Curtain Walling

Curtain walling is a method of glazing that will increase the thermal efficiency of your home and bring more light into your rooms. Sussex County Windows can install curtain walling in new builds or retro fit existing buildings.

Why choose aluminium Curtain Walling?

Curtain Walling is a thermal shop front screen and door system suitable for all types of ground floor treatment where enhanced thermal performance is required. The system is ideal for use in schools, colleges and other educational buildings.

Curtain Walling has been successfully tested to PAS 24:2012, LPS 1175 level 2 and BS EN 1627 Level 3 for enhanced security performance making the door one of the best performing fully thermally broken screen and entrance doors available in the UK. Screen work is either beaded or pocket glazed. Curtain Wall doors are weather rated to BS 6375 and are available with anti-finger trap door sections and drainable low thresholds.

All profiles feature polyamide barriers to maximise thermal performance and can be internally or externally glazed. Unlike non-thermal alternatives, Curtain Walling is available in dual colour from an extensive range of standard and non-standard finishes. Curtain Walling complies with the latest requirements of Document L for thermal transmittance.
