Applications

K-Roc® Rainscreen Slab for rainscreen applications

Bespoke 200mm rainscreen façade systems accommodate numerous construction possibilities, combining different materials with various attachment and support mechanisms for external cladding. When fixings and supports penetrate the insulation layer to connect with the building structure, thermal bridges form. These can substantially reduce the overall thermal efficiency of your façade system. Whilst thermal isolators help minimise thermal bridging effects, the selection and positioning of fixings and supports can still increase heat transfer through the assembly, affecting the final U-value.

Kingspan K-Roc® Rainscreen Façade Insulation Slab Installation Guidelines:

• Follow the installation guidance for 200mm K-Roc® Rainscreen Slab in this section, taking into account the considerations outlined below.
• Consult your local Building Control authority to ensure compliance with current Building Regulations and Standards.
• In England and Wales, buildings classified as 'relevant' and taller than 18m require external wall membranes above ground level to achieve a minimum of Euroclass B-s3,d0.
• Since 200mm rainscreen façade systems employ proprietary designs with varied fixing and support mechanisms, consult the system manufacturer for detailed installation instructions.
