Manufactured 
with quality &
care in mind.

By incorporating three panes of glass and two insulating cavities, triple glazing, when using the correct glass makeup, helps reduce heat loss and improve overall window performance.

At Regency Glass, we manufacture high-performance triple-glazed insulating glass units (TGUs) tailored to meet a wide range of residential and commercial glazing requirements.

Tailored

requirements.

Available options include:

  • Glass thickness variations for strength, acoustics, and specification requirements
  • Performance coatings to improve thermal efficiency and solar control
  • Safety glass options, including toughened and laminated glass
  • Spacer bar systems, including advanced warm edge technology
  • Patterned and decorative glass for privacy and design applications
  • Gas-filled cavities, including argon gas for enhanced insulation

For optimal thermal performance, triple-glazed units typically incorporate two panes of low-emissivity (Low-E) glass.

A common high-performance specification includes:

  • 4mm clear glass
  • 4mm Low-E glass
  • 4mm Low-E glass

Glass manufacturers highly recommend that the middle pane be toughened to reduce the risk of the glass shattering under thermal stress. This helps to ensure long-term durability, reliability and safety.

Please note, Regency Glass will not produce standard TGUʼs without toughening the middle pane.

Standard Triple Glazing Sizes & Weight

Standard triple-glazed units are typically manufactured with an overall thickness ranging from 36mm to 44mm, depending onthe specification and cavity configuration.

Due to the additional pane of glass and larger construction, triple-glazed units can weigh approximately 30kg per square metre,making correct handling and suitable frame compatibility important considerations during installation.

Regency Triple® featuring Corning® Enlighten™ Glass is only 21kg per m2 and offers TGU performance at the same weight andthickness as a DGU. Click here for more information.
