Understanding Toughened Glass and Safety Glass: Essential Choices for Modern Applications
In today’s architecture, construction, and interior design industries, toughened glass and safety glass are among the most sought-after materials for projects demanding strength, durability, and protection. Whether you’re renovating a home, designing commercial spaces, or specifying glass for residential projects, choosing the right type of safety glass ensures compliance with building regulations while enhancing aesthetics and security. At The Glass Supplier, we specialise in supplying premium toughened glass, tempered safety glass, and laminated safety glass cut to size and delivered nationwide.
What is Toughened Glass (Tempered Glass)?
Toughened glass, also known as tempered glass, is produced by heating standard float glass to approximately 620°C and then rapidly cooling it with high-pressure air blasts. This thermal tempering process creates high surface compression and edge strength, making the glass up to five times stronger than untreated annealed glass of the same thickness.
The most important safety feature of toughened glass is its break pattern. When it fractures into small, granular pieces rather than sharp jagged shards, dramatically reducing the risk of serious injury. This characteristic is why toughened glass is classified as a safety glass under British Standard BS EN 12150 and is mandatory in many applications including shower screens, balustrades, glass doors, tabletops, and building facades.
Popular thicknesses for toughened glass range from 6mm to 19mm, with 10mm and 12mm being especially common for frameless shower screens and balustrade glazing. We stock clear, low-iron (ultra-clear), tinted, and some patterned toughened glass options, all processed here in the UK, to exact specifications.
What is Laminated Safety Glass?
Laminated safety glass consists of two or more layers of glass bonded together with a tough polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) interlayer. When impacted, the glass may crack, but the interlayer holds the fragments in place, preventing the panel from collapsing and creating a “spider-web” cracking pattern.
This retention property makes laminated glass the preferred choice where fall protection or security resistance is critical. It is required by building regulations in overhead glazing, rooflights, balconies, and full-height windows in domestic properties. Laminated glass also provides excellent acoustic insulation and UV filtration (blocking up to 99% of harmful rays), making it ideal for conservatories, office partitions, and museums.
We supply clear laminated safety glass in various configurations: 6.4mm (two layers of 3mm), 8.8mm, 10.8mm, right up to 21.5mm and thicker for toughened lamiante glass options; enhanced security or acoustic performance. Common options include clear, obscure, tinted, and even coloured interlayers for decorative effects.
Key Differences Between Toughened and Laminated Glass
- Strength & Breakage: Toughened glass is stronger and shatters into small pieces; laminated glass holds together when broken.
- Processing: Toughened glass cannot be cut or drilled after tempering; laminated glass can be supplied toughened and laminated for maximum safety (often called toughened laminated glass).
- Applications: Toughened for vertical screens and doors; laminated for overhead, security, and noise-reduction needs.
- Cost: Toughened is generally more economical; laminated offers superior security and soundproofing at a higher price point.
Many modern projects now specify toughened laminated safety glass – combining both processes to meet the strictest safety requirements.
Why Choose Toughened or Laminated Safety Glass?
- Superior Safety – Minimises injury risk and complies with UK building regulations.
- Increased Security – Laminated versions resist forced entry far longer than standard glass.
- Noise Reduction – Acoustic laminated glass can reduce external noise by up to 50%.
- UV Protection – Protects furnishings, artwork, and flooring from fading.
- Thermal Performance – Easily combined with low-E coatings for energy-efficient double glazing.
- Aesthetic Versatility – Available in ultra-clear, frosted, sandblasted, printed, or coloured finishes.
