-value. Closed-cell spray foam has a high R-value. This means you don’t need to apply many layers in insulation. What is more is that with Calgary spray foam, you don’t necessarily need to disassemble the walls or ceiling in order to insulate the area behind the walls. The spay foam contractors Calgary can drill holes through which they inject the foam into the desired area. This is one of the key reasons why SPF is effective in insulating difficult to insulate areas such as area around plumbing and in tiny crawl spaces.
You should also note that the long lifespan of spray foam Calgary is another reason why it is so effective in insulation. With time, fiberglass batts will start to sag and settle. This means spaces will be left that allow air infiltration. This is not the case with polyurethane Calgary. SPF has a long lifespan of more than 30 years and it does not sag or settle.
These are the key traits that make Calgary spray foam effective in insulation. All that you need to do is to hire the most experienced and competent spray foam contractors Calgary to help with the installation.
