Ultra modern flush glazed, frame-free


Bifold Door Systems

GlassIIEdge™ by FSDC Global is a patented revolutionary glazing concept, which offers virtually frame-free, flush glazed doors and windows, in an array of material finishes.

This internally reinforced aluminium core system uses special patented glazing technology which allows for glazing to run edge to edge without the need for an external frame, so it’s just a flush glazed finish - pretty much like a touch screen or smartphone.

GlassIIEdge™ can be flush glazed to both sides (GG65) for an ultra modern contemporary appearance, or teamed with aluminium (AG65), and because the AG65 is a reversible design, either profile can be internal or external facing - offering options to suit existing styles, decoration and architecture and the most discerning customer.

The unique design of the GlassIIEdge™ system means no clip-in glazing beads are required in fabrication and all the glazing chambers are fully ventilated thus ensuring longevity and structural integrity of the glazed units.

All GlassIIEdge™ products are thermally insulated, have thermally insulated aluminium tracks and manufactured with highly energy efficient argon gas filled triple or quad glazing, are just as weather resistant and offer maximum security and integrity without compromise.

Suitable for both commercial and residential applications, these GlassIIEdge™ bifold doors are fitted with finger safe gaskets, durable weather seal seals, durable hardware and interlocking tongue and groove security features.

The real difference in choosing the GlassIIEdge™ system is that it achieves an ultra modern contemporary appearance with clean lines and elegance over standard products, and all of which are finished to your exacting requirements.
