Secondary glazing involves fitting a discreet internal window in addition to your existing window. It’s a cost effective and efficient way to insulate and sound-proof your windows, and perfect for use in Listed Buildings and conservation areas.
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.
Recommended by English Heritage, the Listed Property Owners Club and the Energy Saving Trust, the benefits of secondary glazing include:
- Noise reduction
- Minimise drafts
- An additional security barrier
- Condensation control
- Reduced carbon footprint
- Available Options
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 to form arched units.
When sound-proofing is paramount, we recommend using a different glass thickness in your secondary glazing than that of your existing windows. Special acoustic glass provides maximum noise reduction.
For maximum thermal performance we specify “low E” glass, which has a special heat reflecting coating to help keep heat within the room. 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.
