Product Description

SF40 is Superfoil‘s extra performance multifoil insulation. Extremely cost effective with a 68% increase in performance over our standard multifoil. SF40 beats any multifoil competitor products R value.

With a mission to build a better multi foil insulation SF40 combines the technical innovation of 37 layers and is configured for maximum efficiency, achieving higher values than previously thought possible within the industry. The enhanced thickness combined with radiant reflective properties and air barrier properties provide benefits over traditional (non reflective) open face insulation like glass fibre. SF40 includes CE certified vapor and water barrier outer layers.

SuperFOIL SF40 maximises roof and wall insulation with efficient use of space. SuperFOIL also has the strongest multi foil material aiding installation and reducing waste. LABC registered detail makes Building Regulations simple.

Questions & Answers

Question:

Can superfoil be used to insulate a large hot water tankused for a heat store ?

Answer:

To help answer your query, you could use something like the SUPERFOIL SF40 to wrap around the hot water tank. This product in particualr can withstand direct contact up to 70°C, and it could be furhter increased by introducing a layer of ply between them. 

Question:

Can this be used with a combination of insulation between rafters such as Kingspan or Celotex?

Answer:

Yes you can use Celotex between the rafters, and the typical method of installation for the SF40 would be under the rafters and can be stapled direct.

Question:

What tape should be used with SuperFOIL SF40?

Answer:

To ensure a consistant air-tight seal, 100mm wide foil tape should be used. We recommend SuperFOIL Superior Tape for it's high strength and enhanced adhesive which allows it to be used even in cold weather.

Question:

What size Staples do I need to fix SuperFOIL SF40?

Question:

What size Battens should I use with SuperFOIL SF40?

Answer:

Minimum of 50mm depth battens to allow the material to expand fully and maintain the required airspace for full thermal performance.

Brilliant technology, easy to install, a team of two is best option. Awaiting winter re insulation results but can already see/ feel the difference in the rooms where Sf40 has been applied. Its expensive in terms of regular insulation but is cleaner, easier to handle and requires less space with improved insulation results. If you follow the guidlines when fitting in roof rafters including celotex vapour layer and two air gaps, it should provide superior insulative properties. Tools required: An electric stapler is a must have, dont even think about using a hand stapler unless your superman. The only issue is cutting the material. Due to its multi layered design this is not easy. Dont be fooled by the sharp knife/sissors demos, you really need an electric sharp bladed tool particulaly if your job is a large one. Mine was 60 sqmtrs. These can be expensive for a one off job, can you hire one? Anyway to summerise a great product which is a one time fit given many years of superior insulation.
