To ensure our sliding doors operate smoothly, an important step in installing our doors is to make sure the sill brace is used in conjunction with a 10mm packer, which is inserted between the subsill and sill brace. As each door panel can weigh up to 300kg, there is a great deal of downward force on each track. Without proper support, the track will bend in on itself, compressing the seal between the door panel and track. Even a millimetre or two of extra pressure can have a dramatic effect on the door’s ability to operate smoothly.
