Parallel Opening Windows

Home / Commercial Aluminium Windows / Parallel Opening Windows

A Plus Aluminium parallel opening windows are a refreshing option for architects and specifiers looking to create impact and maximise performance.

Opening along all four sides, our parallel window offers the best possible ventilation, with increased performance almost double that of a traditional casement window. Offering a fully tested window to the latest building standard is paramount to all our manufactured products.

Using aluminium profile from Sapa, we fabricate a parallel window which fully utilises its vent design; fresh air is drawn in at the bottom and stale air is expelled at the top.  This air flow promotes good circulation, maximising both high and low ventilation zones while keeping draughts to a minimum.

Our parallel opening windows are regularly installed in offices and colleges where CO2 levels need to be kept low. Easy, efficient operation of the window to place it in the open position ensures everyone can operate whilst offering maximum security.

    Sapa Dualframe 75Si Parallel Opening Window

Regulation Compliant with Colour Matching Available

The A Plus Aluminium parallel window can comply with all relevant building regulations.  As with all A Plus products, we can mix and match colours, hardware and glass options depending on requirements. We offer most RAL colours and dual specification is popular on a parallel window fitting in with other structural elements of the building.

Parallel windows can also have powered gearing fitted to provide a mechanical opening system which can also be linked to your Building Management System. Several variant positions can be set ensuring easy operation and increased ventilation.
