Sliding windows are ideal where serveries to the outside are required and where no projections on to busy areas are wanted. Standard options include windows with a single sliding panel or two sliding panels meeting in the middle. A heavy duty Slidemaster version is available for demanding environments, and there is also the double slider where two panels slide past each other for greater flexibility. A double track option allows a timber shutter outside a glass panel for privacy and sunscreen purposes. Insect screens work well in conjunction with sliding windows so First sliders are a good option where insects are a problem and exterior mesh screens need to be fitted. Standard sliders can be built to panel widths of 800mm or more.
