Excellent reflective foil
20 Aug 2014
By
, Kent
"This product is basically a strong version of bubble wrap with a highly reflective plasticised foil facing on both sides.
When used correctly, it is a very effective performer against heat loss.
It is not my first time of use and I will almost certainly use it again.
I have seen the product weight described as 505 kg. If you notice this, it would probably be best not to attach too much value to it."

Strong and flexible
18 Nov 2013
By
, Nunthorpe
"Very easy to use product and does what it says on the tin. unfortunately the glue used to keep it into a roll was to strong and took the foil with it lost 200mm of each roll, but screw fix sorted this with another roll. Would recommend this product to everyone, so flexible and easy to cut."

"This was needed for a fish room build where every inch of space was needed so this suited alot better than celotex or kingspan.
At the price it is i wasn't expecting it to work but to my surprise it worked greatly!
I have already noticed a decrease in my electricity bill and can feel the heat blow me away when i enter the room!
Really is great and i will be buying more very soon.
Try it for yourself!

versatile product
19 Nov 2012

"the wrap is only 6mm thick therefore can be used for surfaces such as loft access door where there is restricted space and a need for a good fix is required (double sided tape used). It has an advertised insulation value equivalent to 50mm poly which is good for any area where conventional and thicker insulation will not fit. Easy to work with and quite robust, keep away from sharp items that may puncture the surface but otherwise easy to form into shapes to wrap joists or other awkward surfaces.
I have made sure it is away from TV antena, just in case the high reflective foil surface interferes with signal.

Best garage door insulation
17 Jun 2014
By
, Northumberland
"Bought this product to insulate the inside of a metal up and over garage door. The insulation was easy to fit, sliding between the struts on the back of the door to hold it in place, cutting around the lock etc. Joints sealed with aluminium tape for a professional look.
The insulation HAS made a difference. In the winter months there is now condensation on the outside of the garage door (as you get with A-rated glass) and the garage itself does not get as cold when left unheated. When using it to work in, the garage warms up much faster and retains heat for longer.
This is great value retrofit insulation for metal up and over garage doors.

"the insulation is noticeable, you can feel the heat being reflected back at whilst you work, and added bonus it makes working with a trailer lamp some much easier as it reflects the lamp light every where.
Rolls out Easy, only needs paper staples to hold it in place....
liked it so much i went and bought more!

"... needed to creat barrier between brickwork on north face and lath-mounted plasterboard, wanted to have a bit of insulating benefit and mitigate against any damp. This seems ideal, easy to work with, not sure claim of equivalence to 55mm is credible but I guess it must be - doesn't feel it to touch but that may be because surface is foil and feel cold initially, soon warms up though, must have looked stupid as I put my cheek against the wall to check!!
PS No-one was watching!"

"...be careful if installing in front of a loft aerial - it can play havoc with the Freeview TV reception on some channels."

"Small point but is worth making:
Screwfix uses m²/kW for thermal resistance units which reads as square metres per kilowatt. The SI unit is m²K/W or square metre Kelvin per watt which is quite a different thing. Anyway to keep it simple this R unit is the inverse of the old 'U' one and the bigger the 'R' the better but be careful when sellers quote.

Insulation Performance WRONG
23 Apr 2010
By
, Whiltshire
"Performance Warning. The Screwfix product description states the product has an insulation value the same as 55mm of polystyrene, it does not. The Screwfix description fails to tell you that this level of performance is only possible if used in conjunction with a large air gap and that most of the performance, (nearly all performance) comes from the large air gap. This is not mentioned at all in the Screwfix product description, the product its self has little insulation performance or R value. The product description as provided by Screwfix does not fully inform the buyer about the claims made. You will not achieve anywhere near this level of performance unless you use this product to create a large sealed airgap. This is the same for all bubble foil insulations. This item is very high priced for the kind of product it is and buyers should check the real ££££ value by comparing real performance."
