Verified by manufacturer 10 hours ago
External wall insulation system incorporating a range of components including A1 non-combustible stone wool insulation and an acrylic 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 A2-s1,d0 to BS EN 13501-1, allowing it to be used on a building of any height.
Providing a classic brick appearance with acrylic brick slips, it provides a flexible, robust and 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.
- Flexible – suitable for curved substrates.
- Quick to install.
- Lightweight.
- Fire classification: A2-s1,d0 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: acrylic brick slips available in a variety of colours.
- KIWA BDA certified.
