SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Hounslow loft has already been converted, insulation has to follow the rafters rather than the floor. SuperQuilt does that in 40mm instead of the 200mm-plus a wool build-up would need.

Loft insulation in Hounslow
If your Hounslow loft has 100mm of flattened wool and a boarded patch balanced on the joists, you are not alone and you are losing money every winter. We fit insulation to the recommended 270mm depth, and raise any boarding clear so it keeps working.

Why it matters
The case for insulating your Hounslow loft
25%of a home's heat is lost through an uninsulated roof
1 in 5UK lofts are under-insulated or have the wrong material
270mmthe depth current building regulations recommend
90%less radiant heat loss with SuperQuilt multifoil
Those figures are national, but the logic is entirely local: the roof over a Hounslow house is the cheapest part of it to improve, and the part losing the most.
Hounslow's homes
Hounslow: what a survey usually turns up
Housing across Hounslow and the surrounding West London area is largely Victorian terraces, large Edwardian villas, extensive interwar suburban development and post-war blocks, built through the 1880s through the 1930s. When we open a hatch here, the most common finding is not an absence of insulation but an insufficiency of it — a layer that was correct when fitted and has since been overtaken by both the guidance and the price of energy.
The second most common finding is a ventilation problem. Insulating a loft floor makes the roof space colder, and a colder roof space condenses more readily. Where a previous installer packed material tight into the eaves, the roof has lost the airflow it depends on and the homeowner has a damp loft they blame on the insulation rather than on the installation.
Add to that the local factor — the 1930s suburban expansion here produced thousands of near-identical semis, which means the same loft problems repeat street after street — and you have most of what a Hounslow survey is checking for.

Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.

Questions & answers
Hounslow loft insulation — common questions
How much does loft insulation cost in Hounslow?
There is no single figure, and anyone offering one for Hounslow without seeing the loft is guessing. The largest swing factor is almost always whether the existing material can be topped over or has to be stripped out and disposed of. We survey free of charge and quote a fixed price afterwards.
Will insulating my loft cause damp?
Not if it is done properly. Insulating the floor makes the roof space colder, so moisture condenses more readily — the defence is the ventilation path at the eaves. Blocking it with insulation is what creates damp lofts. We keep it clear on every job. Our ventilation guide explains the mechanism.
