For many Listed building owners, or people who live in conservation areas, warmth and noise reduction can be a real issue. You can rest assured that Britelite’s secondary glazing will significantly improve both aspects.

Our Secondary Glazing is strong, reliable and long-lasting. By installing Secondary glazing you are creating a insulating layer of air which will retain the heat. Combine this with low-E glass and you could reduce heat loss by as much as 65%.

Secondary glazing is extremely difficult to open from the outside and provides an additional physical barrier against forced entry. Our frames are made from tough aluminium and securely fixed to resist forcing.

With our slim, discreet aluminium profile incorporating both horizontal and vertical sliding sashes our range of secondary glazed windows offer minimal sight lines and easy access to the primary glazing for cleaning.

  • From noisy roads to rattling railway lines, our internal windows can reduce noise levels by up to 80% (50db)
  • Our secondary glazing eliminates draughts, and can reduce heat loss by up to 65%
  • Horizontal sliding windows are versatile and provide easy access to the outer windows
  • Vertical sliding units are ideal for treating traditional sash windows

So whether its for the added security, condensation control, noise reduction or energy efficiency, Britelite secondary glazing makes it the ideal solution for home owners.
