Aluminium Secondary Glazing / Secondary Double Glazing
Secondary Glazing involves adding an extra slim-line window in addition
to your existing windows. Secondary glazing is designed to keep the
heat in and the noise out. You could also save around 10% on your
heating bills. Our Secondary Glazing is made from strong lightweight
aluminium so that the frames can be made very slim and discreet.
Secondary Glazing is perfect for use in Listed Buildings and
conservation areas. Adding secondary glazing is a cost effective and
reversible change that is recommended by English Heritage and the
Listed Property Owners Club. The Energy Saving Trust states that it is
'ideal solution if you are unable to fit double glazing'.
Secondary glazing should NOT easily be seen.
