Cavity Insulation – What Types of Cavity Insulation Are Available?

Cavity insulation is a key part of a home’s thermal and energy efficiency. It can help to keep the internal temperature stable, reduce energy bills and improve the comfort of a house, making it an ideal choice for homeowners.

There are a variety of materials that can be used for cavity wall insulation, such as mineral wool (rock wool), polystyrene beads and foam board. If a homeowner wants to choose the best material for their property, they must conduct a thorough inspection of the building structure and exterior walls in order to determine which insulation will be most appropriate. A professional can help with this process or the homeowner may choose to carry out the task themselves.

Rock (mineral) wool is a popular option for cavity wall insulation. It is made from recycled materials and offers great acoustic performance. It is also non-combustible and resistant to rot, making it one of the greener insulation options available.

Another advantage of this type of insulation is that it can easily be installed by a DIYer. However, it is important that the home owner or builder hires a trained and accredited expert to ensure the job is done correctly. This will ensure that the guarantee given by CIGA is valid and the homeowner can enjoy the benefits of this insulation for years to come.

EPS (expanded polystyrene) bead insulation is another common type of cavity wall insulation in the UK. These beads are inserted into the wall via holes that are drilled in the exterior walls. However, these types of insulation can have problems. If the beads are not bonded properly, gaps can appear which means that moisture can leak through and cause dampness in a property. insulation grant
