Need a specialist for triple glazing in Old Knebworth? Our approved window installers will survey, quote and install to suit your property and budget.

Why use a professional?

  • ●Centre-pane Ug values as low as 0.5 W/m²K — close to insulated wall performance
  • ●Noticeably warmer internal glass surface, eliminating any cold-radiation effect
  • ●Essential for Passivhaus and ultra-low-energy new-build certification
  • ●Further reduction in street and garden noise on top of standard double glazing

Our approach

  • ●Two cavities filled with krypton gas for optimal U-value versus unit thickness
  • ●Three panes of 4mm glass with two 12mm warm-edge spacers totalling 44mm
  • ●Reinforced sash sections required to carry the additional 50% glass weight

All triple glazing projects are carried out by qualified window installers local to Old Knebworth, with full public liability cover and an insurance-backed guarantee.
