About Triple Glazing

Triple glazed units feature three glass panes separated by two insulating cavities, typically configured as 4mm-16mm-4mm-16mm-4mm for optimal thermal performance. Each sealed unit incorporates advanced Low-E coating on internal surfaces to reflect heat back into the room whilst maximising natural light transmission.

Filled with argon gas or premium krypton gas between warm edge spacer bars, our triple glazing achieves exceptional U-values from 0.5 W/m²K - significantly outperforming standard double glazing. All units comply with BS EN 1279 standards and deliver superior energy efficient performance, reducing heating costs whilst eliminating cold spots.

Every triple glazed unit is made to measure at our UK facility with precision cutting to your exact specifications. We guarantee quality manufacturing with nationwide delivery, ensuring perfect fit for your replacement glazing requirements.

Frequently Asked Questions

  • What U-value can I expect from triple glazed units?
    Our triple glazed units achieve U-values from 0.5 W/m²K with argon gas fill and warm edge spacers. Premium krypton gas options can deliver even lower U-values for maximum thermal efficiency.
  • What's the typical thickness of a triple glazed sealed unit?
    Standard triple glazed units measure 44mm overall thickness (4-16-4-16-4 configuration). We can manufacture alternative thicknesses from 32mm to 54mm depending on your frame requirements and performance needs.
  • How does triple glazing compare to double glazing for noise reduction?
    Triple glazing provides superior acoustic performance, typically achieving 35-40dB noise reduction compared to 28-32dB for standard double glazing, making it ideal for busy roads or urban environments.
  • Do you deliver triple glazed units nationwide?
    Yes, we deliver made to measure triple glazed units throughout the UK. Orders are carefully packaged and shipped direct from our manufacturing facility with tracking provided for all deliveries.
