Spray foam Calgary continues to amass immense popularity across the globe. This is the insulation material of choice for both residential and commercial buildings. It is also used in other areas such as insulating tracks. However, before you go ahead and start installing this material, it is important that you understand the two types of spray foam that are available: open cell and closed cell.
Calgary spray foam is categorized into two types: open-cell and closed-cell. Open cell SPF is lightweight and it is flexible and excellent as an air barrier. The open cell foams usually range from 0.5 to 0.7lb densities. These are also ideal for soundproofing. However, because of their sponginess and their lightweight, it is recommended to use this type of SPF on interior walls.
The second type is the closed-cell SPF. This has a higher density and is excellent in creating moisture barriers. Most of the SPFs that are used for insulation have densities that range from 1.7 to 2 lb. the density of closed-cell can go as high as 3 lb. in density. As a result, it can be used on exterior roof application and walls.
The main differences between open cell and closed cell are moisture permeability, flexibility and R-value. Closed cell foam has a higher R-value of more than 6.0 per inch of thickness whereas open cell-has an R-value of 3.5. Closed-cell is more compact which means it will be more effective as a moisture and air barrier than open-cell. Even so, both foams have their unique traits. You should not use their characteristics as the main determining factors but rather what you wish to achieve at the end of your project.
The best foam
Choosing the best polyurethane Calgary to use will depend on your application. It is not uncommon for some spray foam contractors Calgary to recommend open cell SPF in one project whereas others recommend closed-cell SPF for the same project. Always weigh your options prior to making a choice. You should also note that the building codes will also dictate your choice. This is more so when a higher R-value is needed.
These points will definitely make it easier for you to decide on whether to use open cell or closed cell spray foam Calgary. If you are confused, you can always seek expert advice from spray foam contractors.
