External Wall Insulation

At Shape Up, we’re passionate about helping homeowners improve their energy efficiency while enhancing the look of their homes. External wall insulation is a transformative solution that offers comfort, savings, and style in one comprehensive upgrade.

This renovation can reduce heat loss, protect your walls, and save you up to 35% on energy bills. Plus, with a variety of finishes available, it’s an opportunity to refresh your home’s exterior while making it more eco-friendly and comfortable.

What Is External Wall Insulation?

External wall insulation involves adding a layer of insulating material to your home’s outer walls. This layer traps heat inside during winter and keeps it out during summer, improving your home’s thermal performance. At the same time, it protects your walls from weather damage and reduces the risk of damp and mould.

By choosing external wall insulation from Shape Up, you can enjoy a home that’s not only warmer but also more energy-efficient and visually appealing.

Benefits of External Wall Insulation

External wall insulation offers numerous advantages that make it a smart investment for any homeowner.

Energy Savings

External wall insulation can slash your energy bills by up to 40%, making your home more cost-efficient to run. By reducing heat loss in winter and minimising heat gain in summer, it ensures your heating and cooling systems work less, saving you money year-round.

Protection and Comfort

  • Weather Resistance: Shields your walls from rain, frost, and wind, reducing wear and tear.
  • Moisture Control: Helps prevent damp and mould issues, improving indoor air quality.
  • Comfort: Keeps your home warm in winter and cool in summer, creating a more pleasant living environment.

Enhanced Aesthetics

External wall insulation is available in a wide range of finishes, from smooth renders to brick effects. Whether you want a modern look or a classic style, you can choose a finish that complements your home. It’s also a great way to cover up outdated or unsightly brickwork.

Increased Property Value

Energy-efficient homes are in high demand. Installing external wall insulation can increase your property’s value, making it more attractive to potential buyers.

Materials Commonly Used

Different insulation materials offer unique benefits. Here are some common options:

  • Expanded Polystyrene (EPS): Lightweight, affordable, and easy to install.
  • Mineral Wool: Fire-resistant and excellent for soundproofing.
  • Phenolic Foam: Thin but highly effective insulation.
  • Wood Fibre: Eco-friendly with good breathability.

The insulation is typically covered with render or cladding, available in a variety of colours and textures to match your preferences.

Analysing the Costs

While external wall insulation requires an upfront investment, the long-term savings and benefits make it worthwhile.

Initial Investment

For a typical three-bedroom semi-detached house, installation costs range from £10,000 to £20,000. The final price depends on:

  • The size of your home.
  • The type of insulation material.
  • The complexity of the job.

Material costs vary:

  • Expanded Polystyrene (EPS): £45-£55 per square metre.
  • Mineral Wool: £55-£65 per square metre.
  • Phenolic Foam: £65-£75 per square metre.

Additional costs, such as decorative finishes, trims, and windowsills, should also be factored in.

Long-Term Savings

External wall insulation can save you £300-£500 annually on energy bills. The exact savings depend on factors like your home’s size, existing insulation, and energy usage habits. Homes with poor insulation will see the biggest benefits.
