12 May How to choose between a lift and slide door and a sliding door
It all comes down to size and weight with this glazing query.
Modern walls of glass that allow us to engage with the outside whilst remaining warm and dry inside are incredibly on trend. Many are moving away from the many leaves of a bi-folding door and exploring the potential of a slide or lift and slide alternative – thus giving them much large panes of glass and an uninterrupted view.
This in itself presents its own issues. A compromise must be struck between size and weight of the glass pane, being easy to open and shut (which requires as little friction as possible between the frame and the pane) and performance – being able to keep wind and rain out requires a good seal between the frame and the moving pane.
Most doors of this type are opened by pushing/sliding a pane of glass in front or behind another, and it is the type of mechanism that provides the ratio between size, opening and performance.
A traditional slide door is usually on rollers of some description, within the frame and you push against insulating brushes or gaskets and with a door of small to moderate size this works well enough in terms of performance and ease of opening, however to achieve the designer glass wall look much larger piece of glass need to be used. It is possible with a lift and slide door to go up to 3 meters in height, double or triple glazed and up to 400kg in weight and still be able to open the door with 2 fingers.
How you might ask? A Harry Potter style swish of a wand and mutterings of “Wingardium Leviosa”? no much easier to turn a slightly longer handle 180 degrees, which in turn lifts the heavy glass out of the frame by just a few millimetres. This significantly reduces the friction and allows for a smooth and easy opening.
