HERITAGE STYLE. MODERN PERFORMANCE. FACTORY FINISHED.

Heritage-style glass doors need the right balance of traditional appearance, modern glazing performance and a clean, consistent finish.

Crystal Units can manufacture insulated glass units with aluminium fenestration glazing bars factory-applied before the glass reaches site, with precision lock plate cut-outs and other specialist processing completed as part of the manufacture.

For window manufacturers and glazing installers, that means:

• Less time fitting glazing bars on site
• Reduced installation labour
• Precision lock plate cut-outs ready for door hardware
• More consistent bar positioning and alignment
• Cleaner, controlled factory finishing
• Fewer components and processes to manage on site
• Reduced risk of remedial work and call-backs
• Modern high-performance glazing with a traditional heritage appearance

With the glazing bars and specialist glass processing completed before delivery, your team can focus on installing the finished unit rather than carrying out additional fabrication on site.

Crystal Units can also help specify the right glass build-up, coatings and performance requirements for the application, helping ensure the complete unit is designed correctly before manufacture.

Save time on site. Reduce labour. Get the details right before installation.

A big thank you to the Future Facade Forum 2026 team for a fantastic event yesterday at The Building Centre in London.

It was great to spend the afternoon with professionals from across the construction and façade sectors, sharing ideas, technical insight and perspectives on how façade design and performance continue to evolve.

Events like this are a valuable opportunity to connect with others across the industry, discuss the challenges facing modern building envelopes and explore the role innovative glazing solutions can play in delivering better-performing buildings.

Thank you to everyone involved in organising the event, and to fellow sponsors Technal UK, Guardian, Thorp Precast, Siderise and GGR Group for supporting an excellent afternoon.

Crystal Units is proud to be part of the conversation around the future of façades, bringing technical glazing expertise, specialist manufacturing and advanced glass solutions to projects across the UK.

NO FRAMES. NO VISIBLE FIXINGS. JUST GLASS.

Solar Control Glass. Proven on Iconic UK Projects

Balfron Tower is an iconic Grade II-listed Brutalist building designed by Ernő Goldfinger in the 1960s.

Its refurbishment presented a complex glazing challenge: improve thermal performance, airtightness and occupant comfort while respecting the original fenestration patterns, slim sightlines and architectural character of the building.

The solution included high-performance double-glazed IGUs incorporating solar control glass, helping to reduce unwanted solar gain while improving insulation and supporting the building’s long-term energy performance.

It’s exactly the type of project where getting the glass specification right matters.

WHY CRYSTAL UNITS?

For glazing installers, window manufacturers and façade contractors, we offer more than glass manufacturing.

✓ Technical support before manufacture
✓ Solar control and coated glass expertise
✓ Advice on U-values, g-values and thermal performance
✓ Glass thickness and loading calculations
✓ Complex and bespoke IGU manufacturing
✓ Support for heritage and specialist glazing
✓ UK manufacturing
✓ Over 30 years of glazing expertise

From heritage refurbishments like Balfron Tower to modern commercial façades, we help make sure the glazing is designed correctly before it reaches production.

The right glass. The right specification. Manufactured correctly the first time.

SOLAR CONTROL GLASS. CONTROL THE HEAT, NOT THE LIGHT. ☀️

When you’re specifying glazing for façades, curtain walling, rooflights or large glazed areas, managing solar gain is critical.

Solar control glass is engineered to control how solar energy is transmitted, reflected and absorbed, reducing unwanted heat gain and glare while maintaining high levels of natural daylight.

Depending on the specification, specialist solar control and Low-E coatings can help manage infrared and UV radiation while allowing visible light to pass through. Within an IGU, the coating position and overall glass make-up are selected to achieve the required performance.

For glazing installers and façade contractors, getting that specification right matters.

At Crystal Units, our technical team can help you select the right glass and coating combination for the application, considering factors including:

• Solar gain and g-value
• Light transmission
• U-value and thermal performance
• Glare reduction
• Glass thickness and loading requirements
• IGU configuration
• Solar control coatings
• Ceramic border requirements on coated glass

The result is glazing designed around the performance requirements of the project, not simply manufactured to an order.
