Steel Frame Direct Fix Stone Wool Clay Brick Slip A1 Rated External Wall Insulation System - External Wall Insulation System
Verified by manufacturer 10 hours ago
External wall insulation system incorporating a range of components including A1 non-combustible stone wool insulation and a clay brick slip finish.
Application
Suitable for a range of projects, including schools, student accommodation and high-rise reclad projects.
Description
External wall insulation system for steel frame substrates, incorporating an A1 non-combustible stone wool insulation board, this system achieves a system fire classification of A1 to BS EN 13501-1.
Providing a familiar brick finish with clay brick slips, it provides a cost-effective solution. The direct fix application allows the system to be directly mechanically fixed with adhesive (where required), removing the need for a cavity and the cavity fire-stopping behind the insulation.
Features and benefits:
- Direct fix.
- Durable and long lasting.
- Sustainable.
- Fire classification: A1 to EN 13501-1.
- Design life: 30 years.
- Impact resistance: Category I.
- Hygrothermal/ freeze/ thaw testing: Pass.
- Stone wool thermal conductivity: 0.036 W/mK.
- Insulation thicknesses available: 30–250 mm.
- Finish options: clay brick slips available in a variety of colours and thicknesses.
- KIWA BDA certified.
