HOW DOES IT WORK?
WHAT IS INSULATION?
Insulation acts as a barrier to heat loss and heat gain, particularly in roofs and ceilings, walls and floors.
Half of the energy we use to heat or cool our homes can simply leak out without insulation.
Insulation helps to:
save money on your energy bills
reduce your energy use and lower greenhouse gas emissions
reduce reliance on heating and cooling systems
improve your comfort at home.
There are several types of insulation you can choose from when building or renovating your home or place of business. EnergyLock offers open-cell spray foam insulation and closed-cell spray foam insulation. We insulate metal buildings, wooden buildings and non-vented attics.

SPRAY FOAM INSULATION
Spray Foam Insulation is designed to fill all cracks and crevices, is applied quickly and dries fast. It is mold resistant and can easily be applied to awkward spaces, such as around pipes.
There are two types of spray foam insulation – open-cell and closed-cell.
Less expensive, creates an excellent sound barrier, typical R-value of 3.5 to 3.7 per inch, perfect for interior walls
Creates an air tight barrier, typical R-value of 6 per inch, perfect for attics and exterior walls, creates a moisture barrier
There are two types of foam-in-place insulation: closed-cell and open-cell. Both are typically made with polyurethane. With closed-cell foam, the high-density cells are closed and filled with a gas that helps the foam expand to fill the spaces around it. Open-cell foam cells are not as dense and are filled with air, which gives the insulation a spongy texture.
The type of insulation you should choose depends on how you will use it and on your budget. While closed-cell foam has a greater R-value and provides stronger resistance against moisture and air leakage, the material is also much denser and is more expensive to install. Open-cell foam is lighter and less expensive but should not be used below ground level where it could absorb water. Consult a professional insulation installer to decide what type of insulation is best for you.
