If your home was built after 1920 chances are it has cavity walls. These are two layers of wall with a gap between them that can be filled with insulation to improve the energy efficiency of your property. Filling cavities with insulation keeps the warm air inside and stops cold air from entering. This helps your house stay warmer for longer and reduces your energy bills. It also cuts carbon emissions, helping the environment.
The process of installing cavity wall insulation is quick and simple. Small holes are drilled into the outer layer of your house walls and insulation is blown in through these using specialist equipment. Depending on the size of your property, this can take around 2 hours. There is no mess and you will be left with a 25-year guarantee.
Generally, there are two types of insulation to choose from; mineral wool and polystyrene beads or blown cellulose. Mineral wool and polystyrene are both safe, non-allergenic and durable. They are also rot-proof and water-resistant, so you don’t have to worry about them getting wet or damaged by damp. Blown cellulose, on the other hand, is made from recycled newspaper and other materials such as shredded phone books and tax forms. It is mixed with boric acid for fire resistance and then blown into the walls through a series of holes drilled into either the inside or outside of your house walls.
If your house is suitable for cavity wall insulation, it is one of the most cost-effective energy-saving upgrades you can make. It’s a relatively cheap way to cut your heating bills and help the environment by cutting CO2 emissions, which account for a quarter of all UK greenhouse gases. Cavity wall insulation near me
