When it comes to multifoil insulation, the choice is just as simple. With a wide range of products out there, it’s easy to think that they are all the same, but this isn’t the case. Most multifoil manufacturers produce insulation that is between 30-40mm thick, however this doesn’t cater for every project type. SuperFOIL have a wide range of products you can choose from, ranging from 30mm, 45mm, 65mm and even 100mm, so you can be sure you are getting the right product for your needs.
To help make your decision easier, SuperFOIL and Roofing Supplies UK have written a post answering some of the more frequently asked questions that people have when it comes to multifoil insulation.
What type of projects can multifoil insulation be used for?
SuperFOIL insulation is suitable for all sorts of projects, from refurbishments to new build and everything else in between. Whether you are working on insulating your pipes, to insulating a shopping centre, we will be able to find you a solution that meets your needs. We are even use to problem solving for those individual projects that require some creating thinking when it comes down to insulation.
Can multifoil insulation meet building regulations?
Many people believe that multifoils cannot reach building regulations on their own. This is a widely held misconception that SuperFOIL love to challenge. Whilst some brands of multifoil cannot reach building regulations without the need for additional insulation, this is not the case when it comes to SuperFOIL. This is because of the wide range of high-performance products that we offer.
Here are just a few solutions we can offer using only SuperFOIL to meet building regulations in either a roof or wall.

Project Type |
Solution |
|
New Build Wall 0.18U-value |

|
Refurb/extension Wall 0.28 U-value |
As you can see, in these wall solutions, only one layer of one of our products is needed to meet either a refurbishment requirement, or a new build. With these solutions, NO additional insulation is required to meet building regulation U-value targets.

We also offer solutions using two SuperFOIL products to achieve the required performance. This is called a ‘duet’ installation. Again, using these solutions requires no extra traditional insulation to be added to meet the correct U-values.
It’s always vital to ensure you are meeting the correct U-value as required by building control. The experts at SuperFOIL are always happy to provide free of charge U-value calculations to ensure you find the best solutions for the needs of your project.
Do Building control accept multifoil insulation?
YES!
Multifoil insulation is being used more and more in the building of houses, especially those which are constructed using modern methods such as SIP panels. SuperFOIL insulation is perfect for these types of applications, and we will even provide you with approved U-value calculations to be submitted alongside your building control application, making the approval process easy.
Why chose multifoil over traditional insulation?
We aren’t saying that traditional insulations aren’t good at their jobs because this isn’t the case. However, there are certain advantages that multifoil insulation can offer that PIR boards or fibre insulation just can’t meet.
One main different between traditional insulation and multifoil insulation, is that traditional types of insulation only cover you against two different types of heat loss: conduction and convection. When it comes to multifoil insulation, not only does it project against these, but also offers protection against radiant energy too. What this means for the user is that all three types of heat loss are being combated, meaning your insulation is higher performing and helps keep the house warmer in the winter and cooler in the summer.
Another big advantage of SuperFOIL insulation, is the ease of which it is installed into the project. Compared to installing traditional insulation which needs cutting to fit between rafters, creating mess and requiring PPE, there is none of this with multifoil insulation. Simply install in a continuous layer over the face of the timbers and staple into place.
Why should I choose SuperFOIL over other multifoil insulation?
With a wide range of multifoils on the market, it’s easy to wonder which product you should be choosing for your project.
When selecting a multifoil insulation, it’s easy to see why some people think that one multifoil is the same as the next. However, this is not the case when you chose SuperFOIL insulation.
SuperFOIL have made it easy to choose the correct insulation for you project due to the fact we manufacture the biggest range of multifoil products available, each of different thicknesses and performance values. So, you can rest assured that whatever the project, we have something that will fit your project’s needs. From bubble foil to our non-combustible range, SuperFOIL has something for every type of application.

As you can see, with our extended range of products, the thicker the insulation the higher the R-value. This is because each product contains more layers of foil and wadding, providing a higher-performance level.
With multifoil insulations swiftly becoming the future of insulation, providing properties that other insulation types just can’t beat. However you decide to use SuperFOIL insulation, you can rest assured that whatever the project type, we will have something to meet your needs. From vapour control to breathable, we have it all.
