Secondary Glazing

Secondary Glazing Units are perfect for Listed buildings and conservation areas! and are commonly recommended by English Heritage and Listed Property Owners Club.

They are a cost-effective method of insulating and sound proofing your home. On average you can save around 10% on your heating bills and is an ideal solution if you are unable to upgrade or replace your existing windows.

Secondary glazing is an excellent way to improve the comfort, energy efficiency and acoustic performance of your home while retaining your original timber windows. Installed discreetly on the inside of your existing sash or casement windows, secondary glazing creates an additional insulating barrier that helps reduce heat loss, minimise draughts and significantly lower external noise levels. Because the original windows remain untouched, it is often an ideal solution for listed buildings, conservation areas and period properties where preserving character is important. Available in a range of styles to suit different window types, secondary glazing provides a practical, cost-effective upgrade that can make your home warmer, quieter and more comfortable throughout the year without altering its external appearance.

With a variety of secondary glazing units to suit all windows styles including the following;

For Sash windows we can supply and fit either a tilt back vertical slider unit which slides like a sash window but also tilts into the room for the ease of cleaning, or if you prefer a more affordable option, we also offer an unbalanced vertical slider which opens like a sash window but minus the balances, this unit has spring catches to lock it in position.

With Casement windows depending on the style we can supply and fit either a Hinged unit or Horizontal Sliders which slide smoothly for ease of ventilation and are available with two to five panels. The units can be easily removed for cleaning and can also be fitted with an integrated fly-screen for all year round use to keep insects out of the kitchen.

The units can be fitted with standard 4mm float glass, 4mm Obscured or Textured glass for Privacy, 6mm Toughened Glass, Safety or 6.8mm Acoustic glass. Prices will depend on glass chosen.
