SUNtec™ 3T

The SUNtec™ 3T Triple. Thin. Thermal range from Olympic Glass delivers outstanding thermal efficiency, enhanced security and long-term performance for modern building projects.

Low U-values help reduce heat loss and lower energy bills, while improved insulation creates a more comfortable, quieter environment inside. With overall unit thicknesses from 28mm, depending on glass sizes, the range brings triple glazed performance to a slim unit.

The range comes in four options: 0.9, 0.8 and 0.5 U-value units for increasing levels of thermal performance, plus a Secure unit with a 4.8mm laminated inner pane for added protection. Manufactured with sustainability at the heart of everything we do, SUNtec™ 3T is the smart choice for high performance glass.

Thermal Efficiency

Low U-values for improved energy performance and comfort.

Enhanced Security

Laminated options for greater protection and peace of mind.

Sustainable Choice

Manufactured with sustainability at the heart of everything we do.

0.9 U-Value

A high-performance thin triple-glazed unit delivering a centre-pane U-value of 0.9 W/m²K. Designed to reduce heat transfer through the glazing, it helps retain warmth during colder months while maintaining the benefits of a slim, lightweight triple-glazed design.

0.8 U-Value

Take thermal performance a step further with a centre-pane U-value of 0.8 W/m²K. Offering improved insulation compared with the 0.9 option, it reduces heat transfer through the glass, helping to minimise heat loss and support greater energy efficiency without compromising the slim glazing profile.

0.5 U-Value

Designed for projects where exceptional thermal performance is essential, this advanced glazing achieves a centre-pane U-value of 0.5 W/m²K. Its superior insulating performance helps minimise heat transfer through the glass, making it an excellent choice for energy-efficient buildings and demanding thermal specifications.

Secure

Add an extra layer of protection with a 4.8 mm laminated inner pane. Designed to help hold glass fragments together if the glass breaks, laminated glazing provides additional safety and can enhance resistance to intrusion. Depending on the glass configuration, it can also improve acoustic insulation, combining practical protection with the thermal benefits of thin triple glazing.

Energy Efficient

Lower U-values help reduce heat loss and lower energy bills.

Comfort & Quiet

Improved insulation for a more comfortable, quieter environment.

Secure by Design

Laminated options provide enhanced safety and security.

Sustainable Solution

Supporting greener buildings with long-lasting, high performance glass.
