Installation Guide for Celotex CW4000 Cavity Wall Insulation Board

The Celotex CW4000 Cavity Wall Insulation Board is a leading choice for professionals seeking high-performance insulation for residential, commercial, and industrial settings. Its superior thermal properties, ease of installation, and compatibility with various environments make it an ideal solution for enhancing energy efficiency and comfort. This guide provides a step-by-step overview of the installation process, ensuring a smooth and efficient application.


1. Surface Preparation: Begin with a clean, dry surface. It is crucial to ensure that the area where the Celotex CW4000 will be applied is free of debris and moisture. Accurately measure the lengths of the cavity walls where the insulation boards will be installed. A debris-free surface guarantees optimal adhesion and insulation performance.

Cutting to Size

2. Measure and Mark: Before cutting, measure and mark the insulation board according to the dimensions of the cavity wall sections. Precision is key to ensure that the boards fit perfectly, minimizing gaps and thermal bridging.

3. Cutting the Insulation Board: Use a fine-tooth saw or a sharp utility knife to cut the Celotex CW4000 board. Make sure the cuts are clean and straight to fit the measured areas accurately. Always cut on a stable, flat surface to prevent accidents.

Applying Insulation

4. Fitting the Board: Carefully place the Celotex CW4000 board into the designated cavity wall space. Ensure a snug fit to avoid gaps that could lead to thermal bridging, thus reducing the insulation's effectiveness. The precision in earlier steps will pay off here, ensuring a perfect fit.

Securing Insulation

5. Sealing the Joints: To maximize thermal efficiency, seal the seams between insulation boards using appropriate adhesive or insulation tape. This step is crucial in creating a continuous thermal barrier, enhancing the overall performance of the insulation.

Finishing Touches

6. Waterproofing and Cladding: For areas exposed to moisture or outdoor conditions, apply a waterproof finish or cladding over the Celotex CW4000 insulation boards. This not only protects the insulation from the elements but also ensures long-term durability and performance.
