Secondary Glazing

Secondary glazing is a great alternative to refitting your entire home with double glazed windows. Used widely in homes, offices and many other properties, secondary glazing is a recommended solution for a swift and easy installation option.

Our secondary glazing service is extremely efficient: we simply install a second pane of glass over an existing window installation. This grants you the same benefits that double glazing would, but at a fraction of the cost. Furthermore, the build quality of your existing window installation is never compromised and we guarantee all of our work and materials to give you extra peace of mind.

Benefits of Secondary Glazing

Recommended by English Heritage, the Listed Property Owners Club and the Energy Saving Trust, the benefits of secondary glazing include:
Up to 80% noise reduction

  • Minimise drafts, reduce heat loss by up to 65%
  • An additional security barrier
  • Condensation control
  • Reduced carbon footprint

What is Secondary Glazing?

Secondary glazing involves fitting a discreet internal window in addition to your existing, single, double and triple glazed window. It’s a cost effective and efficient way to insulate and soundproof your windows, and preferred for the use within Listed Buildings and conservation areas.

Sound Insulation

When soundproofing is paramount, we recommend using a different glass thickness in your secondary glazing than that of your existing windows, this decrease sound reverberation. An air cavity of 150mm to 200mm and special acoustic glass provides maximum noise reduction often reducing noise levels by up to 80% (54dB).

Thermal Insulation

For maximum thermal performance we specify “low E” glass, which has a special heat reflecting coating to help keep heat within the room. A recommended air cavity of up to 80mm is advised. We’ve helped thousands of homeowners and commercial clients over the past 20 years. We’d like to think that we can help you too.

About Our Secondary Glazing

All aluminium frames are painted white as standard, though you can select from over 200 RAL colour options – to mirror the look and feel of your home.

Windows are made to measure, with options to accommodate nearly all window styles. Horizontal sliders are the most popular choice, though we can supply and install vertical sliders, hinged units, fixed and lift-out windows. Our secondary glazing can even be curved in house to form arched units.

Face or Reveal Fix

Made from durable aluminium, frames are slim, unobtrusive, and require little maintenance. They’re also easy to install by fixing to your existing window (“face-fixed”) or into the window reveal (“reveal-fixed”).

With a reveal-fix, having a 100mm-200mm air gap between secondary glazing and your existing windows will provide optimum performance – preventing heat and sound from passing through.
