SuperFOIL Insulation underfloor

The Project

Catherine contacted SuperFOIL due to the fact she and her family had just bought what they thought was their dream home, to later find the insulation lacking. For most people, this wouldn’t be too much of a deal-breaker, but unfortunately, Catherine’s husband had suffered a nasty work accident in 2007 leaving him with multiple medical needs, some of which are exaggerated by the cold weather.

The Problem

Upon moving into their home, they found that the bungalow suffered from severe cold bridging issues in 3 rooms, leaving the rooms feeling unbearably cold during the winter which affected Catherine and her family badly.

Catherine had started to research different types of insulation she could use under the carpet to help fix the issue, however these options were coming back too expensive for the family to afford.

Trying to do the best for her husband, Catherine reached out to SuperFOIL to see if we could help.

How We Helped

Working with Catherine and her fitter, we discussed using SFUF to fit underneath the carpets and lapped behind her skirting boards to try and minimise the cold bridging issues and to help link the existing wall insulation with the floor insulation.

SFUF was the perfect solution for the application as it’s a mere 6mm thick but provides excellent thermal values. Due to the fact it’s designed to be used on solid floors, there is no need to provide air gaps, so can be used directly under the carpet and underlay without issue.

Loft Conversion

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.
