The benefits of wall insulation at a glance

If you struggle to keep your home warm in winter or cool in summer, you should know a lot of heat is lost through poorly insulated walls. Wall insulation is a smart way to improve the comfort of your home and reduce your energy costs. Read on to learn about the most popular approaches and their benefits.

Uninsulated walls lose a lot of heat, which means you have to heat your home more to keep it comfortable inside. Good wall insulation provides more comfort across the board: because the temperature remains more stable, walls feel warmer in winter and stay cooler in summer. 

In addition, insulation helps to dampen sounds from outside. Moreover, good wall insulation prevents moisture from accumulating in the walls, so you greatly reduce the risk of mould and moisture damage. By installing insulation, you not only make your home more comfortable, you also contribute to lower carbon emissions.

The best method of insulation depends on the type of wall, your budget and your renovation plans. There are three popular approaches:

• Cavity wall insulation is ideal for houses with a cavity wall (usually built between 1920 and 1980). Insulation material is blown between the walls. This method is fast, simple and often the most cost-effective: it’s finished in one day with no loss of space.
• Internal wall insulation is suitable if you don't have a cavity wall or you want additional insulation. This involves fitting a false wall or insulation boards to the inside wall. All the work is done inside, but you do lose some space.
• External wall insulation is the most involved and effective process. Insulation is installed along the outside wall and finished with new cladding. This approach means you don’t lose any indoor space and offers the highest insulation value, but requires a bigger investment.

Your insulation must be installed correctly in order to avoid thermal bridges and moisture problems. That means you should always get advice from an experienced professional, especially for external and internal wall insulation.
