At Emerald Windows, we cover the South West of England and provide award-winning service to all types of properties from Swindon to Reading and Bristol. Not only do we have a huge range of products to install, but we also have a double-glazing showroom based in Swindon too, ideal for those looking to try before they buy. We have an incredible range of windows to choose from, including the popular casement windows and classic sliding sash windows.
Our door range is similarly extensive, featuring traditional back door options like French doors along with contemporary choices such as bifold doors. Not only do we have a range of styles, but our doors are also available in a number of materials, from uPVC and aluminium to composite and even timber.
If you are after a bit of extra space for your Swindon home, you could do worse than consider one of our glazed extensions. Whether it be a classic conservatory or an effective orangery, there is an abundance of choices to be made. If you already have an extension in place but it is in need of a bit of an upgrade, we have replacement roof options to choose from, be it a glass conservatory roof or a tiled conservatory roof.
