Silicone render is a modern, high‑performance external render designed to give properties a long‑lasting, flexible, and weather‑resistant finish. It is widely regarded as the premium choice for UK homes due to its durability and low maintenance requirements.

What Silicone Render Is

Silicone render is a thin‑coat, polymer‑enhanced render containing silicone additives. These additives improve flexibility, breathability, and water resistance, making it ideal for both new builds and refurbishments.

Key Features

• Highly flexible — reduces the risk of cracking

• Breathable — allows moisture to escape, preventing damp

• Water‑repellent — rain beads off the surface

• Self‑cleaning — dirt and algae struggle to stick

• UV‑stable — colour stays vibrant for years

• Lightweight — suitable for older walls and insulation systems

Colour & Texture Options

Silicone render is available in hundreds of colours and multiple grain sizes (1mm–3mm).
Because the colour is built into the material, it never needs painting.

Suitable Applications

• New builds

• Extensions

• Older homes needing breathable finishes

• External wall insulation (EWI)

• Commercial buildings

• Refurbishment projects

Installation Overview

1. Substrate preparation

2. Reinforced basecoat with mesh

3. Primer

4. Silicone topcoat

Lifespan

Typically 20–30+ years with minimal maintenance.

Monocouche render is a through‑colour, cement‑based render widely used for achieving a crisp, modern finish on both residential and commercial buildings.

What Monocouche Render Is

“Monocouche” means single layer in French. It is a pre‑mixed, through‑colour render applied in one or two passes, depending on the system. The colour is integrated into the material, so it does not require painting.

Key Features

• Through‑colour — no painting required

• Durable and weather‑resistant

• Suitable for large façades

• Can be scraped or textured

• Fast application compared to traditional sand/cement

• Consistent colour finish

Finish Options

• Scraped finish (most popular)

• Textured finish

• Ashlar cuts (to mimic stone blocks)

Available in a wide range of colours, typically natural tones such as white, cream, sand, and grey.

Suitable Applications

• New builds

• Extensions

• Commercial units

• Large wall areas

• Properties requiring a crisp, modern aesthetic

Installation Overview

1. Basecoat (if required)

2. Monocouche application

3. Scraping or texturing

4. Detailing (corners, reveals, ashlar cuts)

Lifespan

Typically 15–25 years, depending on exposure and maintenance.

External Wall Insulation (EWI) is a high‑performance insulation system applied to the outside of a property, then finished with a silicone render topcoat. It is one of the most effective ways to improve energy efficiency and transform the appearance of a home.

What EWI Is

EWI involves fixing insulation boards (EPS, mineral wool, or phenolic) to the external walls, then applying a reinforced basecoat and a silicone render finish.

Key Features

• Significantly improves thermal performance

• Reduces heat loss and energy bills

• Eliminates cold bridging

• Improves internal comfort

• Transforms the exterior appearance

• Adds value to the property

• Ideal for older homes without cavity walls

Insulation Types

• EPS (Expanded Polystyrene) — cost‑effective, excellent insulation

• Mineral Wool — breathable, fire‑resistant, ideal for older buildings

• Phenolic Boards — highest thermal performance

Suitable Applications

• Solid‑wall homes

• Older properties

• Homes with poor insulation

• Refurbishments

• Energy‑efficiency upgrades

• Properties undergoing external transformation

Installation Overview

1. Fixing insulation boards

2. Mechanical and adhesive fixing

3. Reinforced basecoat with mesh

4. Primer

5. Silicone render finish

Lifespan

EWI systems typically last 25+ years, depending on the insulation type and render finish.
