Calgary spray foam offers more than insulation benefits. The benefits range from added structural strength to moisture control to a significant reduction in air infiltration and then some. With a simple Google search, you will find a lot of information on the benefits of SPF. However, it is important to note that the benefits are often generalized. If you plan on installing SPF, you should start by understanding that there is both open cell and closed cell SPF and that the two offer their own unique benefits. In this post, we shall be distinguishing the two.
Open cell SPF
Open cell spray foam Calgary is not as widely used in home insulation. The reason for this is because of its low R-value. It has an R-value of 3.5 to 3.6 per inch of thickness. This means that its insulation benefits are the same as those of fiberglass and cellulose materials. The key reason why people go for this option is because it is cheaper and offers soundproofing benefits.
When comparing open cell to closed cell, you will notice that open cell has a lower density. It is also vapor permeable. It is also good to note that this solution uses carbon dioxide or water as the blowing agent. You will even be able to find open cell polyurethane Calgary that is made using bio based materials such as soybean oils instead of petrochemicals. All the same, open cell SPF will be able to create air barriers but it is not as effective in creating water barriers. Open cell SPF can only be used on interior walls.
Closed cell SPF
This is the most widely used type of Calgary spray foam. It has a high R-value of more than 6.5 per inch of thickness. Although it is more expensive than cellulose, fiberglass and open cell SPF, closed cell SPF is worth the investment. You will be able to recoup your installation expense within no time thanks to its effective ability to reduce heat loss/gain by more than 40%.
In addition to the insulation benefits, the solution will create air barriers, moisture/water barriers, keep pests out, add structural strength and do so much more. In areas prone to high winds, spray foam contractors Calgary recommend using closed cell SPF under the roof so as to prevent wind uplifts. The best thing is that this solution will serve you for more than 30 years.
Deciding on whether to use open cell or closed cell SPF will depend on the nature of your project. What do you want to accomplish at the end of the day. If your interest is in soundproofing, open cell SPF will be the perfect choice.
