SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Hextable 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 Hextable
We insulate lofts across Hextable — topping up thin or ageing material to the depth current building regulations recommend, boarding the space so it earns its keep, and fitting proper access so you can actually get to it. Every job starts with a free survey, and every price is fixed before work begins.

Why it matters
The case for insulating your Hextable 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

Put against current energy prices, a Hextable loft still carrying 100mm of settled wool is costing its owner money every single winter it stays that way.
Hextable's homes
Older Hextable homes, modern standards
Hextable's housing stock largely dates from the 1880s onwards, and the roofs above it are typically clay tile and slate pitched roofs on the older stock, concrete tile on newer development. Very little of it was built with any insulation at all; what is there now was added later, and its condition depends entirely on who added it and when.
Retrofitted insulation ages in predictable ways. Mineral wool settles and compresses under its own weight over decades. Anything that has been walked on, stored on or boarded over is thinner than it was. Material that has been repeatedly damp has lost most of its value. And the very oldest loose-fill products are often best removed entirely rather than topped over.
A specific local factor: properties closer to the estuary see more exposure to wind-driven rain, which makes checking for existing moisture in the roof space especially worthwhile. We look for that on every Hextable survey.

Five ways we keep Hextable 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 Hextable 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 dayThe thing that turns a loft you avoid into one you use. Grab rails and a boarded landing area where the design allows.
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
Hextable loft insulation — common questions
Do you offer free surveys in Hextable?
Yes. Every enquiry from Hextable and the surrounding area starts with a free, no-obligation visit. We measure the loft, check the joists and ventilation, and write a fixed price afterwards. There is no call-out charge whether you proceed or not.
Do I need planning permission in Hextable?
No. Loft insulation, boarding and loft ladders are all improvement works well outside planning control, in Hextable as everywhere else. A loft conversion — creating a habitable room with structural alterations — is different and normally needs building control approval. We do not carry out conversions.
Can you fit a loft ladder at the same time?
Yes, and it is cheaper done together. The one thing to check is the hatch: many older Hextable openings are too small for a ladder to swing through safely, so enlargement may be needed. We measure at survey and price it up front. See loft ladders.
Will this improve my EPC rating?
Usually, and often noticeably. Loft insulation depth is recorded directly by the assessor, so increasing it from 100mm to 270mm generally moves the rating. We hand over product documentation and declared performance figures so your assessor records what is actually there.
