Secondary Glazing

from EcoChoice Double Glazing, Kent

Adding a slim-line, secondary window in addition to your existing windows, is a cost effective and efficient method of insulation and sound proofing. The Energy Saving Trust states that it is an “ideal solution if you are unable to fit double glazing” and, by having secondary glazing installed, you could save around 10% on your heating bills.

Secondary glazing is:

  • made from strong, lightweight aluminium
  • can be very slim and discreet
  • a reversible change
  • an ideal solution for sound-proofing
  • perfect for use in listed buildings and conservation areas
  • recommended by English Heritage and the Listed Property Owners Club
Vertical sliding secondary glazing

Vertical Sliding Secondary Glazing

Ideal for providing thermal insulation and sound proofing for traditional wooden box sash windows, or any other windows that have horizontal bars.

Panels move the same way as vertical sliding sash windows and provide easy access to the existing window.

Hinged secondary glazing

Hinged Secondary Glazing

Hinged secondary glazing is ideal for hard to treat areas such as bay windows and other specialist applications.

It lends itself particularly well to large glass areas where quick and easy regular access is required. i.e. for maintenance, ventilation or cleaning.



Flyscreens are made to measure from durable Aluminium frames with a fine non-combustible and non-corrodible fibre glass yarn mesh which excludes insects, but is fully translucent and allows full ventilation.

You can easily replace existing mesh, in case of damage.

Horizontal sliding secondary glazing

Horizontal Sliding Secondary Glazing

Perfect for sound and thermal insulation for casement windows, hinged windows, or any window that has vertical bars.

Panels slide within the frame allowing easy access to the existing windows and providing ventilation without interfering with curtains or blinds.

Lift out secondary glazing

Lift Out Secondary Glazing

This system can be used to treat large areas of clear glass while avoiding being visible from outside.

The large panels can be lifted out of the frame for cleaning or to provide ventilation.

Combination secondary glazing

Combination Units

Combination secondary glazing is most suited for copying an existing combination window.

We can combine Lift Out and Hinged units in a variety of different configurations.
