Project Value

The Woodshed with SF19+ SuperFOIL Insulation

The Project

An empty space that had been left below an adventurous, architectural sundeck that had been built a number of years before. Kyle was looking to transform the space into something useful for him and his family.

A new build project, with the need of insulation for the ceiling and walls.

The Problem

Built below an existing deck, it was an empty space looking for a purpose.

The new build already had a roof formed from a fibreglass system due to the sundeck above, so it was important that the workspace had the correct insulation to ensure that there was no risk of condensation

With a lack of space, Kyle was looking for something that would be space-saving, whilst remaining affordable and easy to install for one person.

How We Helped

After requesting a U-value and condensation risk analysis from our technical team, Kyle worked with the team to come up with the perfect solution.

After discussion, it was decided that Kyle would use a layer of STFV alongside SF19+ on the roof. This was to ensure that there was no risk of condensation due to the existing flat roof construction and lack of ventilation this construction offered.

SF19+ was used on the walls of the project, which provides an R-value of 2.97 when installed in a wall application, it also provided a radiant barrier and vapour control layer to the installation.

Kyle installed the insulation himself, reporting that the products were “easy to cut and use, which was great”, as well as being ” clean, dust-free, non-smelling or scratchy ” like other traditional insulation types which was a “massive benefit”.

When asked why he chose to use SuperFOIL, Kyle said that it’s “Relatively affordable, new technology. Space-saving on height and wall voids. Easy to install on my own and my daughters love the silver room, spaceship interior!!”

Actually, I bought Superfoil for my small extension and I must say easy to install and it works, room is comfortable better than Kingspan. Now looking at installing an underfloor in my daughter's house. Thanks!

I'm really grateful for all the info you've provided, many thanks. To be honest I didn't think your stuff is as good as it clearly is, and we'll definitely be using it in the future. Can I ask a favour and ask you to calculate two more please?

In the past, I used SF19 for thermal insulation of the roof. I have the best experience. I'm thinking about insulating the house outside wall. As I want to be clear, I will definitely call. Many satisfied customers wish.

We’re delighted with the thermal improvements after fitting Superfoil SF40. The system was clearly and helpfully specified, simple to install and immediately felt warmer, despite this also being the Winter of Beast from the East. It suits our 200 year old house, now heated with a modern, green air source heat pump.

Many thanks for all your assistance with this matter, you have been very helpful. The information you have provided has been very useful to one of our customers and I am now more familiar with this type of double fit of SuperFOIL as a suitable method of achieving compliance with The Building Regulations.
