Up and Over Glazing Glass

Up and over glazing is one of the most striking architectural glazing features in modern residential design. A pane of glass rises vertically before continuing across the roof, creating an uninterrupted transition between wall and ceiling that floods interiors with natural light.

While the framing system creates the overall structure, the glass specification is critical to the performance, safety and longevity of the installation.

At Crystal Units, we manufacture bespoke insulated glass units for up and over glazing systems, supporting glazing companies, window manufacturers and installers with technically engineered glass that is designed specifically for each project.

Whether supplying a slim glazed strip running from wall to roof or large-format structural glazing units, our team provides the technical support and manufacturing expertise needed to deliver premium architectural glazing.

Complex glazing projects require far more than simply manufacturing an insulated glass unit.

Our technical team works with customers throughout the specification process, helping ensure every glazing unit is designed correctly before manufacture.

We support customers with:

• Technical specification advice
• In-house glass calculations
• Wind load calculations
• Barrier load assessments
• Glass specification to suit structural requirements
• Silicone-sealed insulated glass units for enhanced durability
• Black ceramic borders for a premium concealed finish
• Polished edges where required
• Large-format insulated glass units
• Solar control coated glass
• The UK’s only licensed facility for painting Guardian SunGuard and ClimaGuard coated glass
• Dow Corning Quality Bond licensedTM structural glazing manufacturing

This combination of technical support and specialist manufacturing helps installers reduce project risk while delivering outstanding finished results.

Every project has different performance requirements.

Crystal Units manufactures insulated glass units using a wide range of specialist glass products, including:

• Toughened safety glass
• Laminated safety glass
• Heat soak tested toughened safety glass
• Solar control coated glass
• Low emissivity coated glass
• Acoustic glass
• Large-format glazing
• Decorative ceramic borders
• Bespoke coatings and finishes

For projects requiring enhanced performance, our glazing can also incorporate:

C.U.in

Our suspended film insulating glass technology delivers ultra-low U-values while reducing overall unit weight, making it ideal for demanding architectural glazing applications.

NUCLR Heated Glass

NUCLR heated glass can provide condensation control, add heat to the space, improved comfort near large glazed areas and snow and ice reduction where required.

Up and over glazing places significant demands on the insulated glass unit.

Roof glazing requires careful consideration of:

• Wind loading
• Barrier loading
• Structural performance
• Safety requirements
• Thermal movement
• Water run off
• Long-term durability

Our technical team works alongside glazing companies and window manufacturers to ensure every insulated glass unit is manufactured to suit the specific structural and performance requirements of the project.

The visual finish is just as important as the glass performance.

Crystal Units offers a range of manufacturing options to help deliver a clean architectural appearance, including:

• Black ceramic border printing
• Precision polished edges
• Silicone structural edge seals
• Solar control coatings
• Large uninterrupted glass panels
• Specialist painted solar control glass

These finishing options help create the minimalist appearance expected from premium architectural glazing.
