Today’s glazing does far more than keep out the weather. With the right glass and coatings, you can boost home safety, cut energy use, and support a lower-carbon lifestyle. Below we show how modern glazing achieves both — with trusted references throughout — and when to choose tempered safety glass for added protection.

The evolution of glazing technology

UK standards and guidance now expect high performance from glass in both homes and workplaces. The
BSI Glass & Glazing knowledge hub outlines the families of standards used to demonstrate compliance with building regulations.
Manufacturers have responded with advanced product lines such as Saint-Gobain Glass (thermal, acoustic, safety and low-carbon ranges) and
Guardian Glass Low-E (explaining how low-emissivity coatings reflect heat back indoors).

How modern glazing improves safety

• Tempered (toughened) glass: Up to ~5× stronger than standard glass and designed to crumble into small blunt pieces. See the UK regulator’s guidance on glass safety at the Health & Safety Executive (HSE).
• Laminated glass: Uses a PVB/EVA interlayer to hold fragments together on impact — ideal for doors, balustrades and shopfronts.
• Fire-resistant glazing: Helps contain fire and smoke for a rated period; see official guidance in Future Homes & Buildings Standards consultation documents and Approved Documents.

For doors, low-level windows and bathrooms, upgrading to tempered safety glass is often the correct route to meet safety expectations while keeping a sleek modern look.

Sustainability advantages

Energy-efficient glazing reduces heat loss, cuts bills and lowers emissions. The
Energy Saving Trust explains how double/triple glazing and low-E coatings improve performance and comfort.
Glass is also endlessly recyclable; policy and how-to guidance are covered by WRAP’s Recycling Guidelines and its sector report on closed-loop glass roadmap.

• Thermal insulation: Low-E double/triple glazing keeps inner panes warmer, reducing condensation and draughts (see EST guidance).
• Lower carbon: Better windows reduce heating demand and help meet the UK’s efficiency targets under the evolving Future Buildings Standard.
• Recyclability: Modern flat glass can be remelted and reused without losing quality (see WRAP roadmap).

Smart materials and innovations

Coatings and constructions are getting smarter. Examples include the Pilkington Suncool™ range (high-performance solar control/low-E) and Saint-Gobain’s dedicated page on increased energy efficiency.
Pairing these with laminated or tempered safety layers yields windows that are tough, secure and energy-smart.

Frequently Asked Questions

How much can energy-efficient glazing save?
Savings vary by home and window area, but the Energy Saving Trust details typical reductions in heat loss and bills for double and triple glazing.
