Window Glazing problems
These two window glazing photographs, one from the inside (above) and one from the outside (below) of the building demonstrate graphically why our glazing process is so important to the longevity of wood windows and doors. Notice how the owners of the building, that has dozens of pieces of glass, has paid someone to come and carefully mask and caulk the glass on the inside of the building to prevent water ingress between the glass and the sash. There is no reason for this to be done if the windows have been glazed properly.
The real issues here are not just the aesthetics and the additional cost. All that has been done by adding the caulking is to prevent the water from evaporating from the glazing pocket. This water should not find it’s way into the glazing pocket in a properly glazed window. This will create rot in the glazing pocket, especially if it hasn’t been pre-finished and eventually cause seal failure and the need to replace the sash and the glass.
By glazing improperly the manufacturer has saved a relatively small amount of time but has cost the owners of the building tens of thousand of dollars in damage.
