Invite The Outside In with the SafeGuard Bi-Fold Door Our SafeGuard Bi-Fold doors have been designed and extruded in Great Britain and are manufactured to exacting standards in our own dedicated manufacturing facility. This attractively crafted door is made from premium grade Aluminumwhich is expertly finished to the highest standards. A Bi-Fold door can enhance any home, from a period property to a modern design and build project. Its guaranteed to change the way you view the outside world, all year round. OPENINGUP THE OUTSIDEWORLD With the doors fully opened the boundary between inside and out becomes blurred and the true benefit of the door is experienced especially on those warm summer evenings. To ensure maximum weathering performance we recommend an outward opening configuration using our standard weathered threshold. Although this requires a small step over, the threshold can easily be set down to enable a more seamless link. Our Bi-Fold doors can also be used as an internal room divider using the specially designed level access bottom track. This non weathered tracking is ideal for use between rooms and conservatories. Please seek advice from your installer as to the most suitable threshold for your location.
