SuperFOIL SFTV 1L

Protect your living spaces from condensation and minimise up to 95% of radiant heat loss or gain; you only need one product for both.

Reflective Radiant Barriers For Use In Roofs, Walls & Floors…

The highly reflective foil surface acts as a barrier to reflect radiant heat rather than absorb it, like traditional insulation types. Radiant Barriers minimise solar heat gain and overheating during summer and help retain heat inside your property during winter. This means Radiant Barriers are the perfect solution to reduce your dependence on heating and cooling systems, saving you money on energy bills and preventing structural damage from condensation.

How SuperFOIL SFTV 1L Benefits You

SFTV 1L is a true 2-in-1 designed product, providing a reflective radiant barrier in addition to a vapour control layer, outshining traditional insulation solutions when used in place of a standard vapour membrane. The product has been rigorously tested and certified to achieve almost three times the performance of a standard vapour control layer. This means that the high vapour resistance prevents warm air or water vapour from penetrating through the wall, significantly reducing the risk of condensation, mould, and subsequent structural damage to your property.

The highly reflective surface of SFTV 1L allows it to act as a radiant barrier. By reflecting radiant heat, SFTV 1L minimises solar gain and overheating in summer, keeping your home cool in the summer and retaining heat inside the property during winter for warmth. With the prevention of condensation and mould, a clean, thermally efficient  and comfortable indoor environment is also guaranteed year-round.

Applications

Due to their highly reflective properties, SuperFOIL SFTV 1L can be applied across roofs, walls, and floors in new build, retrofit, and extension projects, whether domestic or commercial. The thin, easy-to-install and clever design facilitates the application and ensures tailored solutions for every project, either in single or duet setups, with minimal wastage and no unnecessary cleaning up after installation. This also eliminates your need to integrate any additional vapour control products to protect your property.

Amazon review for SuperFOIL products

Easy to use, cut to size without any waste once measured carefully. Something I've thought of doing for many years but, never got round to it. Intend to sit back and hope it preformed as promised, I'm sure it will since the product is hailed by the experts on energy performance and importantly enough for seven radiators. Definitely recommend. Thank you..

Google review for SuperFOIL Insulation

Superfoil products radically simplified achieving the required insulation ratings for our renovation / extension project. I was very keen to maximise internal space in both the dormer spaces and a very large flat roof avoiding tall external build up. The technical team provided detailed options and then were more than happy to iterate these to refine the final solution. I ended up using a hybrid solution of SF40BB and SF40 along with Vapour barrier and mineral wool. I would recommend speaking to the tech team – they certainly allowed me to get the outcome I wanted.

Amazon review for SuperFOIL products

Very pleased with this kit and within about 2hrs it was installed. The insulation most closely resembles bubble wrap however was much thinner and behaved more like cardboard. Very easy to cut with a pair of scissors and the supplied double sided tape is good quality. The 100mm wide tape is a bit fiddly as it is wider than scissors and tears easily however with a bit of patience it worked well. Installation – The insulation comes in 600mm wide rolls which is a bit smaller than I needed to do a full horizontal section, I decided to cut twelve small individual panels, plus two full width strips to finish with. I stuck the double sided tape all around the outside edge on each of my three horizontal areas, I also sprayed contact adhesive onto the metal door inside the tape frame. I then used four of the small panels on each area with around 10cm overlap. I finished by running double sided tape along the horizontal bars that were remaining and covering with the long strips of insulation. Finally, I taped between all of the sections to create one large airtight piece. The contact adhesive probably isn’t needed however at £6 for a spray can on Amazon I thought I may as well secure it properly. Final results are a noticeable reduction in outside noise and a lot more light in the garage for working on my bikes, hopefully it makes the garage easier to heat in winter and not allow the temperature to get too high in summer. We’ll see! Garage door opens and stays open with no obvious strain on the mechanism from the additional weight. Overall very pleased with the kit and a bargain imo.
