Why Homeowners Choose External Wall Insulation in Bromley
Many properties in Bromley are solid-wall homes that lose heat through external walls. External Wall Insulation (EWI) is the most effective way to improve thermal performance, reduce energy bills, and upgrade the exterior appearance at the same time.
- Lower heating bills – significantly reduces heat loss through solid walls
- Warmer, more comfortable home – consistent internal temperatures year-round
- Improved appearance – modern, clean rendered finishes in your chosen colour
- Protection from damp & weather – breathable systems help manage moisture
- No loss of internal space – insulation is applied externally
- Long-term investment – durable systems designed to last 30+ years
Our fabric-first approach to energy efficiency means we prioritise reducing heat loss at the building envelope before recommending other measures — delivering real, measurable improvements for Bromley homeowners.
Our External Wall Insulation System
All our External Wall Insulation in Bromley installations follow a proven, system-based approach using certified materials and correct detailing. Each system is selected to suit the property type, wall construction, exposure conditions, and desired finish.
- Insulation boards: EPS (Expanded Polystyrene), Mineral Wool or Kingspan K5
- Fixing method: Adhesively bonded and mechanically fixed for long-term stability
- Reinforcement: Full fibre mesh embedded into reinforced basecoat
- Basecoat: Leveled and floated to create a stable, even background
- Primer: Applied to ensure consistent suction and colour uniformity
- Finish coat: Silicone, acrylic, mineral or self-cleaning render options
- Colour options: Wide range of durable, colour-fast finishes available
Careful detailing is carried out around windows, doors, corners, plinths and junctions to ensure weather resistance, visual consistency and long-term durability. Where required, extended aluminium window oversills are installed to maintain correct water run-off after insulation thickness is added.
This system-based approach delivers a warm, energy-efficient and weather-protected home, finished to a high standard and designed to perform reliably in UK conditions.

Will external wall insulation affect the appearance of my home?
No — it will enhance it! With modern finishes like silicone render, acrylic render, or self-cleaning render, your home will look cleaner, sharper, and more modern while benefiting from improved insulation.
