Understanding Fire-Safe EWI
‘Fire-safe EWI systems’ are designed to resist fire spread without compromising thermal performance. These solutions comply with Euroclass fire classification outlined in BS EN 13501-1, integrating non-combustible insulation boards, fire-rated primers like Ceresit CT16, mineral renders, and specialist fixings to create a continuous, protective façade.
Key Components
- Insulation Boards: Non-combustible stone wool or phenolic boards for high thermal resistance.
- Base Coat: Cementitious or polymer-modified layer securing insulation and minimising heat transmission.
- Reinforcement Mesh: Glass fibre mesh for crack resistance and impact protection.
- Fire Barriers: Integrated fire breaks and fixings within the EWI to compartmentalise and prevent flame spread, detailed in fire barrier guidance.
- Top Coat: Durable, non-combustible mineral or silicone finish that shields against weathering.
Benefits of Fire-Safe EWI
- Enhanced Fire Protection: Compartmentalised design slows fire spread, maximising evacuation time.
- Thermal Efficiency: Superior insulation cuts heat loss, lowering energy bills and carbon footprint.
- Weather Resistance: Robust coatings defend against moisture, wind, and UV exposure.
- Design Flexibility: Extensive colour and texture options for bespoke architectural aesthetics.
- Longevity: Minimal maintenance and extended lifespan, as outlined in EWI system properties.
- Optimised Application: Strategic tool selection, such as correctly sized trowels, ensures a uniform finish.
Installation Process
Our certified technicians follow a rigorous, step-by-step installation:
