Outbuilding roof with SuperFOIL insulation

The Project

The dad of a young man with cystic fibrosis, Chris –  contacted us as he wanted to insulate a 3x3m wooden cabin in their back garden. The cabin is used to house exercise equipment that Chris uses to ease anxiety and the symptoms of a bone condition.


After a double lung transplant and issues surrounding organ rejection and infections, Chris requires constant medication and monitoring for other on-going issues including diabetes, osteoporosis and complications with his digestive system.


Because he has a life expectancy of just a few more years, his family is helping him to find ways to take his mind off this and support his mental health – and one of these is an interest in exercise.


Unfortunately, the cabin was uninsulated, becoming overly cold in winter and unbearably hot in summer, making it unusable for a large portion of the year.

The Problem

How We Helped

Chris’ dad, Dan had been looking into the best products to make the cabin a more comfortable temperature and saw that SuperFOIL SF60 was exactly what he needed; being easy to install, narrow and flexible.


He wrote to us about the situation and we were happy to help, supplying all the kit he’d need to insulate the cabin.


Fitting the insulation was a breeze: 


“I had to cut the insulation along its length to give me approx. 73cm for the distance between the beams and taped up the rough long edge – the width of the superFOIL was just right for this with no waste – made for the job!! Installation was easy using a staple gun and two people.”

    • Dan


Using a laser thermometer on the inside of the roof before installation showed the inside temperature reached 28 degrees celsius in full sun. Once the SuperFOIL insulation was installed, the internal temperature reduced to 19 degrees.


With our SF60 installed, the cabin is a much more comfortable environment for Chris to exercise in, helping his health and happiness.

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.
