Can these be layered and used to hold up a fish tank? Or will they compress/breakdown from the weight?

I think they would be too flimsy and light to bear the weight of a fish tank full of water. There are a lot of airholes in these sheets. You would need a denser type of polystyrene foam for your purpose.

Can these be cut to a custom size by the seller?

I bought this product for my railway layout. For a hillside effect. I was able to cut it, to the right sizes I needed for my layout.Very easy to cut.

What are the products fire safety details? Is it fire resistant?

Hi there,,These sheets adhere to current building regulations.

Could I use this to insulate heat from a reptile heat mat so that the heat is projected into the habitat?

it depends if you want just insulation then yes, however, if you are looking to reflect heat into the habitat I would recommend something like a space blanket like this https://www.amazon.co.uk/Am-Tech-Emergency-Blanket-2-Pieces/dp/B005CRVKXW/ref=sr_1_2?ie=UTF8&qid=1513782943&sr=8-2&keywords=space+blankets

polystyrene Foam Sheets

Great product. Ideal for insulating loft access door. Slices easily with a sharp knife and fitted accurately into wooden frame with a few spots of glue. Very quick delivery and a fair price. Arrived undamaged but delivery in a plastic bag does not protect against knocks during transportation. Luckily, I had no problem.

Is ok for packing boxes, but little else.

Is ok for packing boxes, but little else. Had hoped to use for insulation but discovered not fireproof. Probably my fault for not fully investigating. Can't tho give it more than 3 stars.

Good Value Polystyrene Foam for Insulation

This is good value polystyrene foam that I used to insulate my attic lid. It was good quality, worked well and I was able to cut it to size easily.

Very useful blocks to protect items in transit.

Very useful blocks - we bought these to add additional protection to a fragile item that we were posting off for repair inside a large cardboard box.
