Jablite Polystyrene Insulation board (L)2.4m (W)1.2m (T)50mm

Good product and great value

I reserved these 6 large boards and when I arrived at the store later same day they were there waiting for me on a trolley. I had misjudged the size and they wouldn't fit my car hatchback. B&Q staff were very helpful and, although cutting expanded polystyrene type material can't be done on the store floor, they found me somewhere safe to cut it in half. They also lent me thee tool to do it. Jablite very easy to work with. I stuck it to my metal shed roof using silicone sealant i had left over from a job. Looks great and no condensation drips now.

A great alternative to some of the more expensive insulations. Need twice the thickness of the foil lined stuff to pass building regs'.

Used this instead of Celotex as it was much cheaper. I lined an outside wood wall in loft to cut out the drafts, seems to have done the trick.

I used it to insulate a pond on my decking.
It was also useful to provide protection for the liner
