Installing a cavity closer is an essential step in the construction of a cavity wall. Cavity walls are made up of two layers of brickwork or masonry, with a gap (or cavity) between them. The cavity closer is a metal or plastic strip that is inserted into the wall to bridge the gap between the two layers of brickwork, creating a continuous air space. This air space helps to insulate the wall and prevent moisture from penetrating the building.
A poorly installed cavity closer can create several problems, including thermal bridging (where heat can escape through the gap between the two layers of brickwork), moisture ingress, and even structural issues. Therefore, it is important to follow the correct installation procedure to ensure that the cavity closer is installed correctly. Fortunately, installing a cavity closer is a straightforward process that can be completed in a few simple steps.
To begin, you will need to gather the following materials: a cavity closer, a length of galvanised wire, and a pair of pliers. You will also need to measure the width of the cavity, and cut the cavity closer to the correct length. Once you have gathered your materials, you can begin the installation process.
Step 2: Cutting the Cavity Closer to Size
Once you have marked the cavity closer, it’s time to cut it to size. Here’s a detailed guide on how to do it accurately:
4. Using a Fine-Tooth Miter Saw
A fine-tooth miter saw is the ideal tool for cutting cavity closers as it produces precise and clean cuts. Follow these steps to use it:
a. Setup the saw: Adjust the blade angle to 45 degrees and ensure the saw is set to crosscut mode.
b. Secure the closer: Place the cavity closer in the saw’s miter slot and clamp it firmly.
c. Cut the closer: Slowly lower the saw onto the closer and cut through it along the marked line.
d. Remove burrs: Once cut, use a file or sandpaper to remove any burrs or sharp edges from the cut surface.
Table: Alternative Cutting Methods
| Method | Advantages | Disadvantages |
|---|---|---|
| Handsaw | Portable, inexpensive | Less precise cuts, more time-consuming |
| Circular saw | Faster than handsaw, versatile | Requires careful handling, potential for kickback |
| Table saw | Most precise cuts, efficient for multiple cuts | Larger and more expensive setup |
How to Install a Cavity Closer
Cavity closers are used to create a cavity barrier between the inner and outer walls of a building. This helps to prevent the spread of fire and smoke in the event of a fire. Cavity closers are typically made of metal or plastic and are installed in the cavity between the two walls. Here are the steps on how to install a cavity closer:
- Locate the studs in the wall where you want to install the cavity closer.
- Cut two pieces of the cavity closer to the length of the studs.
- Bend the cavity closer so that it forms an L-shape.
- Insert the cavity closer into the cavity between the studs.
- Nail the cavity closer to the studs.
Once you have installed the cavity closer, you can continue with the installation of the drywall or siding.
