French Doors can transform an existing doorway in your home into a grand entrance. The expanse of thermally efficient double glazed or triple glazed glass lets in floods of light and creates a real feeling of spaciousness, even when your French Doors are closed. French Doors provide easy access to your garden or patio area all year round, whilst allowing ventilation during hot summer periods. French Doors need not be solely limited to external use, as many homeowners utilize them to join an orangery or conservatory to their home. French Doors therefore can also create an impressive internal doorway.
