Weatherstrip
A piece of material used on windows or doors to reduce leaks and prevent rain and wind from entering the structure.
Weathertight
Hermetically-sealed to prevent entry of water and air into the structure.
Weathering
The action of water on exposed materials - glass.
Wheel Engraving
A process by which the glass surface is decorated using grinding wheels.
Wind Pressure
The amount of pressure produced by wind velocity on the glazing surface.
Warm edge spacers
Insulating spacers used to seal Insulating glass. Since they do not contain aluminium, they are less conductive, thereby improving the U-value of the window, and reducing condensation.
Waterjet cutting technology
This system consists of high pressure (60.000 psi) water, mixed with abrasives, that passes through a gauge orifice at three times the speed of sound. Such pressure produces a pure working power able to cut any shape of glass or other materials
Wind load
The pressure acting on an external surface of a building caused by the direct action of the wind.
Wired glass
A product in which a wire mesh has been inserted during production. It has an impact resistance similar to that of normal glass, but in case of breakage, the mesh retains the pieces of glass.
