Binding in The Frame
All glass expands and contracts with changes in temperature and deflects due to wind. This means that almost all modern glass is set on resilient blocks at the bottom and with space for expansion at the sides and top. The gaskets holding the glass in the frame are also usually resilient to cushion the glass against wind buffeting. If no space is provided at the perimeter of the unit, the glass will bind against the frame causing internal stresses to develop in the glass which can exceed the strength of glass resulting in breakage.
