Our double glazed slide and turn doors offer slim non-thermal aluminium interlocking frames with slender aluminium edges. The double glazing not only helps add additional thermal support - it also improves the sound insulation. An ideal product for all year round, keeping away the worst of the winter weather when used externally. During the summer months it can be opened completely to make the most of these precious times. This style of door has a single track and offers a single panel opening with then the ability to slide and stack all the remaining panels open. With slide and turn systems the panels are easily slid open around corners if required, with all panels stacking to one or both sides.
