About Our Optio 58BW Commercial AW620 Sash

Featuring industry-leading build quality, our 58BW ST aluminium windows are an ideal replacement for existing steel windows. In addition to impressive high thermal and acoustic performance, the design also replicates the minimal sight lines associated with steel windows, whilst providing superior performance and security. Yet another win-win.

Our aluminium commercial sash windows can be internally or externally glazed depending on your project specifications, and are available with either 24mm or 32mm glazing. They are compatible with a range of configurations including top hung, side hung, and fixed light, and can be finished with a single or dual colour powder coat paint.
