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.
There are two types of spray foam insulation:
Both are usually made from polyurethane and filled with bubbles of gas or air, but have different properties when they set.
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.
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.
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.
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.
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.
