What is Cavity Wall Insulation?

Cavity wall insulation is a method of insulating the gap or “cavity” between the inner and outer walls of a property. It involves filling this space with an insulating material to reduce heat loss from the building, improve energy efficiency, and potentially lower heating costs. The insulation material is usually injected into the cavity through small holes drilled in the outer wall, and once installed, it helps to keep the property warmer in winter and cooler in summer by preventing the transfer of heat through the walls. Common materials used for cavity wall insulation include mineral wool, foam, and beads.

The introduction of cavity wall insulation significantly improved the thermal performance of buildings, reducing heat loss through the walls and making properties more energy efficient. This not only helped to lower heating costs for homeowners and businesses but also contributed to reducing carbon emissions by decreasing the demand for heating fuel.

Throughout the late 20th and early 21st centuries in Scotland, cavity wall insulation has continued to evolve with advancements in insulation materials and installation techniques. Today, it remains a popular and effective method for improving the energy efficiency of buildings, contributing to sustainability efforts, and enhancing comfort for occupants. However, it’s important to ensure that cavity wall insulation is installed correctly by qualified professionals to avoid any potential issues such as dampness or structural damage.

Cavity Wall Insulation Benefits

Cavity wall insulation has been shown to lower your homes loss by up to 33% as stated by the Energy Savings Trust. Professional insulation is paramount to reap the full benefits such as:

By filling the gap between the inner and outer walls of a building with insulating material, cavity wall insulation reduces heat loss during colder months and heat gain during warmer months. This leads to a more stable indoor temperature and reduced reliance on heating and cooling systems, ultimately lowering energy bills.

A well insulated home with cavity wall insulation maintains a more consistent indoor temperature, minimising cold spots and drafts. This creates a comfortable living environment for occupants throughout the year.

By decreasing the amount of energy needed to heat or cool a building, cavity wall insulation helps to lower carbon emissions associated with energy consumption. It contributes to sustainability efforts by reducing the overall environmental impact of residential and commercial properties.

While the initial cost of cavity wall insulation installation can vary depending on factors such as property size and insulation material, the long-term savings on energy bills can outweigh the upfront investment. Many homeowners and businesses experience significant reductions in both heating and cooling costs over time.

Cavity wall insulation can also help control condensation within the property by maintaining more consistent indoor temperatures. This reduces the risk of moisture buildup on interior walls, which can lead to mould and mildew growth and potential health issues for occupants.

A property with cavity wall insulation is often more attractive to prospective buyers or tenants due to its improved energy efficiency and comfort levels. It may command a higher resale or rental value compared to similar properties without insulation.
