Case Study : Social Housing Upgrades

SuperFOIL SF40 proves to be the best solution

Social Housing UpgradesThe Problem

Hereford Housing approached SuperFOIL when they were faced with the problem of finding a high performing insulation to upgrade their existing social housing stock. It was crucial they make the best use of their investment and provide an effective solution for the future. Because the houses were occupied, all improvement works needed to be carried out from the outside to minimise the impact on the occupants. There was minimal space between rafters which left little room to add insulation. With a u-value target of 0.30 W/m2.K, traditional insulation was too thick and other multifoils were not up to the challenge achieving a u-value of only 0.67 W/m2.K.

 

 

 

The Solution

SuperFOIL worked very closely with Hereford Housing Ltd and Merriman Roofing Contractors Ltd to offer a bespoke solution. SF40 was up to the challenge. This next generation multifoil achieved 0.26 W/m2.K, significantly exceeding their target value. A single layer of SF40 and no other insulation needed with 45% higher performance over the other multifoil solutions and much faster installation times over traditional insulation solutions. The result was maximum performance, minimal thickness, improved air-tightness, radiant barrier, huge cost savings and less disruption to the residents. SuperFOIL’s superior performance excels where other products fall short.

Background

With around 5,800 homes, Herefordshire Housing Ltd is the largest social Housing Association in the county and the only Registered Provider operating solely in Herefordshire. Herefordshire Housing Association is investing £3.5 million over 5 years to increase energy efficiency in their existing properties. The work will include re-roofing, upgrade to loft insulation and further improvement works, which will have a very positive impact for the residents living in them by significantly reducing their fuel bills.
Merriman Roofing Contractors Ltd. were contracted to complete the roofing and insulation works. They have found the installation quick and easy with very little waste and are by now, the UK’s most experienced SuperFOIL installer.
