Smooth Movement Sashes are one of the leading Secondary Glazing companies in Essex.

If you have a listed property, wish to retain the original sashes and glass in your windows, or double glazing is not suitable then secondary glazing could be a cost effective option for you to consider.

Secondary glazing is a fully independent window system installed to the room side of existing windows. We offer secondary glazing to suit every application, including open-able, removable and fixed units. The fixed units are designed to be removed in warmer months when the thermal benefits are not required.

The main benefits of secondary glazing are:

  • Retaining your original windows and glass
  • Drastically improving window efficiency
  • Reducing heating costs
  • Contributing to the elimination of outside noise

Secondary glazing units can be provided with a variety of glazing options to suit your individual requirements.

We are based in Essex but also cover London and the home counties.

“I would recommend Smooth Movement Sashes to anybody looking for secondary glazing. The process has been fantastic and has definitely made a huge difference to our house. The difference in the sound level is amazing and the house is so much quieter inside.”
Steve Allen, Colchester, Essex

“We can’t recommend this secondary glazing enough. Our lounge is warmer and the condensation is gone. I can actually see my garden now.”
Barry Young, Billericay, Essex
