Laminated

Typical make up of laminate glass

Laminated safety glass is manufactured by bonding two or more pieces of glass together using either a resin or PVB (plastic) interlayer. The most common makeup in domestic glazing is 6.8mm laminated glass, which is made up of 3mm glass/0.8mm PVB interlayer/3 mm glass.

Protection from life threatening cuts

When broken the glass stays in one piece being held together by the pvb/resin interlayer. This is the same as car windscreens and when broken, a typical ‘spiders web’ pattern results from the impact. This gives protection from cuts as the glass is in one piece.

Laminated glass can be made up of multiple glass/interlayers giving varying strengths and functions. This ranges from added security, noise control, through to ‘bullet proof’ glass.

Additional benefits of laminate glazing:

1. High-security burglar-resistant glass.
2. In conjunction with other glazing elements, reduces noise ingress.
3. Blocks up to 99% of UV rays offering furniture fade protection.
4. Offers prevention from falls in upper floor full-height glazing.

Laminate Glass in relation to Document Q and Secure by Design

Document Q is part of the UK building regulations and came into force on 1 October 2015. It applies to new-build properties and extensions. With respect to glazing, easily accessible windows and doors have the following requirement: 1 pane of the IGU must be laminated glass with the minimum classification EN356 P1A.

Similarly, Secure by Design is similar and also requires P1A glass in the same areas.

All laminated glass supplied by Regency Glass meets Document Q and Secure by Design standards.

*PVB laminated glass types cannot be used outside or in damp areas with exposed edges. This is because the PVB material is hygroscopic meaning it absorbs moisture and can result in the delamination of the glass panes.
