Answers to our most common questions.
External wall insulation significantly enhances energy efficiency, reduces heating and cooling costs, improves indoor comfort, and can update the external appearance of a home.
External wall insulation offers multiple benefits:
- Energy Efficiency: By reducing heat loss in winter and heat gain in summer, external wall insulation helps maintain a more consistent indoor temperature, lowering the demand on heating and cooling systems.
- Cost Savings: Improved thermal efficiency translates to reduced energy usage, which can significantly lower utility bills. Although the initial investment is substantial, the cost savings over time can be substantial.
- Enhanced Comfort: Insulation minimizes cold spots and drafts, leading to a more comfortable living environment year-round.
- Noise Reduction: The added layer of insulation can help reduce the transmission of external noise into the home, making it quieter.
- Increased Property Value: Upgrading a home with external wall insulation can increase its market value, making it more attractive to potential buyers by improving its energy performance certificate (EPC) rating.
- Aesthetic Improvement: Modern insulation systems come with various finishes and colors, offering an opportunity to refresh the home’s exterior look during the insulation process.
- Environmental Impact: By decreasing energy consumption, external wall insulation reduces the home's carbon footprint, contributing to environmental sustainability.
These benefits make external wall insulation an advantageous choice for homeowners looking to improve their property’s efficiency and comfort.
Most homes can benefit from external wall insulation, especially those without cavity walls, such as solid brick, solid stone, or concrete panel constructions. However, suitability can depend on the home's current wall condition and any local planning restrictions.
The cost of external wall insulation typically ranges between £8,000 and £22,000 for an average-sized home, depending on the property size, insulation type, and the complexity of the installation.
External wall insulation involves applying an insulating layer to the outside of a building's walls, followed by a protective render or cladding. This enhances the building's energy efficiency, reduces heat loss, and can improve the exterior appearance.
