Different Types of Wall Insulation

Installing wall insulation in your home is one of the best ways to increase the warmth and comfort of your home. We lose up to 30% of our heat through poorly insulated walls. The insulation will increase the heat retention ability of your walls, keeping your home warmer for longer, and reducing your energy usage and bills.

There 3 main methods of insulating your property’s walls depending on your property type and requirements.


External Wall Insulation 

External insulation involves insulation materials being applied directly to the exterior of the walls of your property. The insulation is then covered with rendering and decorative finishes. Acting as a barrier, the external insulation will retain heat inside your home while also protecting the outside from all kinds of weather conditions. External insulation increases airtightness, prevents damp and condensation and weatherproofs your home for years to come.


Cavity Wall Insulation 

A cavity wall is an external wall that consists of two rows of brick or concrete with a cavity, or space, between them. The best way to insulate these walls is to inject the insulation into this cavity from the outside. This method of insulation is a non-intrusive solution that increases the thermal performance of your walls and reduces energy costs as the amount of heat lost through the wall will fall dramatically.


Internal Insulation 

Internal insulation, also known as dry lining, involves applying insulating materials to the inner surfaces of your external walls. Usually, this means attaching an insulation board to the walls and covering it with a vapour barrier layer and plasterboard. While this is the cheapest of the wall insulation solutions it is also the most complicated to install. You will lode room space and kitchens, cabinets and other appliances will have to be taken out and refit once the installation is complete.
