Description

Spectus curtain walling is based on frame of aluminium mullions which is supported from the floor slabs and transoms.

This system can accommodate the full range of Spectus 70 mm windows and doors for a wider choice of product, and to make replacement of individual glazed units easier in the event of damage or breakage. Specifiers can choose from direct glaze insulation or spandrel panels, if in the unlikely event a glazed unit does need to be replaced, the system accepts individual glazed frames.

The bead is simply removed and the new glass unit slotted in from the inside, for a simple and quick replacement.

The curtain wall system is PVC-U clad; both internally and externally, ensuring colour and material matches for an attractive end result. Window frames, cover caps and cladding panels are fitted post installation minimizing site damage.
