Rated 5 out of 5 by from Excellent Product Easy to install, yet to find out if it performs thermally. Used it in my conservertory, the roll was significantly bigger!

Rated 5 out of 5 by from Good coverage, sturdy Using this to line a loft I can only say that with two people it would have been a lot easier. Still the end result is good and the loft now has some decent insulation behind the tiles. I used 8mm staples to hold it to the roof joists and they did a good job - one roll did the top part of the roof (3 runs of 6.4m) with spare to do one of the eaves - second roll will leave a lot of spare.

Is this product fire proof?

Asked by: PlumHeatingLtd
I can confirm that the outer aluminium foils on the Airtec Double have a class 1 surface spread of flame, which basically means the foils are flame proof. The product itself however isn't fire proof, and if they was a fire in the application this product would burn also.

Wrong units for thermal resistance

W/m²K is the unit of thermal conductivity, not resistance. Thermal resistance units are m²K/W. So is 1.5 actually the thermal resistance or the thermal conductivity? This is confusing because I don't know to look for a high figure or a low one.
Asked by: nophead
Looking elsewhere I think these are R values, so the units are wrong. Higher is better. W/m²K are the units for conductivity and those are U values, generally less than one. I.e. the reciprocal of R values. Screwfix please correct your Website.

can this be used for fixing direct to inside of roof felt between roof rafters?

Asked by: Smithfield
You can't sandwich it otherwise it works against you, same as any aluminium foil insulations. You need a 5cm gap either side of it and you just staple it to the beams using 12mm staples. For radiant barriers you always need that air gap. You then just overlap it between pieces and seal it using aluminium foil tape. There are other applications but I'm not familiar with those as I only bought it to go in my loft area.

Would this work as insulation for a plastic conservatory roof?

We have a plastic conservatory roof - if I use double sided tape to line the interior with this is it likely to make the conservatory warmer or will it just cause condensation problems?
Asked by: Chillypete
I've used it to insulate ceilings. The answer for a conservatory roof is "yes you can". In order to prevent condensation, I put in the recommended 25mm air gap between the sheet and ceiling. I used a few 2x2 pieces of wood and stuck it using evo stick to the ceiling 45cm apart. Use a lot of Evo Stick or something similar so it will have a strong adhesion. I then pinned the sheet to these batons. Since the roll is lightweight it is sufficient to have the standard 25 mm x 38 mm strips of wood and they are durable. I find it preventing the conservatory from heating up like crazy in summer quiet apart from making it warmer in winters. Good luck with fixing it.
