Rockwool RW3 50mm Slabs Storage & Handling

RW3 50mm slabs have a soft, fibrous texture, very similar to a loaf of bread. Because of this, a serrated blade is all you need to slice through it. We recommend marking the dimensions you need on your slab to avoid mistakes.
When it comes to storage, we advise that you store the slabs inside in a cool, dry area.
