Extension bifold doors or sliding doors?
Choose the right glazing for your extension
Both extension bifold doors and extension sliding doors can open up your new living space, bring in more natural light and create a stronger connection with the garden. The right choice depends on how wide you want the opening to be, the views you want to preserve and how you plan to use the space day to day.
Rex can help you compare the different layouts, frame styles and glazing options so the doors work with the design of your extension as well as the way you live.
