Windows : Slimline Units including Slimlite Glazing


Slimline Units including Slimlite glazing are a thin type of double glazing that has been recently developed and can be used in existing windows, unlike earlier forms of double glazing. Listed Building Consent would be required for such work and you should always check with your local Conservation Officer as whether it would be accepted or not, as generally there is a presumption against double glazing in historic buildings.
