I over ordered due to the long lead time on the HardRock®. I didn't want to delay our build at a critical time and so ended up with a pallet of 12 boards left over.

It has been stored inside, and has been kept dry but had a few knocks moving it around.

It's not been used, but has been stored for a while whilst we finished the secondary project and until I knew it was surplus.

It's a great product. It can be used to create a warm room and when combined with Rockwool Flexi creates Rockwool Rockfall system. A very energy efficient heat and sound insulation system. (I may have some Flexi available too).

Can be used on a flat or pitched roof.

This is the perfect amount for an extension project to achieve good energy efficiency and avoid the lead times.

Due to the size it's collection only. The price is for the whole pallet of 12 sheets.
