About this service
SuperFOIL is a thin multifoil insulation fixed to the underside of the roof. It suits attic rooms, low-pitched roofs and lofts used for storage, where 270mm of wool on the floor is not practical.
What’s included
- Free assessment of roof and ventilation
- SuperFOIL multifoil fixed to the rafters
- Joins overlapped and taped
- Edges and penetrations sealed
- Ventilation paths kept open
- Boarding or ladder available alongside

Mineral wool laid across the loft floor is the right answer for most lofts. But it is not always practical. If you use the loft as a room or a hobby space, if the roof is too low to fit 270mm on the floor and still reach the eaves, or if you want the roof space itself to be less cold, insulating the roof instead can make more sense. That is where SuperFOIL multifoil insulation comes in.
We fit SuperFOIL in lofts, attic rooms and low-pitched roofs across Middlesbrough, Teesside and the wider North East. Every job starts with a free assessment, because how well multifoil works depends on the roof it goes into and how carefully it is fitted.
What multifoil insulation is
Multifoil is a thin, flexible insulation made from layers of reflective foil separated by layers of wadding. It works differently from mineral wool. Wool slows heat down by trapping still air in a thick blanket. Multifoil combines its own insulating layers with reflective surfaces that face sealed air gaps on either side. Those air gaps are part of how it works, so they have to be formed and kept intact.
Because multifoil is fitted as a continuous sheet with taped joints, the joins and edges matter. A carefully taped installation behaves very differently from a loosely fixed one. We do not quote performance figures on this page, because the real result depends on the roof build-up and the air gaps. We explain the options for your roof after the assessment.
Who SuperFOIL suits
- Lofts used for storage or as a space. Insulating the roof makes the loft less cold and leaves the floor free to board.
- Attic rooms with sloping ceilings, where there is little space for thick insulation.
- Low-pitched roofs, where 270mm of wool on the floor would leave no room to work at the eaves.
- Homes where the floor is already boarded and lifting it is not practical.
For a plain, unused cold loft, mineral wool loft insulation on the floor is usually the simpler and better value choice. We will tell you honestly which suits your loft.
How SuperFOIL is fitted
Checking the roof first
Before anything is fitted, we look at the roof covering, the felt or membrane under the tiles, the rafters and how the loft is ventilated. Older bitumen felt does not let moisture through, while modern breathable membranes do, and that affects how the roof must be detailed. Any existing damp or mould needs dealing with first; see mould and condensation.
Fixing to the rafters
The multifoil is fixed to the underside of the rafters, between or across them depending on the roof, with battens or fixings to hold it in place and form the air gaps it needs. Joins are overlapped and taped, and edges are sealed around the perimeter, so it forms a continuous layer.
Around the details
Penetrations such as soil vent pipes, chimneys and cables are taped around carefully. Ventilation paths that the roof relies on are kept open, so moisture can still get out. See loft ventilation for why that matters.
Combining SuperFOIL with other work
SuperFOIL often goes in alongside other loft jobs:
- Raised loft boarding to give a storage floor in a loft that is now less cold.
- A loft ladder for easy access.
- A top-up of the floor insulation, where both are wanted.
Building regulations
Where multifoil is used as part of a loft conversion or other work that needs building regulations approval, the overall roof build-up has to meet the required standard, and multifoil may need to be combined with other insulation. That is a matter for your designer and building control. Our work is focused on improving existing lofts and roof spaces, and we will tell you if your project needs more than we provide.
What affects the cost
The price depends on the roof area to be covered, the roof shape, access, how many penetrations need detailing and whether other work such as boarding is included. You get a written quotation after a free assessment. See the loft insulation cost guide for more on what affects the price.
Who does the work
SuperFOIL is fitted by The Insulation Company or an approved installation partner. Eligible installations come with a written guarantee of up to five years; the terms are set out in your quotation.

Fitting
Multifoil is fixed to the rafters, joins are taped, and edges and penetrations are sealed.

Completion checks
Ventilation paths are checked, the area is tidied and you are shown the finished roof.
SuperFOIL Insulation: your questions answered
Is SuperFOIL better than mineral wool?
Not for every loft. For a plain, unused loft, mineral wool on the floor is usually simpler and better value. SuperFOIL suits lofts used as a space, attic rooms and low roofs.
Can SuperFOIL go over my existing loft insulation?
It is fitted to the rafters, not the floor, so it does not replace floor insulation. In some lofts both are used. We explain the options at the assessment.
Does multifoil need an air gap?
Yes. Its reflective surfaces work with sealed air gaps either side, so it has to be fixed in a way that forms and keeps those gaps.
Will SuperFOIL cause condensation?
It should not if the roof is assessed first and ventilation paths are kept open. The type of felt or membrane under the tiles affects how it is detailed.
Can I board my loft after fitting SuperFOIL?
Yes. Raised loft boarding can be fitted alongside it.
How much does SuperFOIL cost to fit?
It depends on the roof area, shape, access and detailing. You get a written quotation after the free assessment.
