17.5mm toughened laminated glass panels for critical glazing - balcony fall-protection, overhead canopies, juliet balconies and stairwell balustrades. All panels are 1087mm high in standard stocked widths from 500mm to 1200mm. Two sheets of toughened glass permanently bonded with a PVB interlayer for combined strength and post-breakage integrity: if broken, fragments stay bonded to the interlayer rather than falling free. With 3-5 working day UK delivery.

Why Toughened Laminated Glass
Laminated glass is two or more sheets of glass permanently bonded together with a polymer interlayer (PVB) using heat and pressure. When both sheets are also toughened (as here), you get the impact strength of toughened glass with the post-breakage integrity of lamination. Under sufficient force the glass will still break, but the fragments stay bonded to the PVB interlayer rather than falling free - the panel stays largely in place and the risk of injury from falling glass is sharply reduced.
This is what makes laminated glass the standard choice for overhead glazing (canopies, skylights, roof lights), balcony fall-protection on upper floors, and structural glazing - anywhere broken glass could cause serious harm. Toughened glass on its own can shower out completely on impact, which is unsafe in these applications. Laminated also offers improved acoustic insulation and security against forced entry compared to single-pane toughened.
Common Uses
Balcony fall-protection on upper floors, juliet balconies, overhead glazing (canopies, skylights, roof glass), structural glass walls and partitions, stairwell and atrium balustrades, security glazing for ground-floor windows and shopfronts, and acoustic glazing where sound reduction matters.
