The Stove Wizard Fire Board Heat Proof Insulating Calcium Silicate Board 4 Bricks 1832°F 1000°C Insulate Flame Retardant, High Temperature Insulation Ceramic Fibre Thermal Insulation Board Grey Skamol

good product although slimmer than real brick but would put that down to me not checking the size

What a waste of money haven't lasted long as soon as the heat gets to them they cracked then when heat was on for long period of time they started to crumble into little pieces. Have had to order another lot of panels to replace these. Not worth the money they cost not even worth a 1 star rating.

The product itself seems to do its job, stops heat passing through it so is an ideal barrier. But sadly each slab had what appeared to be remnants of tape stuck to them which meant each item needed cleaning prior to use. It does cut with a Stanley knife but isn't the cleanest of cuts - it would likely work best with a jigsaw (although may crack). It's worth noting when cutting them they create substantial mess and dust so be aware.

Delivery happened earlier than stated which we appreciate, great service. Good product

These were bought urgently as the correct ones haf a delay in delivery tme . Pretty hopeless cracked and fell apart within a couple of days useage . Would not buy again

I used these to line a wood stove, they cracked into peices after 3 nights. Don't waste your money, buy vermiculite.
