What is polyurethane spray foam insulation?

Polyurethane spray foam or in short SPF, is a foam that is used for insulation of the roofs, walls, around corners and on all surfaces that have contours. Polyurethane spray foam insulation is being performed in many homes across the country. Canadian Urethane Foam Contractors Association has made an estimate that this type of spray foam is installed in around 400,000 houses in Canada. Every year the number of homes that insulate their house in this way grows by 40%.

This type of foam was developed for military airplanes and it was used in 1940s. It gained its new function in the 1970s, when people started using it in homes.

Polyurethane spray foam is usually called as a two component foam as it uses two components that are mixed on the site where the insulation is performed. It is important that you hire a professional for this type of upgrade on your house as the mixture must be done by the book to avoid cracks or unfilled voids.

There are two types of polyurethane spray foam insulation: open-cell and closed-cell spray foam insulation. The tiny cells in the open-cell spray foam are not completely sealed. Less chemicals are used in this type of foam and for that reason it is more affordable. As it is not completely closed it is not so resistant to moisture. When it comes to air, it represents a good barrier. Its main use is for interior walls as a sound barrier.

The density of the closed-cell spray foam is much more higher and for that reason it offers a great protection against moisture and vapour. It can be applied anywhere in the house as it is good for outdoor application, roof application and for interior walls. The cells in the closed-cell spray foam are much more closed and that allows the foam to be applied on any surface.

Open-cell and closed-cell foam have different R-values. Closed-cell spray foam has higher R-values and for that reason it has higher insulation properties.

There are many benefits of having a polyurethane spray foam insulation. The main reason why people decide to install this type of insulation is to save on energy bills that can be very high if your house leaks air. There are also health problems that people are experiencing due to mold and vapour like allergies. Mold can be fought and prevented with the proper insulation of the spray foam. If you have mold in the house, it is more likely that the wooden parts of your house will rot causing you unnecessary costs.

Spray foam can create a very efficient sound barrier and in that way you will be free from the outside noise or traffic. You will also be able to listen to the music more loudly or perform any other activity that is loud without disturbing the neighbours.
