Spray Foam Insulation Explained

When it comes to getting homes insulated against heat and cold, keeping the indoor temperature comfortable and ensuring reduction in energy bills and carbon footprint, Spray foam insulation can be the best choice. Read and know which Spray Foam Insulation is best, and what exactly is this type of insulation. 

What is Spray Foam Insulation?    

Spray Foam Insulation is a type of insulation material that happens to be used commonly for the purpose of insulating homes across the world, and especially in countries like the UK. Spray foam insulation is composed of a blend of polyurethane and isocyanate – which are two composite materials. An equipment of special form is used for this kind of mixing. A heated hose sprays this mixture onto surfaces which have to be insulated – such as attics, basements, lofts etc.

Types of Spray Foam Insulation

Spray Foam Insulation can be found in two different types:

·         Open-Cell Spray Foam Insulation

·         Closed-Cell Spray Foam Insulation

The main difference between the two types is the fact that foam cells in the latter are spaced nearer than in the Open-Cell variety. In the Closed-Cell variation, the foam cells are actually pressed together. This helps prevent the entry of air and moisture in a much better way. Both forms of insulation can be a great alternative for standard fiberglass insulation. Which Spray Foam Insulation is best is easy to understand. The Closed-Cell variation ensures better insulation.

Why Consider Spray Foam Insulation?

Spray foam insulation offers better air sealing and insulation, and is more effective during effectiveness. This is among the commonest types of loft insulation materials that can offer a better level of insulation around the windows. 

This kind of insulation material does not attract mold, and unlike metal or wood, it does not rot, rust or deteriorate. When foam insulation is sprayed properly on an area, it does not become a mold colony, food source or a great place for molds to thrive in. It is ideal for setting or spraying on areas such as basement, garage and attic.

It can serve as a perfect sealant, and can ensure an air sealing to take care of all the bad cold spots and uncomfortable drafts. Spray foam can work as an air barrier and an insulator. Spray foam insulation has many more advantages, and it can dry out quickly. You do not have to get it replaced even when it gets soaked or wet. If you can spend more, and go for the Closed-Cell variation of Spray foam insulation, you can be assured of better insulation.

Spray Foam Insulation Costs and Savings

Keep in mind that while square foot measures area, board foot measures volume. 1 board foot means 1 sq. foot with a thickness of 1-inch. Per board foot of open cell spray foam loft insulation cost has a cost in the range of $0.44 to $0.65. Typically, the total average cost is in the range of $1,281 to $3,727. On an average, about $2,474 is charged by most of the contractors out there. 

Closed-cell foam has a higher cost. The cost per foot is around 1 to 1.5 USD. However, it is suggested to be used in homes located in places with harsh climate. It might be more expensive than the Open-Cell variety, but the higher cost is justified by the fact that it extends a higher level of insulation.
