What new glazing changes

Lower energy bills

The house holds its heat better, so the heating runs less.

Less noise

Noticeably quieter rooms, especially on a busy road. Acoustic glass helps further.

Better security

New frames with multi-point locks are much harder to force than old ones.

Misted, draughty or rattling windows

Condensation between the panes means the seal has failed. Sometimes we can replace just the glass. If the frames are tired too, new windows usually make more sense. We'll tell you which at the survey.

  • A-rated sealed units
  • Warm-edge spacers, which cut condensation round the edges
  • Toughened and obscure glass where needed
  • A FENSA certificate when the job is done

What A-rated means

A sealed unit is two (or three) panes of glass with argon gas between them and a thin coating that reflects heat back into the room. A-rated is the energy rating of the whole window, frame and glass together.

  • Two panes with an argon-filled cavity
  • Low-E coating reflects heat indoors
  • Warm-edge spacer reduces condensation
  • A-rated as standard. A+ available

Types of glass
