In-line sliding doors (also known as patio doors) are great for giving a sense of light and space to a home. Large glazed areas give a great view of the garden and with trouble-free rollers and tracks these doors are very easy to open. Designs are fully configurable, with up to four panes in a door, and optional side lights can easily give a full wall of glass. Today’s sliding doors are packed with security features like anti-lift blocks and multi-point locking. Toughened glass is supplied as standard and doors comply with all building regulations.
