Infinity works with trusted external wall insulation and render system partners to deliver durable, energy-efficient finishes for homes across London.
What is External Wall Insulation?
External wall insulation involves applying an insulating layer to the exterior of your home's walls, followed by a protective render or cladding. This method improves thermal efficiency by reducing heat transfer, making it especially effective for older properties with solid walls that lack cavity insulation.

- Improved Comfort: Keeps indoor temperatures steady year-round.

Our Working Process
How we deliver your external wall insulation, step by step:
Free Home Survey
We visit your property to assess suitability, measure wall areas, and confirm the best insulation system and render finish for your home.
Customised Work Plan
We provide a detailed, tailored plan covering materials, timescales, and costs.
Surface Preparation
Our team cleans and repairs the exterior wall surface, fixing any cracks or defects to ensure a solid base for the insulation system.
Insulation Board Installation
EPS or XPS insulation boards are fixed to the wall using adhesive and mechanical fixings, creating a continuous thermal envelope.
Basecoat and Reinforcement Mesh
A two-layer basecoat is applied with embedded fibreglass reinforcement mesh to strengthen the system and prevent surface cracking.
Render Finish and Handover
Silicon primer is applied, followed by your chosen topcoat - smooth, mosaic, or silicon render - for a durable, weather-resistant finish.
