In recent years, spray foam insulation has become an increasingly popular way to insulate properties throughout the UK. But what are the benefits compared to other traditional methods?
Less is more
Traditional insulators include mineral/glass-wool, polystyrene slabs and expanded polystyrene. People don’t tend to insulate their lofts with these products due to the desire to have more loft space.
The required thickness of 270mm of loft insulation is higher than the joists, meaning that you can’t lay boards over the top for support. However, 100mm of spray foam insulation is equivalent to 170mm of loft insulation, according to the National Insulation Association. Spray foam insulation is a great alternative as you need less for the same insulating effect.
It’s also worth considering if you have hard to treat cavity walls or solid walls that aren’t suitable for external insulation due to planning restrictions.
Support your property
Some forms of spray foam insulation sets rigid, so can be used to help support roofs that are suffering from nail fatigue (when the nails used to hold slates in place rust) or support cavity walls where the wall ties are failing (causing cracks and bulges in walls).
Spray foam insulation can also be waterproof as well as breathable. Making this type of insulation ideal for properties that are prone to floods.
Because spray foam insulation is such an effective insulator, those who have it installed have found that they have saved a considerable amount on their energy bills. It has shown to provide energy savings at an average of 50% or more, compared to other types of insulation that average around 30%.
Spray foam insulation can be more expensive than other insulators, and you’ll need to get a specialist installer to fit it. But it’s an investment that will improve your home in the long run.
