Regardless of whether looking to insulate a brand new building or retrofitting an old one, homeowners are finding spray polyurethane foam or SPF as an increasingly viable option. Essentially a spray applied plastic; it can form a continuous insulation as well as a complete air sealing barrier on walls, corners, and all contoured surfaces. In this process, unique liquid contents are mixed and reacted chemically together and quickly to expand on contact and form the foam to provide the necessary sealing and moisture barrier. This form of insulation is highly preferred not only because of its extremely commendable resistance to heat transfer but also because of its exceptional ability to reduce unwanted air infiltration through any joints, cracks or seams.

Spray foam insulation is primarily of three types and used for specific purposes. They are -

• High-density SPF which is predominantly used for exterior and roofing applications.

Each type has its own unique advantages and normally an SPF contractor takes into account, the building, climate, project, budget, etc. and suggests the best option to go for. Apart from the structure of the foam, its method of delivery and installation also plays a critical role. It is also of three types i.e. high-pressure as well as low-pressure, two-component foam and insulating foam sealant.
