About Clear Double Glazing

Clear double glazing utilises high-quality float glass in each sealed unit, delivering uncompromised transparency whilst maintaining excellent thermal insulation. Standard configurations include 4mm glass with 16mm or 20mm spacer bar combinations, providing effective thermal barriers without visual distortion.

Enhanced with Low-E coating and argon gas filling, our clear units achieve U-values from 1.2 W/m²K, significantly improving energy efficient performance over single glazing. All sealed units comply with BS EN 1279 standards, incorporating warm edge spacer technology to minimise thermal bridging and condensation risks.

Pane Relief manufactures every clear double glazed unit made to measure, ensuring perfect fit for your specific requirements. Each unit comes with comprehensive quality guarantees and reliable UK-wide delivery service.

Frequently Asked Questions

  • What glass thicknesses are available in clear double glazing?
    Standard configurations include 4mm glass with 12mm, 16mm, or 20mm cavities. We can manufacture units up to 28mm overall thickness with various glass combinations to meet specific requirements.
  • What U-value can I expect from clear double glazed units?
    Clear double glazing with Low-E coating and argon gas typically achieves U-values between 1.2-1.6 W/m²K, depending on glass thickness and spacer bar configuration specified.
  • How does clear glass compare to tinted or coated alternatives?
    Clear glass maximises natural light transmission at around 90%, making it ideal where brightness is priority. Tinted options reduce light but offer solar control benefits.
  • How do you ensure accurate sizing for replacement units?
    We provide detailed measuring guides and technical support. Simply provide opening dimensions minus 5mm on height and width for standard installations with appropriate glazing tolerance.
