From energy-saving windows to smart privacy glass, technology has transformed how we use glass at home.
Whether you’re planning a renovation, replacing windows, or upgrading interiors, understanding the different types of modern glass can help you make smarter decisions.
Below are the top five glass types that every UK homeowner should know — including when to choose
tempered safety glass for extra protection.

1. Tempered (Toughened) Glass

Tempered glass is heat-treated to make it up to five times stronger than standard glass. It’s designed to crumble into small, blunt pieces rather than sharp shards — making it ideal for areas where safety is a concern, such as doors, shower screens, and furniture tops.

• Five times stronger than ordinary glass
• Safe breakage pattern prevents injuries
• Complies with UK Building Regulations for doors and low-level glazing

2. Laminated Safety Glass

Laminated glass contains two or more glass sheets bonded with a PVB or EVA interlayer. When impacted, the glass may crack but remains attached to the interlayer — reducing injury risk and improving security. It also blocks harmful UV rays and dampens outside noise.

• Retains integrity even when cracked
• Ideal for skylights, shopfronts, and balustrades
• Provides UV and acoustic protection

3. Low-E (Low Emissivity) Glass

Low-E glass has an invisible metallic coating that reflects heat back inside the property. It keeps homes warmer in winter and cooler in summer while allowing plenty of natural light. It’s an essential upgrade for energy-efficient homes or those aiming for better EPC ratings.

• Reduces heat loss through windows
• Improves energy efficiency and comfort
• Compatible with double or triple glazing

4. Acoustic (Sound-Control) Glass

Living near traffic or busy areas can make your home noisy. Acoustic glass solves this problem with varying pane thicknesses and special interlayers that disrupt sound vibrations. It’s perfect for bedrooms, home offices, and properties in urban locations.

• Reduces external noise by up to 90%
• Available in laminated or multi-pane builds
• Works well with double glazing for extra insulation

5. Smart & Switchable Glass

Smart glass transforms from transparent to opaque at the touch of a button. Using PDLC or electrochromic technology, it provides instant privacy without blinds or curtains. It’s increasingly popular in bathrooms, offices, and luxury homes.

• Instantly changes opacity for privacy
• Energy-efficient and UV-blocking
• Stylish modern upgrade for high-end interiors
