Cavity Wall Insulation – What Type of Insulation is Best For Cavity Walls?
Cavity wall insulation is a great way to keep your home warmer and more energy efficient by reducing the amount of heat that escapes from your house through the walls. This reduces heating bills considerably over the year. It also provides a healthier, more comfortable and safer environment to live in as dampness can cause serious damage to your health.
There are several different types of insulation for cavities, each of which offer pros and cons depending on the environment and property type. For example, if you live in an area with colder climates you may need to opt for insulation with a lower thermal conductivity, known as the l-value.

The most popular choice of insulation for cavity walls is mineral wool insulation. It is flexible, easy to install, and is available in a variety of thicknesses. It is also one of the most eco-friendly options. However, if your walls are wet it can pull the beads away from the wall crevices and leave them in clumps, which means they no longer insulate effectively. It is therefore essential that your cavities are dry before insulating your home.
