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

Loft insulation in Cranford
Insulation is the one home improvement that starts paying you back on the next heating cycle rather than in a decade. We fit it across Cranford — to full depth, with the eaves kept clear and the hatch sealed, which is where most jobs quietly go wrong.

Cranford's homes
Heat loss in Cranford: where it goes
In a typical Cranford property built during the 1880s through the 1930s, the roof accounts for the largest single share of heat loss of any element in the building envelope. Warm air rises, the ceiling is thin, and above it sits a ventilated void at close to outdoor temperature for most of the winter.
The good news is that this is the cheapest part of the fabric to improve, by a long way. Wall insulation is disruptive and expensive. Window replacement is a major capital cost. Loft insulation is a day's work with materials that cost very little relative to what they save, and it needs no permissions of any kind.
The one local caveat: the 1930s suburban expansion here produced thousands of near-identical semis, which means the same loft problems repeat street after street. We factor that in at survey stage.
Our services in Cranford
Five ways we keep Cranford 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 Cranford lofts are finished in half a day.
Loft boarding
Storage-readyTongue-and-groove panels, screwed rather than nailed so they lift again if a cable needs reaching — raised clear of the insulation throughout.
Loft ladders
Fitted in a dayMany older Cranford 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-oneOne team, one survey, one sequence of work. The insulation depth sets the batten height, the batten height sets the ladder landing — which is why doing it piecemeal costs more.

Questions & answers
Cranford loft insulation — common questions
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.
Can I still use my Cranford loft for storage afterwards?
You can, and most Cranford customers do — but the deck has to sit above the insulation, not on it. That is the whole reason raised boarding exists. Tell us at survey stage if storage matters to you, because it changes how the insulation is planned.
Can you fit a loft ladder at the same time?
We fit ladders alongside insulation and boarding routinely — it is one of the main reasons the combined makeover works out cheaper than booking the elements separately.
