Calgary Spray Foam – How to Pick the Best Calgary Spray Foam

Calgary spray foam has become the ideal choice for persons who want to completely insulate their homes. The option also offers a number of other benefits among them improved structural strength, flood control, reduced air infiltration among other things. However, when it comes to the installation of SPF, homeowners are faced with the challenge of selecting the best foam for their project. If you are one of those people, this post is designed for you. To be able to pick the right foam, you have to understand the pros and cons of each option.

Open cell SPF
The first option you will be provided with by spray foam contractors Calgary is the open cell spray foam. This is the less dense option. It is much cheaper when compared with closed cell spray foam. Open cell SPF is permeable to moisture but impermeable to air. It is important to under these traits before you consider open cell for your project. You should also note that it has a lower R-value per inch (about 3.6) so you have to apply a thicker layer to achieve a desired R-value. When the objective is insulation, you will need to apply a thicker layer. The option might be viable if the framing members are deep enough to accommodate the desired R-value.

Open cell spray foam Calgary is preferred by green builders. This is because it uses water as the blowing agent. The blowing agent used in closed-cell SPF has a high global warming potential.

Closed cell SPF
Closed cell foam, on the other hand, is preferred because of its insulation properties. It performs much better than any other insulation available on the market. It is impervious to moisture, and also effective as a vapor retarder.  The closed cell foam can also be used under slabs, above or below grade walls, in the ceilings and in roofing.

Because of the high density and the glue-like tenacity, spray foam contractors Calgary recommend closed cell foam. It adds structural strength to the ceiling, roof assembly and wall. The disadvantages of closed cell foam include the high initial investment and the blowing agent which has a major global warming potential.

The two are the main qualities of the two types of polyurethane Calgary. Your choice will mostly depend on what you want to achieve. For example, if your goal is to soundproof a room, you need to focus more on open cell SPF. Its qualities make it an ideal choice for noise absorption. Closed cell-spray foam, on the other hand will be ideal if your objective is mainly to add structural strength and where there is not enough room for installing thicker layer of SPF.

Liaising with spray foam contractors Calgary is the key to finding the best spray foam for your needs. Make sure that you clearly explain your needs to the contractor so that he can pick the foam that will meet your project needs. The contractor will further give you advice on alternative options and how you can use the available options to achieve your desired goals.
