EWI vs Cavity Wall Insulation: A Comprehensive Guide
With 15 years of expertise in renders, plasters, and external wall insulation (EWI) systems, Simple Solutions 4 U helps homeowners and contractors make informed decisions about energy-efficient upgrades. This guide explores the critical differences between EWI vs cavity wall insulation, empowering you to choose the right solution for your property.
Understanding EWI vs Cavity Wall Insulation
Both systems aim to reduce heat loss, but their applications differ significantly:
| Feature | EWI | Cavity Wall Insulation |
|---|---|---|
| Installation Area | Exterior surfaces | Wall cavity gap |
| Wall Compatibility | Solid or cavity walls | Cavity walls only |
| Insulation Thickness | Up to 200mm | Limited by cavity width |
5 Advantages of EWI Over Cavity Wall Insulation
- Superior thermal performance (up to 35% greater energy savings)
- Eliminates cold bridging and damp risks
- Enhances exterior aesthetics with decorative finishes
- Adds weatherproofing and structural protection
- Increases property value
When to Choose Cavity Wall Insulation
While EWI offers numerous benefits, cavity wall insulation remains a viable option for:
- Post-1920s homes with unfilled cavities
- Budget-conscious projects
- Properties in conservation areas with facade restrictions
Case Study: Combining Both Systems
