Architects have long pushed for wider openings, finer sightlines and fewer interruptions between inside and out. But conventional sash construction eventually reaches a physical limit: the glass still needs space around it, and that space becomes visible aluminium.

TITAN Bonded Sashes change the arrangement itself—moving the glass to the external face and allowing the glass and aluminium to work together structurally.

The TITAN Bonded Sash places the glass on the external face of an aluminium profile, joining the two with a structural adhesive. This removes the conventional internal glazing pocket and perimeter packers, reducing visible aluminium around the sash by up to 30%, depending on the surrounding system.

From the outside, the glass and sash form a clean, flush plane. The glass runs closer to the edge and the aluminium becomes less prominent. Across several panels, the elevation reads more continuously. Operable sections sit more naturally beside fixed glazing, and the eye is drawn through the opening rather than around each sash.

That visual difference is only part of the story.

Our mitred corners reflect meticulous craftsmanship and attention to detail, ensuring beautifully seamless Bi-fold door panels. With a thoughtfully engineered 43mm sash depth, this design not only delivers a refined, luxurious appearance, but also enhances performance—eliminating gaps, leaks, and distracting noises common with traditional butt joints.

The result is effortless elegance and a pristine look, free from accumulating leaves or dirt, truly elevating the style and comfort of your space.
