    What are bifold doors?

    Bi-fold doors are unique sliding doors that will transform your living space. With a concertina-style fold, the door panels neatly stack up on one side to completely open up your home. With up to eight door panels available, you can create a fully glazed wall if you wish, depending on the size of the space. By completely opening up the room, you can create an open-plan feel between your home and garden.

    These doors are perfect for summer, but you don’t have to worry about bi-fold doors letting you down during winter. Like all our doors, they still possess all the energy-efficient qualities that keep your home warm. Our door frames combined with our high-quality double glazing provide superior insulation. Security is taken care of too with multi-point locking and secure frames that will keep your home safe.
