Insulation Slabs

Materials Market offers Insulation Slabs (also known as insulation batt) from established brands like Rockwool insulation and Knauf insulation. Because they are easy to install, slab insulation products are extremely popular. Most insulation slab products fit between joists or studs. Slab insulation has great thermal insulation and acoustic insulation (sound insulation) properties, they are also fire-resistant, meaning it will not ignite or spread. Slab insulation is suitable for installation in partition walls, masonry cavity walls, external walls, floors, roof spaces, and walls. It can also be used to create thermal barriers, which reduce heat loss and improve energy efficiency.
