Knauf slab insulation is a high-performance mineral wool panel that offers all the benefits of top-tier insulation: excellent sound control, thermal efficiency and fire resistance. It is perfect for new home builds and renovations, as well as commercial constructions.
Knauf slabs are typically made from rock mineral wool or glass mineral wool. The material varies by product range. Each range is designed to offer excellent performance across acoustic, thermal and fire resistance applications.
You can install Knauf insulation slabs on a new build or as part of a retrofit. They are versatile and perfect for:
While there are other slab types produced by Knauf, the two most common Knauf slab ranges are Dritherm and Rocksilk.
The Dritherm line of panels is specially designed for cavity wall system insulation. Knauf uses glass mineral wool and an organic binder to make this class of slab insulation. They are designed for full-fill cavity wall systems, with their dense form ensuring a tight fit within the cavity.
Rocksilk Flexible is a rock mineral wool product and, as the name implies, is bendable and can easily fit in framed spacing. These slabs reduce noise while improving thermal performance across applications. They also provide excellent fire protection, which is especially useful in loft conversions. You can install Rocksilk with:
