Certifikattyp
External wall insulation (EWI) system incorporating a range of components including A1 non-combustible stone wool insulation and a clay brick slip finish.
Applikation
Suitable for a range of projects where substrates require a drainage cavity, including retrofit, remediation, high-rise buildings, and new build.
Beskrivning
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, allowing it to be used on a building of any height.
Providing a familiar brick finish with clay brick slips, it provides a cost-effective solution. The Wetherby RagRail helps to simplify the installation of this system and provide a partially ventilated cavity.
Features and benefits:
- Small drainage holes in the base track allow moisture to escape from the system.
- 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: 80–250 mm.
- Finish options: clay brick slips available in a variety of colours and thicknesses.
- KIWA BDA certified.
