Cavity Wall Insulation vs. External Wall Insulation

Cavity Wall Insulation vs. External Wall Insulation

When it comes to improving energy efficiency and reducing heat loss in your property, choosing between cavity wall insulation (CWI) and external wall insulation (EWI) can be challenging. Both methods have their merits, but understanding their differences is key to making the right decision.

Cavity Wall Insulation: Benefits and Drawbacks

Cavity wall insulation involves filling the gap between two layers of brickwork with insulating material, such as mineral wool or foam. It’s a cost-effective solution for homes with unfilled cavity walls and can significantly reduce heat loss.

Benefits:

  • Cost-Effective: Generally cheaper than EWI.
  • Quick Installation: Minimal disruption to your home during the process.
  • Improved Energy Efficiency: Helps lower heating bills and reduces carbon emissions.

Drawbacks:

  • Not Suitable for All Homes: Older properties with solid walls or narrow cavities may not be compatible.
  • Potential Damp Issues: Poorly installed insulation can cause moisture to bridge the cavity, leading to damp problems.
  • Limited Thermal Efficiency: May not achieve the same level of performance as EWI.

External Wall Insulation: Benefits and Drawbacks

External wall insulation involves fixing insulating panels to the outside of your property and finishing with a protective render or cladding. This method is ideal for solid wall properties or homes where cavity wall insulation isn’t an option.

Benefits:

  • Enhanced Thermal Performance: Offers superior insulation and significantly improves the U-value of your walls.
  • Reduced Damp Risk: Acts as a protective barrier against rain penetration.
  • Aesthetic Improvement: Gives your property a fresh, modern look.

Drawbacks:

  • Higher Cost: Installation is more expensive than CWI.
  • Planning Permission: May require approval in conservation areas or for listed buildings.
  • Longer Installation Time: The process can be more disruptive and time-consuming.
