INFORMATION
THERMAL PERFORMANCE
Rainscreen façade systems are bespoke and configuration and specification of those systems are specific to individual buildings. System supports and fixings will have an effect on the thermal performance of that system. Thermal performances and patterns of fixings should be sought from the system manufacturer or supplier. Advice given in BR443 'Conventions for U-Value Calculation' should be followed.
KEY POINT
- Superior Performance Phenolic Insulation
- Euroclass B -s1 d0 Fire Classification
- Lower Lambda values for improved U-Values
- Tested and Approved under BS 8414
- Meets criteria of BR135
