Double Glazing Trade Suppliers Southampton

Connaught Windows offers double glazed windows and doors to our Southampton trade customers. Double glazing provides enhanced benefits compared to old single glazed windows, doors, and conservatories such as better energy efficiency, weather resistance, durability, and more!

Features & Benefits

Thermally Efficiency

Our double glazing is highly thermally efficient, and can help improve a Southampton property’s heat retention. A new set of double glazed windows could help your customers save money in the long run as it becomes easier to keep their home warm without the need for as much heating.

Sound Insulation

Double glazed panes of glass help to muffle sound, much in the same way that it helps keep heat in. There are multiple benefits to this, including allowing the homeowner to be louder within their own property without causing neighbourhood disturbances, and helping the homeowner avoid being disturbed from outside noises.

Increased Security

The added thickness and materials that double glazing provided makes the windows and doors harder to shatter as well as heavier than a single glazed unit. This leads to a more secure and robust product that can withstand harsh weather conditions and unwanted intrusions.

Double Glazed Windows & Doors

A key benefit to becoming a Connaught Windows trade customer is our vast collection of double glazed products. We have a range of different PVCu and aluminium profiles to match modern or classic style Southampton properties, helping our trade customers offer an excellent selection to their Southampton customers. From bifolds to sash windows, or even classic casements, you can get a full supply under one roof, and we even offer a variety of decorative glazing!
