Bi-Fold Windows For Easy Entertaining
Bi-Fold Windows – sometimes called concertina windows – are a versatile option, giving your home a feeling of space and openness. Jason aluminium bi-fold windows are popular additions to kitchens that are connected to the outdoor entertainment area.
The Jason Bi-Fold Window range provides extra strength, thanks to the heavier aluminium frame from our commercial range. Available with:
- Sill or sill-less finish
- Three and five-panel options
Our range of bi-fold windows is built on decades of industry leading technology. For more information, explore the page or download the brochure.
