SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Bounds Green 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.

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 Bounds Green — to full depth, with the eaves kept clear and the hatch sealed, which is where most jobs quietly go wrong.

Why it matters
The reason we lead with the roof rather than the walls or the windows is arithmetic: in a typical Bounds Green property it is the largest single heat loss and the smallest single bill to fix it.
Bounds Green's homes
Bounds Green's housing stock largely dates from the 1870s through the 1930s, and the roofs above it are typically steeply pitched slate and clay tile roofs with usable, walkable voids above the top floor. 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: many of the larger houses were divided into flats decades ago, so the loft often sits above a top-floor conversion with its own separate access. We look for that on every Bounds Green survey.
Our services in Bounds Green
Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.

Where a Bounds Green 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.

The standard job, done to standard: two layers, the second laid across the joists to kill the cold bridge, eaves left clear. Most Bounds Green lofts are finished in half a day.

Storage that does not flatten your insulation. We raise the deck on battens so the full depth survives underneath — the version most Bounds Green lofts should have had first time.

Fitted in a day, finished to match your landing, with the hatch insulated and draught-sealed as part of the same job.

Insulation, boarding, lighting and a ladder handled together in one visit — cheaper and better sequenced than buying the four separately.
Describe the property and what is bothering you about it, and we will recommend the right combination — or tell you that nothing needs doing.
Where we work
Enfield and Northumberland Park are all covered by the team that works Bounds Green, which is why we can usually offer a survey slot within the same week rather than the same month.

Questions & answers
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.
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.
No. Loft insulation, boarding and loft ladders are all improvement works well outside planning control, in Bounds Green 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.
