SuperFOIL Throws down the gauntlet!
SuperFOIL are so confident that SF60 is the highest performing multi-foil insulation in Europe that we are throwing down the gauntlet with the SuperFOIL Challenge. Quite simply this is our guarantee that if you find a multi-foil insulation that has a higher thermal performance than SF60 we will give you your money back.
SuperFOIL SF60 is an innovative product from a British company, designed by us with testing completed by the UK’s premier body the BBA to the standards set out by Building Regulations. Our mission is to to give our customers better thermal performance than any other multi-foil insulation in Europe. SuperFOIL SF60 is at the leading edge of multi-foil insulation performance.
Superfoil SFNC Non Combustible Multifoil Insulation
Using Superfoil in buildings to meet Part B of the Building Regulations, ‘Fire Safety’ .
Superfoil can be used in walls and roofs as part of a construction designed to meet the requirements of Building Regulations for fire safety (as well as Part L, Conservation of Heat and Power of course) .
Superfoil provides the insulation element of the construction; the total construction takes in to account the structural elements and other items such as external/internal finishes. The design, in terms of meeting Part B, must ensure the integrity of load bearing structure,indicate the means of warning / escape and consider the spread of fire both internally and externally. It also, in respect of external walls, must also take in to account the proximity to other properties and the effect this has on the requirements for surface coverings
At the leading edge of the fire classification scale are ‘A’ classified multifoils; these are truly Non Combustible materials,. There are stringent testing methods to comply with this rating including what’s referred to as the ‘bomb test’ in the industry.
Regular multifoils are sometimes described as flame or fire retardant; all reputable manufacturers fire test their products. The assessment for fire rating is complex as you might expect. The European Fire Classification range is from A to F; multifoils generally are classified as ‘F’ under this system and only achieve E classification when used as directed in walls and roofs behind plasterboard and or other approved internal finish materials. Please note multifoils are not a suitable finish surface for a habitable room in residential construction e.g. bedroom, living room.
Superfoil SF19, SF40 and SF60 achieve an ‘E’ classification when contained in a construction. It may be obvious but for completeness, Superfoil SFNC is ‘A rated.
Standard multifoil products are made from plastics and aluminium and they will melt and/or burn in a fire ( as will foam insulation board, electrical cable coverings, wood timbers, polythene liners etc ), Superfoil SFNC is an ‘A’ classification (non combustible) multi foil insulation, Superfoil SFNC stands for SuperFoil Non Combustable.
Regular multifoils can be and are widely used as part of a typical residential construction. Non combustible multifoils are usually for specialist use in environments such as military and marine situations and to protect buildings in areas with a risk of bush or forest fires e.g. as in Australia and California. Sometimes a fire separation between compartments like lofts open over more than 1 property is required.
The cost difference between regular and Non Combustible multifoils is substantial and unless there is a particular requirement not much is gained by their use in typical residential construction , SFNC is also considerably heavier than regular multifoils.
Regular multifoils, such as Superfoil SF19 (and other insulations) when installed with an internal lining board, e.g. 12.5 mm thick plasterboard,will be contained between the external part of the structure and internal lining board and as such they do not contribute to the development stages of a fire or present a smoke or toxic hazard. They must not be carried over junctions in buildings required to provide a minimum period of fire resistance and the continuity of fire resistance must be maintained. Generally combustible materials are permitted in a cavity but any opening has to be sealed.
We are often asked if Superfoil SF19, SF 40 and SF65 can be used with heat-producing,solid fuel or oil or gas-fired heating installations? Superfoil can be designed and constructed to comply with the required standard provided that the multifoil is isolated from the flue of a gas-fired,solid fuel or oil-fired heat-producing appliance by a separation appropriate to the heat of the appliance. Superfoil SFNC being non combustible does not have the same constraint as the standard product.
