Knauf Slab

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.

What are Knauf slabs?

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.

What is Knauf insulation slab used for?

You can install Knauf insulation slabs on a new build or as part of a retrofit. They are versatile and perfect for:

• Full-fill cavity wall: Dritherm slabs minimise heat loss while enhancing energy-efficient heat control.
• Internal walls and floors: They ensure there is effective sound insulation between rooms and storeys.
• Lofts and ceilings: They prevent heat from escaping through the roof.
• Commercial and industrial settings: They boost acoustic comfort and fire resistance.

Types of Knauf slabs

While there are other slab types produced by Knauf, the two most common Knauf slab ranges are Dritherm and Rocksilk.

Knauf Dritherm cavity slabs

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.

Knauf Rocksilk flexible slabs

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:

• Separating floors.
• Suspended timber ground floors.
• Internal floors and walls.
• Cold flat roofs.
• Pitched roofs (at the rafter level).
• Rainscreen facade systems.

Benefits of Knauf slab insulation

Knauf insulation slabs offer the following benefits:

1. Outstanding thermal insulation: Enjoy reduced energy usage and heating costs.
2. Excellent noise control: The slab minimises the movement of sound between rooms or floors.
3. Fire safety assurance: Knauf panels are manufactured using non-combustible materials for peace of mind and comply with fire safety regulations.
4. Moisture-resistant insulation: It resists moisture while remaining vapour permeable.
5. Easy installation: Knauf insulation is simple to cut and friction-fit for a clean, professional finish.
6. An environmentally friendly solution: It is manufactured using sustainable materials with low embodied carbon.
