Secondary Double-Glazing for Period Listed Properties

If you’re looking to improve the thermal insulation of your period listed property; you might be a little limited as to what you can do. Listed properties are subject to specific building regulations, and you may need planning permission in order to install new windows on your property. In rare instances, building regulations will prohibit you from replacing the original window units.

Therefore you will need to find a way of improving the thermal insulation of your original window units without replacing them. That’s where secondary double-glazing comes in. These are additional glazed panels that fit around the original units, providing you with an extra layer of insulation.

Installing Secondary Double-Glazing for Period Properties

Secondary double glazing units are perfect for period listed properties, as they provide a quick, clean, and non-disruptive installation. The installation of secondary double glazing is not generally subject to both planning permission and building regulations; this means they are an ideal way of adding extra insulation to your home.

Our aluminium secondary double glazing units are all strong, reliable, long-lasting, low maintenance, and very discreet. Don’t forget, having these units installed will help to save money on your energy bills, as well as improve energy performance certificates. You’ll also have the added benefit of additional sound insulation when having secondary double glazing installed.
