How Is Glass Wool Used in Cavity Wall

Glass wool is commonly used in cavity walls for insulation purposes. It is a type of thermal insulation material made from glass fibers. The glass fibers are spun into a wool-like material, which is then used to fill the cavity between the inner and outer walls of a building.

To use glass wool in a cavity wall, the following steps are typically followed:

1. Preparation: The cavity between the inner and outer walls is inspected and prepared for insulation. Any debris or obstructions are removed to ensure a clean and even surface.

2. Installation: Glass wool insulation is typically available in the form of batts or rolls. These are cut to the appropriate size and shape to fit snugly into the cavity. The insulation is then placed between the inner and outer walls, ensuring that it covers the entire area.

3. Fixing: In some cases, a mesh or netting may be used to hold the glass wool insulation in place. This helps prevent it from sagging or shifting over time.

4. Finishing: Once the glass wool insulation is installed, the cavity wall is typically finished with a vapor barrier or a plasterboard. This helps to further enhance the insulation properties and provide a finished appearance.

Glass wool insulation in cavity walls helps to reduce heat transfer, keeping the interior of the building warmer in winter and cooler in summer. It also helps to reduce noise transmission between rooms and provides fire resistance.

It is important to note that the installation of glass wool insulation should be done by professionals to ensure proper installation and safety.
