The True Cost Of Spray Foam Insulation…
Spray foam is an insulation for the long term. Unlike virtually all other insulation products available to homeowners, one of the key benefits of spray foam is its durability. It won’t shrink, slip or degrade as time goes by and as testament to its performance, we guarantee it for a period of 25 years with the expectation that it will live with the life of the property into which it’s installed.
The physical performance with spray foam is shown through its air-tightness. When spray is applied between roof rafters, underfloor or in walls, it expands to completely seal into the void. This makes it an air-tight insulator and it can reduce heat loss by up to 95% in comparison to having no insulation at all.
In terms of its actual cost saving, spray foam can save up to 45% on energy bills where there’s no insulation in-situ. In circumstances where there’s already insulation in place, spray foam can save up to 22% or more dependent on the depth and condition of insulation already in place. These figures vary from property to property and on average, we’ve found spray foam to save an average of 32% on heating costs giving it a pay back of between 4-6 years.
What does spray foam insulation cost?
Dependent on the size of your property and the condition of the substrate onto which spray foam is installed, the costs will vary as will the type of spray foam insulation that we can specify. When we are giving a price for ThermoFoam we are able to use the benefits of technology to find your property of Google Earth and from there we can use the Google measuring tool to provide a fairly accurate roof size.
The average UK residential property has a roof area of approximately 76 square metres and the determining factor of the cost of spray foam will depend on:
- Is there a roofing membrane?
- What condition is the membrane in?
- Is the membrane breathable or non breathable?
- How accessible is the entire roof area?
- Are the roof rafters in good condition?
- Are there signs of damp, mould or condensation?
- What’s the condition of the physical roof?
- What insulation is already in place?
A property survey is usually the best way for us to answer the above questions to determine whether your property is suitable for ThermoFoam and if so, whether it’s open-cell or closed-cell.
Open cell is less thermally efficient than closed cell which is why we apply at roughly double the thickness to maintain thermal performance. It’s lower in cost than closed-cell and is typically quicker to install, boasting the added benefit of a great barrier against sound transmission – beneficial if you live on a noisy street or under a flight path.
Closed cell is a high density insulator that offers exceptional thermal performance per inch whilst helping to stabilise the roof structure and providing a barrier against moisture ingress. Closed-cell can be applied direct to tile in circumstances where there is no roofing membrane of the roof tiles require bonding to prolong their life.T
It’s important to remember that spray foam is unlike any other insulation product. It offers premium, lifetime performance and is not made from cheap materials. Spray foam products should be installed by experienced technicians to maximise the benefits of the application. Once installed, the average saving of spray foam will be around 32%* against the costs of heating your home.
With the average UK home spending £676 on heating costs per annum, you should expect to see a payback within 4-6 years* and you will enjoy the full benefits of spray for at least 25 years. Your first step to taking control of your energy costs is to book a free, no obligation survey of your property to establish whether it’s suitable for ThermoFoam.
