XPS Foam Insulation Boards 1200 x 600 x 10mm - Electric and Water Underfloor Heating Tile Laminate Underlay Thermal Extruded Polystyrene Insulation Sheets (10, 1200 x 600 x 10mm)

Used these to add insulation to the inside of an asbestos roof on my duck enclosure.The old roof was prone to condensation below 7°c so added these panels with a 5cm air gap between them and the roof then stuck Mylar sheets to the underside as a vapour barrier.The result was a +3°c inside temperature. Raising it from +2°c v outside to an average of +5°c.The dew point of the ceiling has changed dramatically and even in sub zero temperatures outside there is only a fine mist of condensation on the Mylar. Anything above zero and there is zero condensation.Boards were very easy to cut to size where needed, mainly scoring and snapping with a Stanley knife or where slightly more awkward shapes were needed I used a hacksaw.I sat them on screws fastened into the rafters so didn’t actually fix them but I would imagine they could be screwed carefully to a wooden surface or possibly glued or otherwise stuck to a surface as long as you used an adhesive that doesn’t damage the material.

Good quality stuff and easy to lay. Cheapest I could find anywhere by a good way.

Arrived with damaged packaging to one edge, funnily enough, it's on a protected side, not the unprotected ends, I'd suggest better protection for transit, oh, and it was delivered to No.15, not number 11! Apart from that, it looks perfect for the job in hand, which is to insulate the walls in a built in wardrobe, to stop condensation mould. I can get around the slight damage when cutting to fit, which I'm sure I'll have to. The sheets are larger than I expected, even though it does give dimensions, so will cover areas pretty quickly. The blue will stand out a bit in the wardrobe, so I may paint it in the future. I've treated the walls twice, I'm waiting for the mould block paint, coming tomorrow, then the glue on Tuesday, I'll report back once the job is done. It looks good value for money, it's thicker than foil, should insulate better, should save on heating, protect clothes and cut easily.UpdateIt cuts really easy with a craft knife and straight edge. It's stuck really well with a water based adhesive, fits really flat to the wall. So I can't really fault this product. Warning, make sure that you buy enough, I'm a sheet short I think, although I may be able to patch an inconspicuous part with the odds and sods of offcuts, which unfortunately there's not a lot of, as you can only order a minimum of 10 sheets!

These insulation boards were just the right size to fit in my kitchen with minimal cutting required. Besides that the floor is now warm enough to walk on without shoes. You have to be careful not to crush it with chair legs etc but so far it's working fine for me.

Using this for insulation between a wall and some plasterboard.Thick and easy to cut. Not flimsy at all!Seems to be doing the job in an otherwise cold room!Delivery was quick and helpful as well

I used this to line an upstairs wall that tended to get moisture forming in winter as it's an older house. Worked a treat. Also insulated the loft hatch with it in the same room. I was using a stanley knife to cut it which was quite difficult keeping it straight on a full length cut. Blade tended to wander a bit off the line. Maybe just me.

Looks good, sticks well and easy to use.

Nicely packed, arrived promptly, easy to cut & use - just mystified as the picture shows blue but is actually black!
