A multifoil installation completed for a Victorian mid-terrace with a converted top floor in Hanover by one of the vetted installers we work with. We started with no insulation at all between the rafters, just felt and plasterboard — here is what changed, in the installer's own photographs.



These photographs are from a real loft project carried out by one of the vetted installers we work with. Brighton Loft Insulation arranges the free survey and the written quote; the installation itself is carried out and guaranteed by the installer. Property details are described in general terms — we do not publish customer names or addresses.
The property is a Victorian mid-terrace with a converted top floor, a type you see a great deal of around Hanover and the streets near it. The starting point was no insulation at all between the rafters, just felt and plasterboard — well short of what a roof needs to hold heat in through the winter and keep it out through the summer.
Before anything was specified, the loft was checked properly: the access, the joist layout, the condition of whatever was already up there, the airflow at the eaves and any sign of moisture. That inspection is what decides the work. A photograph and a phone call are not enough to specify a loft, and we would not quote a job on that basis.
The recommendation was SuperFOIL SF19 fitted at rafter level, taped at every joint across roughly 22m² of roof slope, with a continuous air gap maintained above and below the foil. The work took one day, and the loft was cleared and left tidy at the end of it.
Multifoil earns its place where headroom is tight — a converted loft, a room in the roof, a shallow pitch. It is a layered reflective product fitted at rafter level with an air gap either side, so the ventilation path has to be planned before anything goes up. SF19 is a product, not a depth.
The top-floor room is no longer the coldest in winter and the hottest in July. A typical price range for work of this size and type in Brighton is £1,080–£1,320. The only figure that really means anything, though, is the one on your own written quote — after someone has been up and looked.
If your home is anything like this one — thin or settled insulation, a converted room that never quite feels right, storage sitting straight on top of the layer, or simply no idea what is up there — the first step is the same for everyone.
