Everything You Need To Know About Spray Foam Insulation
Spray foam has become one of the most preferred since the late 1990s, due to its effectiveness. It has expatriated even conventional insulation materials such as fibreglass batts, displaying a grander R-value per inch and air-sealing capability. But how come is everyone not using spray foam if it is that good?
Why Spray Foam Should Be Viewed As The Insulation Material Of The Future
For many years, the conventional insulation for businesses and homes included products like cellulose and fibreglass since they are affordable to install. Even though they are effective, they can retain and absorb moisture, resulting in dampness that can cause mildew. Besides that, their porous surfaces can cause leaks that render air conditioning and heating equipment inefficient. Instead of wasting money on constant maintenance and repairs, why not op for a more efficient product such as spray foam?
More About Spray Foam
Spray foam or SPF is an insulation type which is made from plastic or polyurethane foam. It is especially adaptable, and the mixture can easily adjust to any customer’s requirement. Spray foam has a semi-solid consistency that makes it highly suitable for roofing, pipe work and other solid structures. Despite it being sprayed in liquid form, the foam is non-porous and flexible, which is why it is useful for wall or roofing insulation purposes. Due to it being so lightweight, it is used for flotation for boats, docks, and ships as well. Spray foam is durable enough to be used for various industrial applications from structural strength of aeroplanes to walk-in freezers. If you require all seasons insulation, then spray foam is a highly viable choice.
In Which Areas Are Spray Foam Utilized?
Spray foam can be used for industrial and domestic purposes. Spray foam insulation is perfect for any type of building, large transport, and refrigerated units. It has been used effectively for flotation devices, insulation material for venues like spas, theatre sets and movies as well as adhesive for construction.
What Are The Types Of Spray Foam?
Closed Cell Polyurethane Spray Foam Insulation
This kind of spray foam insulation is generally viewed as the best type since various cells that is making up the foam are condensed onto themselves. They are nearly impermeable to moisture, which means you will not have to worry about mold issues. There are a number of spray foam varieties of which everyone has a slightly variable R-value. Foams which are exceeding 24kg is generally considered as closed cell whereas anything under is open cell foam.
Open Cell Polyurethane Spray Foam
This kind of spray foam insulation is becoming the most favoured type for residential uses such as roof insulation, underfloor insulation, and wall insulation since it is much more cost-effective than closed cell spray foam but offers the same benefits. There are a few variances, however. The difference between closed and open cell foam is that the open cell foam possesses a lower R-value per inch and subsequently necessitate a higher volume of foam inside a cavity to adhere to code requirements. Once applied appropriately, the energy savings for open cell foam is the same as those from closed cell foam. Irrespective if you are choosing closed or open cell foam, you will still have an airtight building that permits for excellent energy efficiency.
