Wrong colour
I bought this product last month. Unfortunately it had black large specks in the boards. It wasn't a problem because I'm going to paint the boards to seal polystyrene.

This insulation was perfect
Perfect for the job I wanted it for but I would be reluctant to order again as the delivery was shocking.

Polystyrene boards on sale
Using as insulation just to stop chill on walls and roof in shed ,also put some in greenhouse over the winter stopping frost,not too thick ,easy to cut and shape,the mainly whiter boards are not as good as the black and white "more like a cow print",I found they broke too easy so when on offer I purchased all the black and white ones"cow print" they hold together better when working on them,but both very reasonable for the price,good size,and happy with them

Solid product - does the job
Bought this as a second layer of insulation in my shed after the superfoil for the ceiling, apex and floor. It is lightweight and easy to cut with a stanley blade but beware it can break under too much pressure. I would recommend collecting in a large van or having delivery as it snapped on my roof bars despite being held down by rope and bungees, but such is life. I'm not sure why people have complained in reviews about the fact it's "not white" as by it's nature jablite is meant to be out of sight as an insulating product, nor for decorative purposes, so I wouldn't let that sway your judgment. A sound product for the job I'm doing so a good rating from me!

Fine quality but not white
Quick home delivery and in good condition but definitely not "white" as described and pictured: boards had up to 10% dark blobs in meaning they would need painting, I guess at least two coats as the blobs were dark. Returning.
