Project Summary
External Wall Insulation Beckenham was installed on this large detached residential property, improving thermal efficiency while refreshing the home’s external appearance.
Project Overview
- Location: Beckenham, Bromley, South East London
- Service: External Wall Insulation
- Insulation: Expanded Polystyrene
- Property type: Large detached family house
- Use: Residential property
- Construction period: Built pre-1930
- Wall construction: Solid masonry walls (no cavity)
- Existing condition (before works): Aged and crumbling roughcast render with visible deterioration
- Issues identified prior to installation: Cold internal walls, damp patches, surface condensation and tired external appearance
- Objective: Improve thermal performance, reduce condensation issues and refresh the external appearance of the property.
- Finish Selected: Smooth, Modern, 1.5mm Silicone Render.
Technical Details
- External wall insulation system: EWI Pro system
- Insulation material: Expanded Polystyrene (EPS)
- Insulation thickness: 90mm EPS boards, selected to suit solid wall construction and improve thermal performance
- Fixing method: Combination of adhesive bonding and mechanical fixings appropriate for solid masonry substrates
- Reinforcement layer: Basecoat with embedded alkali-resistant fibreglass mesh to improve impact resistance and reduce risk of cracking
- Finish coat: Silicone render with 1.5mm grain size
- Render colour: Pure White
- Performance characteristics: Breathable, water-repellent finish designed to cope with UK weather conditions
- Mechanical Fixings: 8mm diameter, 135mm long, metal pin, hammer fixings
- Detailing: Careful treatment around openings, corners and junctions, including the installation of powder-coated aluminium window oversills to extend the existing window sills beyond the new insulation line. Oversills used were 1.2mm thick and 150mm deep, designed to maintain effective drip function and protect the façade from water run-off.
- Result: Improved insulation performance, reduced internal cold spots and condensation risk, creating a warmer, more energy-efficient and comfortable home, alongside a clean, modern external appearance
Outcome & Benefits – External Wall Insulation -Beckenham
- Significant improvement in thermal efficiency by insulating previously unprotected solid walls, reducing heat loss through the external envelope
- Creation of a warmer, more energy-efficient and comfortable living environment, with noticeably reduced cold wall surfaces
- More stable internal temperatures throughout the property, helping to improve day-to-day comfort for occupants
- Lower reliance on space heating as a result of improved insulation performance, supporting reduced energy consumption over time
- Reduction in condensation risk caused by cold internal wall surfaces, contributing to a healthier internal environment
- Complete transformation of the external appearance, replacing the old, deteriorated roughcast finish with a clean, modern silicone render
- Consistent, high-quality finish achieved across all elevations, including detailed areas such as window reveals, corners and junctions
- Durable, weather-resistant silicone render finish designed to perform reliably in UK climate conditions
- Improved protection against moisture ingress and weathering, supporting long-term performance of the façade
- Reduced risk of surface cracking through the use of reinforced basecoat and correct system detailing
- Minimal ongoing maintenance requirements compared with traditional roughcast or painted finishes
- Additional protective layer added to the existing structure, helping to preserve the building fabric of this pre-1930 solid wall property
- Overall improvement to the property’s energy performance, which may contribute positively to future EPC assessments

External Wall Insulation – Beckenham – Frequently Asked Questions
Is this a real External Wall Insulation Beckenham project?
Yes. This page documents a genuine External Wall Insulation Beckenham project completed on a large detached residential property. The photographs show real before, during and after stages of the installation carried out by our team.
What type of property was insulated on this External Wall Insulation Beckenham project?
This External Wall Insulation Beckenham project was completed on a large detached family home built before the 1930s. The property has solid masonry walls with no cavity, making it well suited to external wall insulation.
What problems did the house have before External Wall Insulation was installed?
Before External Wall Insulation Beckenham works began, the property suffered from cold internal wall surfaces, condensation issues and an old, crumbling roughcast render finish. The home also appeared tired externally.
Why is External Wall Insulation suitable for pre-1930 solid wall houses?
Pre-1930 solid wall properties do not contain cavity insulation, allowing heat to escape easily. External Wall Insulation Beckenham adds a continuous layer of insulation externally, improving thermal performance while protecting the original building fabric.
What insulation material was used on this External Wall Insulation Beckenham project?
This External Wall Insulation Beckenham project used expanded polystyrene (EPS) insulation boards. EPS is commonly used in residential external wall insulation systems due to its reliable thermal performance.
Why was 90mm EPS insulation selected for this property?
A 90mm insulation thickness was selected for this External Wall Insulation Beckenham project to significantly improve thermal efficiency while allowing window details, roof lines and boundaries to be handled correctly.
What external wall insulation system was installed?
This project was completed using an EWI Pro external wall insulation system. Using a full system approach for External Wall Insulation Beckenham ensures compatibility between all components.
Why was the EWI Pro system specified?
EWI Pro was specified for this External Wall Insulation Beckenham project because it is designed for solid wall residential properties and supports long-term durability when correctly detailed.
How were window sills handled after installing 90mm insulation?
Because External Wall Insulation Beckenham increases wall thickness, powder-coated aluminium window oversills were installed. These oversills were 1.2mm thick and 150mm deep, e
