SuperQuilt multifoil insulation
A/A+ fire ratedMultifoil earns its place in Charlton roofs where depth is the binding constraint — period timbers, low headroom, or a conversion already boarded out.

Why it matters
The case for insulating your Charlton 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
The reason we lead with the roof rather than the walls or the windows is arithmetic: in a typical Charlton property it is the largest single heat loss and the smallest single bill to fix it.
Charlton's homes
Charlton: what a survey usually turns up
Housing across Charlton and the surrounding South East London area is largely Victorian and Edwardian terraces on the older high ground, extensive interwar semi-detached suburbs, and post-war estates, 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 — hipped roofs on 1930s semis cut the usable loft area down sharply at the corners, which changes how much of it is worth boarding — and you have most of what a Charlton survey is checking for.

Five ways we keep Charlton homes warm
Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.
Loft insulation installation
270mm depthThe standard job, done to standard: two layers, the second laid across the joists to kill the cold bridge, eaves left clear. Most Charlton lofts are finished in half a day.
Loft boarding
Storage-readyA squared, edged deck reached from the hatch, with the eaves left open so the roof keeps breathing. Sized to what you will actually use rather than the whole Charlton footprint.
Loft ladders
Fitted in a dayMany older Charlton hatches are too small for a ladder to swing through safely. We measure at survey and price any enlargement up front rather than on the day.
Loft makeovers
All-in-oneFor Charlton homeowners who want the roof space to stop being a problem and start being storage: everything, in a day.

Questions & answers
Charlton loft insulation — common questions
How long does the work take in a typical Charlton home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Charlton lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
What happens to the water tank and pipes?
Pipes get lagged and the tank gets insulated on the sides and top only. Leaving the base open is deliberate — it is the only thing preventing a frozen tank in a hard winter.
Do you remove the old insulation?
It depends what is up there. Cross-laying a new layer over sound existing material is both cheaper and perfectly correct. Failed, contaminated or loose-fill material is stripped, bagged and disposed of — slow work, and we show it as its own line on the quote.
What insulation depth do you fit?
270mm of mineral wool, cross-laid — the depth current building regulations guidance points to for a cold loft. Where a Charlton property has a room in the roof and depth is constrained, we use 40mm multifoil at rafter level instead.
