High-Quality Double Glazed Sash Windows in London

Double glazed sash windows utilise the heat efficiency provided by double glazing. What is double glazing? It is a method of glazing your windows with double panes of glass to prevent heat loss. How does it work? It works by insulating your home against heat loss while also trapping the solar energy so your home is warmer without central heating.

The glass we use is treated to allow the sun’s light to enter the room, but it does not allow the resultant heat to escape. Additionally, the two panes of glass create a sealed unit which is filled with an insulating gas. This gap creates a blanket which does not allow heat loss through conduction or convection. In fact, our efficient installation also gives you a home that is free from cold draughts as well as rainwater seeping in.

Double Glazed Sash Window FAQ’s

Can Sash Windows be Double Glazed?

Modern sash windows can be double glazed, but if you are in a listed building or conservation area where you are not allowed to replace your sash windows with double glazing, you can look at applying secondary glazing to your London property.

What Colours Do Sash Windows Come in?

uPVC sash windows are available in both a selection of block colours such as Cream, Chartwell Green, Grey, Smooth White, Black, and White, and woodgrain foils such as Irish Oak, Cherrywood, and Golden Oak. Woodgrain coloured sash windows can easily replicate the traditional wood appearance.

How Can I Improve the Security of My Sash Windows?

All of our uPVC sash windows come equipped with state of the art key locking mechanisms and are more secure than the classic timber sash windows. Sash catches will secure the bottom sash, while sash stops allow the windows to be opened partially for ventilation with little room for unwanted visitors. We offer different glazing options which will also help.

How Can I Soundproof my Sash Windows?

Whilst we offer double glazing with our sash windows, the best way to soundproof your existing sash windows is with secondary glazing. We offer secondary glazing installations that will reduce the noise pollution of your home, helping to keep loud and unwanted noises from affecting your everyday life.
