Wall Insulation

Wall insulation is generally applied in three distinct ways. Insulation can be installed in a cavity wall, on the exterior of the building, or in an interior wall. While cavity wall insulation is usually considered the most efficient of the three, it’s not always a practical or possible solution. Both external and internal applications have their benefits and will work to retain heat and lower household bills.

Wall Insulation

Reducing the energy needed to keep your home warm could be as simple as insulating your walls. Most homeowners are losing around 35% of the heat in their homes through the walls.

Insulating your home is a way to solve this, although the materials and technique you’ll need will depend on the type of wall you are going to insulate.

Cavity Wall Insulation – most homes built after 1920 have walls made of two layers. This gap prevents water getting in but contributes to heat loss. This type of insulation will either be mineral wool, PIR boards or phenolic boards.

Solid External Wall Insulation – solid walls are usually found in older homes. Insulation can make your home more energy efficient, prevent draughts and there won’t be disruption to your home while it’s being insulated as it is fitted to the outside of the house.

Internal Stud Wall Insulation – Stud walls are constructed from a frame of vertical timber beams and various materials can be packed between or applied over the top to insulate those walls. You could also consider acoustic insulation to dampen noise elsewhere in the home.
