Whether insulating a residential home or a commercial building, effective insulation is crucial for maintaining comfort, reducing carbon emissions and decreasing energy costs. However, when insulating a property, aiming for both efficiency and affordability can be a challenge.
With many types of insulation on offer, there may not be any one product that perfectly suits your needs – which is why combining different forms of insulation can be the perfect solution!
Wall insulation foam is often chosen for its excellent resistance to heat transfer, as it effectively plugs the gaps in walls. However, it can be expensive and requires professional installation.
Luckily, however, there is a solution: multifoil insulation.
Multifoil is an extremely versatile product; it can be used in residential or commercial properties, used in walls, floors or roofs, and applied as a standalone solution or in combination with other insulation products. When combined with insulating foam, multifoil can boost the performance of your insulation while also reducing costs.

Can multifoil insulation be used with another type of insulation?
Multifoil can be used either alone or in combination with other types of insulation to achieve maximum performance. In addition to wall spray foam insulation, multifoil can also be used with mineral wool, fiberglass, and other insulation products.
Boost the efficiency of wall foam insulation
While wall foam insulation is effective at preventing heat transfer, combining it with multifoil can help you maximise the amount of heat retained within the property.
At SuperFOIL, our multifoil has a radiant barrier which reflects warm air back into the room, preventing it from escaping the insulated space. This complements wall insulation foam’s conductive heat resistance, creating an excellent thermal barrier and protecting properties from extreme temperatures.
As well as providing insulation, SuperFOIL multifoil also incorporates either a breathable membrane or a vapour control barrier (depending on the type of multifoil) to reduce moisture and the likelihood of condensation.

Cost-effective way to boost insulation
Another drawback of wall insulation foam is that it is often expensive, especially if it is required in large quantities; spray foam for cavity wall insulation can cost as much as £20–£50 per square metre.
By combining foam insulation with multifoil, however, the overall cost of your project can be reduced. At SuperFOIL, our multifoil is highly effective even in just a single sheet – our SF60, the world’s highest-performing multifoil, achieves 4.42 R-values. This means that less is required overall to reach the target U-value for your project.
Additionally, because our multifoil is a 3-in-1 product (combining a radiant barrier, insulation and either a breathable membrane or vapour control layer) fewer additional products need to be purchased, bringing down the overall cost of insulating a building.
Easy and quick installation
Wall insulation foam requires a professional to install, further driving up the costs of your project. Installing multifoil is quick, easy and requires no specialist equipment or PPE. By supplementing foam insulation with multifoil, you can lower the cost of your overall project.
