Cavity wall insulation is a quick way to reduce energy bills and improve the thermal efficiency of your home. But with so many options available it’s important to understand which type of insulation will be the most suitable for your property. This article will help you make the right choice for your home, so you can maximise the benefits of cavity insulation.
The first thing to consider is whether your home is suitable for insulation. A reputable professional will be able to carry out a survey of your walls before carrying out any work to establish this. This will look at the condition of your masonry and brickwork, check for damp patches, identify any faults that could be problematic or prevent the insulation from performing as expected. They will also be able to advise you on any remedial works that may be needed.
A popular form of retrofit cavity insulation is mineral wool. This is made from a mixture of natural and recycled materials and is very easy to install. It can be slid between your inner and outer walls and is often pre-cut to the exact width of your cavities, meaning it’s an extremely cost-effective option at PS10-15 per square meter (excluding labor). Mineral wool has a very favorable lambda value of around 0.034 W/mk, so it’s great for minimising heat loss and cutting heating bills.
