SEH Commercial installed 20m high REHAU Polytec 50 curtain walling and REHAU Total70 fully reversible windows in Greenlaw Court

Polytec curtain walling installed to improve thermal efficiency

  • 22 Oct 2015

REHAU’s Polytec 50 composite curtain walling system has been used in the refurbishment of an eight storey apartment block in Ealing, West London.

SEH Commercial successfully installed the 20 metre high replacement curtain walling section across the common stairwell area of Greenlaw Court.

The REHAU Polytech curtain walling was specified by Cooley Architects to match the aesthetics of the previous steel system in place, yet offer improved thermal performance and minimal requirements for maintenance.

Polytech 50 is tested to CWCT standards for weather performance and Passivhaus certified and approved.

The system uses a conventional transom/mullion construction, with box steel stick section faced internally with PVC profile and externally with aluminium.

SEH and REHAU Commercial Sales Manager Kevin O’Neill recommended REHAU Polytech50S as it could meet both the planning department’s requirement for slim sight lines and the residents association’s requirement for cost effectiveness.

In addition to the curtain walling, SEH also installed more than 130 windows in the 34 apartments in the Greenlaw Court block.

The windows were fabricated in the REHAU TOTAL 70R full reversible window system.

The curtain walling, windows and 32 balcony doors in a REHAU TOTAL70 outer frame were all fabricated by REHAU fabricator Climatec.

The refurbishment at Greenlaw Court was part of a much larger project managed by SEH which also included concrete repairs, asbestos removal, electrical and service alterations and building decoration.

The refurbishment programme has been praised by the Residents Association, both on the performance of SEH and the fact that the building is now much more air tight, with lower traffic noise and improved thermal efficiency.
