Spray Foam Insulation – the benefits

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.

Energy savings

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.

Sound Insulation

We have been installing warmcel blown fibre insulation as a solution to suppress noise for over 10 years. On many occasions it is part of an overall design that enables noise to be suppressed across a whole range of frequencies.

Acoustic floors

When noise is coming up from below warmcel 500 blown into the floor void at the appropriate density can be extremely effective at reducing this noise on its own.

High level of airborne nose suppression
Very quick to install (up to 60 square metres each day)
Minimum disruption as whole floor does not need to be taken up. 1 or 2 floorboards per room.

Warmcels performance can be enhanced in this situation by using a selection of membranes or acoustic mats.

Acoustic ceilings

When noise is coming from the ceiling it is normally a mixture of airborne and impact noise; there may also be an element of flanking path noise.

Warmcel 500 is blown into the ceiling void at the designed density. The effect of this measure is to soften the various noises that come into your property. This means that any additional measure will be more effective. Details and costs of these measures can be found at www.

Again it is quick to install.

There are design issues to look at such as recessed spot lights, which can either be changed for lights which emit very little heat or acoustic light boxes can be constructed around them.
