17.5mm Toughened Laminated Glass Panels - Safety Glazing - 1087mm High

17.5mm toughened laminated glass panels for safety-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 safety: if broken, fragments stay bonded to the interlayer rather than falling free. From £130 inc VAT with 3-5 working day UK delivery.

Technical Specification

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.

Frequently Asked Questions

What is 17.5mm toughened laminated glass?
Two panes of toughened glass (typically 8mm + 8mm) bonded with a 1.52mm PVB or ionoplast interlayer to form a single 17.5mm unit. If one pane breaks, the other retains the barrier — required under BS 6180 for sole-barrier balustrade.

When must I use laminated instead of monolithic toughened?
Under BS 6180, laminated glass is required where the glass is the sole means of containment with no continuous handrail. This applies to most frameless balustrade and any edge-protection glazing without a top rail.

What panel height is available?
1087mm high — designed to achieve the required finished barrier height for balcony and landing applications when installed in a base channel or clamp system.

Can 17.5mm laminated glass be cut?
No. Like all toughened glass, laminated panels must be made to final size before the glass is tempered. They cannot be cut after manufacture.

How does 17.5mm compare to 21.5mm laminated?
17.5mm (8+8mm panes) suits domestic and light commercial sole-barrier loads. 21.5mm (10+10mm panes) handles heavier loads, taller panels and commercial applications with higher line loads.