Whilst focusing on fire regulations we should not forget the thermal performance of Superfoil. Superfoil when used in a building will provide not only high levels of insulation, it will also provide a radiant barrier, it will assist in the ease of achieving improved air tightness. Depending on the construction a wall with just one layer of SF40 will achieve a U value of U 0.26 or better with no other insulation at all, exceeding the insulation requirements of Building Regulations by over 10%. One layer of SF60 will achieve a U value of U 0.19 or better i.e. exceeding current Building Regulations for walls by more than 50%.

Superfoil uses the latest NANO technology in the coatings of its reflective foil surfaces. Our SF19, SF40 & SF60 multifoil insulation products make use of ultra efficient DuPont Nano Coating technology. This reduces the thickness of the coating used to provide corrosion resistance, and protection of the foil faces, down to a very thin micro thickness layer of extremely tough nano particles. This enhances reflective foil properties significantly, with 97% efficiency. Nano technology is a leading edge 21st century advancement and provides significant improvements over foils still using traditional 19th century NC (nitro cellulose) protection.

The set designers on the latest Tom Cruise block buster movie ”In the name of Kill” are undecided which of the Superfoil range to use on set – do we choose SF19, 40 or 60? The set requires space age products and they bought SF19 (from merchants Travis Perkins) they now want more and are considering using the thicker SF40 or SF60 on the film set of ”In the name of Kill”, a time travelling alien sci-fi adventure.
From small beginnings for multilayer foil reflective insulation at NASA and the moon shot and space race, multilayer foil insulation with Superfoil is now helping to save the planet from alien invasion…to be continued
BBA, the British Board of Agrement, have tested Superfoil SF60 to EN12667 and issued test report certificates. (see the down load section of this web site). Testing to standard EN12667 includes the test standards EN8301 and EN6946 and meets Building Regulation part L requirement of BR443, for regulation requirement for the testing of thermal performance of reflective insulation. Superfoil Insulation Systems use reflective technology to maximum thermal performance of a roof construction.
R values in Roofs with 1 layer of SF60 are R4.42 and one layer in walls is R4.88. when installed to our standard installation system method. For sloping roofs achieving U values of U 0.18 is easy with a 20mm HD foam board between or below rafters. For walls a U value of U 0.19 is achieved with 1 layer of SF60, this is far in excess of the usual building regulation requirement for walls of U 0.28. U values as low as U 0.1 can be achieved in other system combinations.
In addition Air tightness and Radiant Barriers are incorporated in the Superfoil Insulation System to reduce solar gain and air movement losses.

Just-Insulation (http://www.just-insulation.com/multifoil.html) had this to say about the Superfoil range:
“SuperFOIL– for and against:
SuperFOIL manufactures the largest variety of multi-foil products.
SuperFOIL SF19 (40mm) costs less per square metre than any of the other multi-foils that we sell.
SuperFOIL SF40 (65mm) represents the best value multi-foil when comparing cost against thermal performance, ie R Value 3.54.
SuperFOIL SF60 (100mm) is the most robust multi-foil product currently. available, and with an R Value of 4.643, it is, by far, the most effective multi-foil product available today.
SuperFOIL SFUF (6mm) multi-foil for under-floor insulation and heating systems costs almost half the price of its only competitor Actis Triso Sols
SuperFOIL products has LABC Registered System Approval No. RD199-0512. And SF19 and SF40 have BBA Test Certificates.”
As part of a program of school energy efficiency upgrades SF40 is being installed to schools in the Nottingham and Lancashire areas during the summer holidays, making buildings ready for the cold winter months. A bonus for schools is that SF40′s reflective radiant barrier keeps buildings cooler in summer too, combating solar gain (solar radiation) and reducing the need for air conditioning and making further energy savings.
The performance of SF40 exceeds all other standard multi layer foil insulation. As a premier product its been chosen for this prestigious schools program.
Double thickness SF40 is unique to Superfoil and is part of the Superfoil range that includes SF19, SF40, SF60 for roofs & walls, SFUF for floors and SFTV membrane.
