WHAT IS SPRAY FOAM?
Foam spray insulation, also called spray foam, is an alternative to traditional building insulation that’s becoming increasingly popular in the UK. As the name suggests, spray foam insulation is a liquid foam which is sprayed into position and sets into an insulating layer. It can be used to insulate your roof, loft, walls, floors and more.
Types of Foam Spray:
There are two types of spray foam insulation:
- Closed-Cell Foam Spray
- Open-Cell Foam Spray
Both are usually made from polyurethane and filled with bubbles of gas or air, but have different properties when they set.
Closed-Cell Foam Spray
Closed cell spray foam sets into a rigid solid which can help support the structure of your property if it’s not in the best condition. It tends to be a better insulator than open cell spray foam. This is because when it sets, it contains lots of separate pockets of gas which slow down the movement of heat through it. But it’s a barrier to moisture, so you’ll need to make sure your room or loft is well-ventilated to stop condensation building up.
Open-Cell Foam Spray
Once set, open cell spray foam is less dense – you can compress it with your hand. So it can’t be used as a structural support. It’s not as good an insulator as closed cell foam, so you’ll need to install a thicker layer to get the same level of insulation. Open cell spray foam is often used as sound insulation as it blocks and reduces airflow. It allows moisture through it so there’s less worry of condensation building up.
WHERE DOES MY HOME LOSE ENERGY
Superior energy efficiency mostly depends on creating a better air seal. Wall insulation is a significant issue in home energy savings, but there are other factors that will lower home energy efficiency.
Doors and Windows
Water and moisture in the building envelope is the single, greatest threat to building durability in residential construction. In addition to causing building-durability issues, moisture can create ideal conditions for mold growth, which can dramatically impact occupant health.
Ceilings, Outer Walls Floors and Crawlspaces
Unsealed, responsible for about a third of the air leakage in a home. As much as 40% of energy loss is due to air infiltration. Therefore, the most effective way to improve energy efficiency and comfort in your home is to seal it with foam.
BENEFITS OF SPRAY FOAM
Spray Foam reduces energy bills by 45%. It airtights the building, blocking any heat loss and hence less energy bills
Spray Foam reduces mold and bacteria growth by sealing home completely, and making a home healthier
Due to complete airtight seal, Spray Foam improves buildings resistance to wind up lift by 300%
BLOCKS HEAT LOSS
Spray foam bonds together with building together making a airtight seal, which reduces heat loss and save energy bills
Spray foam normally weighs between 1.4 to 2.0 cubic foot and is very lightweight for roof structures and boats insulation
Spray foam seals joints end to end, and is made of Polyurethane/Polyisocyanurate, making it complete waterproof
