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.

For structural glazing, the silicone bond is part of the engineering, not just the finish.

Crystal Units can complete structural silicone bonding in controlled factory conditions, helping glazing installers and façade contractors achieve:

• Consistent structural bond lines
• Cleaner frameless finishes
• Reduced site-applied bonding
• Faster, more controlled installation
• Technical support before manufacture
• Dow Quality Bond certified capability

For qualifying projects completed under the Dow Quality Bond programme, extended 10-year warranty and application coverage may also be available, subject to Dow’s project requirements and conditions. This can include certain direct costs associated with a covered adhesive or cohesive failure.
You’re not just ordering glass. You’re working with a UK technical glazing partner focused on getting the specification, manufacture and structural bonding right before the unit reaches site.

Designed correctly. Bonded correctly. Manufactured correctly the first time.

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.

LIGHT IN. HEAT OUT.

Solar control glass is designed to reflect and absorb solar energy, reducing unwanted heat and glare from the sun while still allowing natural light into the building.

For glazing installers and façade contractors, it’s an effective solution for projects with large areas of glazing where solar gain, overheating and occupant comfort need to be considered.

☀️ Reduces unwanted solar heat gain
☀️ Helps reduce glare
☀️ Allows natural daylight through
☀️ Helps improve internal comfort
☀️ Supports more energy-efficient building design
☀️ Ideal for windows, rooflights, façades and large glazed areas

At Crystal Units, we don’t just manufacture the glass. Our technical team can help you select the right solar control coating and glazing specification for the application, helping you get the performance right before manufacture.

Control the heat. Keep the light. Specify it correctly with Crystal Units.