Dormer Cottage Solutions
In dormer cottages, (new roof or renovations) there is a section of the roof that takes a little thought to insulate well because the inside (room) and the outside (roof) are in very close proximity where the pitch of the roof cuts through the room, some times there is as little as 100mm between the warmth of the room room and the cold outside air. In a Swiss chalet type building this area can be quite large, in a dormer cottage its usually smaller .
A solution is to insulate both between and under the rafters. Superfoil SF19, SF40 or SF60 can all be used under the rafter in a COMBI arrangement with HD foam board between the rafters. Which Superfoil and how much foam board depends on the U value to be achieved (current building regs require at least U 0.18 , in Scotland its 0.15 for a roof insulated on the slope of the rafters ).
If the rafters are small as is often the case with manufactured trusses the depth of the rafters may be very limited and in those cases the higher performance Superfoils are used under the rafter . If the space between rafters is deeper as in a cut timber roof then more foam board insulation between rafters and the standard Superfoil SF19 under the rafter should give the desired performance. The pictures shown here are from a customers project, they have used SF40 under the rafters combined with 60mm of Kingspan K5 PIR foam board between rafters, ( a 25mm air gap between them). a 38mm batten is in place for the fixing of the plasterboard. The result in this project is a better than building regulations 0.16 U value.
With SF60, which the highest performance multifoil avalabe in Europe under the rafters you can achieve U 0.18 even on rafters as small as 85mm deep by using 20mm of foam board eg PIR board. Combinations of Superfoil and foam board to meet U0.18 include SF60 with 20mm of foam board, SF40 with 45m of foam board, SF19 with 80mm of foam board. Assuming Kingspan K5 or similar and 25mm air gap. Specifications can vary from project to project, ask us for a U value calc for your particular construction.
Other solutions using Superfoil in DUET format (2 layers ) in under or over rafters combinations are also possible to achieve U values as low as 0.11.
Winter is still some way off, but ahead of the coming Winter Superfoil has released a new and very competitively priced Cold Weather tape, SFCW, its available in 50m rolls and is 80mm wide with an RRP of £10.65 per roll. This joins the standard SFMP tape which is 20m long x 100mm wide with an RRP of £6.95 and the pure Aluminium tape SFPA 45m x 100mm with an RRP of £9.95. Individual rolls and Boxes of 18 rolls are available.

Air is a very good insulator, for instance the thermal conductivity of air is 0.24, which is much better than old fashioned glass fibre at 0.44 (the lower figure the better). Above and beyond that a sealed air gap next to a reflective surface improves the R value of the air, there is a useful EN standard called EN6946 that you can use to calculate the R value of an air gap if you have the emissivity (reflectiveness) of the foil.
A sealed air gap will be up to 200% improved if the emissivity of the foil is good. Air is a good insulator but its important that the air is kept still; convection currents in air reduce performance. This is why glass wool was used an an insulator for a long time, it works to keep air from moving around. If you compare the thermal conductivity of glass to glass fibre it is very poor (think how cold single glazing is); the same glass made into glass wool is a lot better because although its an open structure it’s trying to keep the air still. Foam board is the same, doing what glass wool does but more efficiently.
Multi layer foil insulation takes the technology further, combining sealed air gaps with reflective surfaces to not only create efficient air gaps but to create super efficient low emissivity air gaps. Each layer in Superfoil multi foil insulation creates an improved performance air gap and beyond that creates improvements between its self and the plaster board below and the secondary rain barrier membrane above.
In a roof EN6946 states that the efficiency starts to reduce in air gaps below 13mm, in walls its 20mm. Battens are incorporated in the construction detail of Superfoil multifoil to ensure the minimum air gap is maintained. A multilayer foil can reduce a timber frame wall from 300mm, sized to accommodate the amount of glass wool needed, to that needed purely for structural strength, which may be only 100mm. A significant saving on timber and labour is achieved.
Air is a good insulator and Superfoil multifoil insulation takes the greatest advantage of that. Air is also probably the cheapest form of insulation available! Superfoil multilayer foil insulations maximize the contribution of air, by applying science and technology to create a leading edge insulation.
