Where to buy polystyrene sheets?

[Elmo]

As title says, Im looking for some poly sheets to cover an area approx 3.1 x 1.9. So 2 std size sheets basically.

Yes Ive looked on TM, and they sell 25mm at a good price, but Im looking for thinner, say 5/8 or 3/4 even.

Does anyone have any ideas where to get it, or even have any hook ups?

Go see these guys http://www.longplastics.co.nz/

Will make any size you require. Cheaper than buying from retail stores also.

How about 10mm or so thick? Does it need to be in one piece and how soon do you need it? Some cookers we install come with about 6 sheets at something like 6-700 by about 900mm. I can save them when we come across them if wanted. Let me know if that will suit or not.

Thanks Luke, but I think Ive found a product much better than poly, and its only 5 mm thick, has an R rating of 1, which is massive compared to poly of even twice as thick. Otherwise what you are suggesting would be quite good.

All good, what's it for?

[Elmo]

Insulation in roof of a pop top camper that we just got. Need to tidy it up a bit.

Ah sweet

If the 5mm stuff doesn't work out just let me know. Whatever is used, i'd be a bit concerned about moisture / condensation forming. Unless the roof isn't metal anyway.

[Elmo]

Yeah we have talked about condensation in there. The roof is thin ali.

Ah should be all good then rust wise

Can I ask what the product is that you have found? I may also be in need of something to suit a small gap. Cheers.

Its basically bubble wrap with each side covered in tin foil. Has an r rating of 1 (= to 40mm of poly) and is approx 5mm thick, and is flexible.

Ah, so a DIY deal or legit product I can tell someone to install?

[Elmo]

To be honest I dont know. I know its not a back yard deal, I got the stuff from
