Additionally, we'll address frequently asked questions to help you understand the benefits and specifications of this superior insulation material.

Installation Process


Before commencing the installation, ensure that the surface area, such as a pipe, is clean and dry. A debris-free surface is crucial for optimal insulation performance. Accurately measure the lengths of the pipe or cavity area where the insulation will be applied. This preparatory step guarantees that the insulation fits perfectly, enhancing its efficiency.

Cutting to Size

Using a fine-tooth saw or a sharp knife, cut the Knauf DriTherm Cavity Slab 32 to the required size. It's important to measure and mark the insulation material before cutting to ensure precision. A neatly cut insulation piece will fit better around the area to be insulated, reducing the risk of gaps that can lead to thermal bridging.

Applying Insulation

Carefully open the insulation material along its slit side and place it around the pipe or within the cavity, making sure it fits snugly. This step is vital to prevent thermal bridging, which can significantly reduce the insulation's effectiveness by allowing heat to bypass the insulated area.

Securing Insulation

To maximize the insulation's efficiency, seal the seams of the insulation sections with adhesive or tape. This action ensures that the insulation acts as a continuous barrier, further enhancing its thermal performance.

Finishing Touches

For areas exposed to moisture or outdoor conditions, apply a waterproof finish or cladding over the insulation. This protective layer shields the insulation from environmental elements, prolonging its lifespan and maintaining its performance.
