Office conversion into residential dwellings

Project Value

Office Building Floor Insulation

The Project

A conversion of an old office block based in Wick, UK. Purchased for the price of £1.35m, with the impressive plan to convert the old offices into 30 residential units containing a mix of studio and one-bedroom apartments.

The Problem

Rizwan contacted SuperFOIL as he was looking to insulate the ground floor of the building in as little depth as possible whilst still bringing the building up to a C level of energy efficiency. Working with 1000sqm it was important that the insulation chosen provided great value for money as well as meeting the needs of the project.
As well as this, they wanted to be able to buy the insulation locally to the project and have delivery to the site.

How We Helped

After discussion with our technical experts, it was decided that SFUF would be the best option for Rizwan. At only 6mm thick and suitable to be used directly on a solid floor, this was the most practical solution as it achieved the energy efficiency level needed whilst keeping a slim profile.

Due to having distributors across the country, Rizwan’s building contractor was able to purchase the SFUF locally to the project from Travis Perkins.

When asked why he chose to use SuperFOIL for this project, Rizwan stated SFUF was used “to achieve our u-value and bring the structure to a C level of energy efficiency. SuperFOIL was extremely easy to install and easy to cut and join using basic SuperFOIL tape”.

Our technical specialist Dean stated “We have worked closely with Rizwan and his building contractor since the beginning of his conversion project. It was vital to get the correct product first time to achieve everything Rizwan needed to achieve, and this was done by using two layers of SFUF”.

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.
