SuperFOIL insulation in Sheffield: 31m² of SuperFOIL SF19+ Fitted to the Rafters
In October 2026, EcoTrust Roofing & Insulation Ltd stripped the old plastic sheeting from the rafters of a loft in Darnall, Sheffield, South Yorkshire. The team then fitted 31m² of SuperFOIL SF19+ multifoil insulation to the rafters, stapled and taped to spec, backed by a 10-year guarantee.
The problem
The homeowner wanted the roof slope itself insulated. Our surveyor measured 31m² of rafters to line with SuperFOIL.
The underside of the roof was covered in old plastic sheeting. That had to come off first so the new multifoil could be fixed tight to the rafters and every joint taped.
What we did
- Free survey: measured 31m² of rafters and agreed a fixed written price for the work.
- Stripped the old plastic sheeting from the underside of the roof.
- Stapled SuperFOIL SF19+ multifoil to the rafters, working around the brick chimney breasts and gable.
- Taped every joint with SuperFOIL tape so the foil forms one continuous layer.
- Came back for a short return visit to finish off and sign the job off.
The result
The 31m² roof slope is now lined with SuperFOIL SF19+, stapled to the rafters and taped at every joint, with the old plastic sheeting gone.
The work is covered by EcoTrust's 10-year guarantee, and the homeowner has a completion certificate listing exactly what was fitted.
What the customer said
“…they came straight back out and sorted everything without any fuss.”
“Really happy with the service from Eco Trust. They came round promptly, gave me a quote and managed to fit me in the following week.
Two of the lads turned up and got straight on with the job. They were clean and tidy throughout, took all the rubbish away and left the loft space nice and tidy once they'd finished.
There were a couple of minor issues with some of the tape not fitting quite right, but after a quick phone call, they came straight back out and sorted everything without any fuss.
Really pleased with the end result. The loft is now much better insulated, and the whole process was straightforward from start to finish.
Great customer service, professional lads and an all-round good job. Would happily recommend Eco Trust!”Paul, Sheffield 5/5Google review · Oct 2026
SuperFOIL insulation in Sheffield: questions we get asked
What is SuperFOIL SF19+ and where does it go?
SuperFOIL SF19+ is a multifoil insulation made of layered foils and wadding. In this Sheffield loft we fixed it to the underside of the rafters, so the roof slope itself is insulated. It suits lofts used for storage or rooms where you want warmth up in the roof, not just on the floor.
Do you remove old sheeting or insulation first?
Yes, when it is in the way. Here in Sheffield the rafters were covered in old plastic sheeting, which we stripped off first. That lets the SuperFOIL sit tight against the timber and lets us tape every joint, so there are no loose flaps or gaps for heat to escape through.
Why do the joints need taping?
Multifoil works best as one continuous layer. Every overlap on this Sheffield job was sealed with SuperFOIL tape, so warm air cannot slip through the seams. Untaped joints leave gaps, and gaps let heat out and can let moist air reach the cold roof timbers.
Is SuperFOIL insulation guaranteed?
Yes. EcoTrust SuperFOIL installs come with a 10-year guarantee, including this 31m² job in Darnall, Sheffield. You also get a completion certificate that lists exactly what was fitted, so you have a clear record of the work for your own files or if you ever sell the house.
