Maximising Energy Efficiency: The Impact of Average U-Value After Installing EWI

For 15 years, Simple Solutions 4 U has specialised in transforming properties through advanced external wall insulation (EWI) systems. Our expertise in achieving optimal average U-value after installing EWI helps homeowners and contractors significantly reduce energy costs while improving building performance.

What Is U-Value and Why Does It Matter?

U-value measures heat loss through building materials, with lower values indicating better insulation. Typical uninsulated UK solid walls have U-values of 2.1-2.7W/m²K[1][14]. After installing a 100mm EWI system, properties achieve an average U-value after installing EWI of 0.3W/m²K or lower[2][12], meeting current building regulations.

5 Key Benefits of Optimising Your U-Value With EWI

1. Dramatic Energy Cost Reductions

• 25-35% lower heating bills through improved thermal efficiency[12][14]
• £300-£500 annual savings for average semi-detached homes using winter-ready insulation materials

2. Enhanced Property Comfort

Our EWI systems eliminate cold spots and maintain consistent temperatures year-round, with internal wall surfaces staying 3-5°C warmer in winter[3][12].

3. Compliance With Building Regulations

Simple Solutions 4 U guarantees compliance, delivering average U-values after installing EWI of 0.18-0.30W/m²K using premium specialist coatings from leading brands[9][14].

4. Increased Property Value

Homes with optimised U-values see 10-15% valuation increases due to improved EPC ratings[4][12].

5. Environmental Impact Reduction

Each EWI installation prevents 1.5-2 tonnes of CO² emissions annually[12][14], supporting UK net-zero targets through eco-friendly materials.
