Property Insulation
Solid Wall Insulation
Most homes built before the 1920s were built with solid walls. Later on, cavity walls were used to build homes as they were seen as a way to tackle damp issues.
Solid wall insulation involves attaching a layer of insulating material to either side of a solid wall, which means it can be installed inside or outside your home.
Cavity Wall Insulation
Many cavity walls can be insulated by injecting insulation material into the cavity from the outside. A specialist company will drill holes in the outside walls, inject insulation through the holes and then seal them with cement. The insulation material is usually either mineral wool or polystyrene beads, but polyurethane foam may sometimes be used instead.
Filling cavity walls is not a job you can do yourself, you will need to employ a registered installer. A professional can do the job in around two hours for an average house with easily accessible walls. It shouldn’t make any mess.
Loft Insulation
The loft insulation has to meet the 300mm requirement so can ensure your home has the best possible protection against heat loss.
External/ Internal Wall Insulation
It is normally used to insulate solid wall properties and the surface is a protective render with decorative finish that improves the building’s appearance.
As it is installed from the outside, the insulation can be fitted without disruption to the household and the new weatherproofing will increase the lifespan of your walls by protecting brickwork.
Internal wall insulation is normally a cheaper alternative to external wall insulation and is ideal for properties where outside insulation is not suitable – such as sandstone buildings. Although it can be quite disruptive the installation can be done room by room and there are a variety of products to suit different properties.
