We insulate the roof space – thermal insulation between and under the rafters or across the loft floor, with a vapour barrier that keeps moisture from the home out of the insulation.

If the loft is not used, it usually makes more sense to insulate its floor rather than the roof slopes – the area is smaller and the insulation is easier to lay. In an attic room, the insulation follows the slope of the roof and is closed in with a vapour barrier and lining.
Before we start, we check that the roof is dry and that there is a vapour-permeable membrane and ventilation above the insulation. Insulation under a roof that leaks or cannot breathe gets wet and loses its effect.
Technical detail: the vapour barrier
If the vapour barrier has gaps, moisture from the warm air in the home condenses in the cold part of the insulation. That is why the membrane goes on the inside, the laps are taped and the cable penetrations are sealed.
The most common situations people call us about, and how we approach them.
Process
We organise the work around the specifics of the city and the property, planning access, logistics and stages.
The price depends above all on whether you are insulating the roof slopes of an attic room or the floor of an unused loft, and on the thickness required.
The exact price is set after an inspection of the roof space.

Every completed project receives a warranty certificate. This is what it covers and for how long.
The extended term applies to the installations themselves and to the roofing work. Installed ready-made products — taps, fittings, appliances — carry the manufacturer's warranty.

“Punctual and honest – I recommend them.”
If the loft is not used, it is usually more effective and cheaper to insulate its floor. If it will be lived in, the insulation goes along the roof slopes.
To stop moisture from the home reaching the cold part of the insulation, where it condenses. Wet insulation loses its properties and leads to mould and rotting timber.
Yes, if the roof membrane is sound and the roof does not leak. If there is no membrane, the solution is decided at the site visit – sometimes work from outside is needed too.
No – it is hard to fit tightly and leaves gaps that let the cold through. Mineral wool is normally used there, as it fills the space and lets vapour pass through.
It depends on whether you are insulating the floor or the roof slopes, and on the energy-efficiency requirements. On the slopes, the thickness needed is usually greater than the depth of the rafters, so a second layer is laid beneath them.
We will check the roof space and tell you whether to insulate the loft floor or the roof slopes.
