How to Install Celotex Cavity Wall Insulation

If you’re wondering how to install Celotex cavity wall insulation, then read on. These instructions will help ensure that your installation is smooth and as tight as possible. First, prepare the wall surface by removing loose materials. Dry the wall surface and then prepare your insulation board. Choose between the Celotex PL4000 and GA4000 insulation boards. These boards feature an unprinted foil surface.

Before tackling the installation of Celotex cavity wall insulation, it’s important to consider the structural requirements of your building. For example, if your wall consists of a partial fill cavity made of masonry, you’ll need to use wall ties that are BBA-approved. For partial-fill cavity projects, butterfly ties are not recommended. You will also need insulation on the upper wall, preferably on a second floor.

Once you’ve got a rough idea of where you’re going to put your Celotex cavity wall insulation, you can cut it into the appropriate size. When cutting the material, make sure you wear protective gear and goggles. Celotex layer cutting is a tedious task that will produce dust and particles. Use a hand saw to minimize dust and use off-cuts for filling gaps during installation.

Once you’ve decided to install your Celotex cavity wall insulation, you’ll need to prepare the wall by ensuring that it has a standard wall tie spacing. Once you’ve measured for the wall ties, you’ll need to install a starter batten halfway up the wall, as well as a retaining channel between the insulation board and the brickwork. Once the starter batten is in place, it’s time to install the Celotex cavity wall insulation.

Installing Celotex cavity wall insulation is easy. Whether you’re installing a full cavity wall or just a portion, this product has many benefits. It has a thermal conductivity just 0.022 W/mK which will improve your home’s insulation quality and increase your comfort level.
