Window Leaks and Damage
Web site readers are asked to remember that this window company received a 22 page, picture rich power point presentation that included the bulk of these pictures. The window manufacturer chose first not to respond to the presentation, never did acknowledge receipt of the presentation and then accused all else but their windows as the cause for the leaks and damages.
The window company's only modification to their position is that they no longer claim the windows were improperly installed. A second curiosity was the third window inspection, the one contracted by this window manufacturer, focused entirely on the panel windows and did not test a single casement window. We view this as one more indication this window manufacturer is aware of their panel window design flaw is centered on the large, double pane windows.
Pictured below is just a sampling of the rain water penetration damage done to the interior window trim and surrounding hardwood trim.
This (picture below) is the bottom window sill of a casement window that adjoins one of the large panel windows that bellows in the wind allowing water to enter and damage the panel and adjoining casement window trim, walls and floor.

The interior wall sheet rock also suffered water damage in the form of swelling, lifted joints, cracking and black mold. All home sheet rock damage is under this window company's panel window locations alone, no where else in the entire house.
This picture below is the wall space below a lower level window and the floor.

The hardwood interior trim will be pulled, sheet rock removed, black mold cleaned, trim refinished & replaced, at cost to the homeowner. This is the homeowner's retirement home, a middle class family, his only affordable means to repair this damage caused by this window design is to do the work himself.
What we are showing here as best we can is the volume of water infiltration through the one specific window design as evident by the water puddle on the floor during a regular rainfall.
The red double arrow shows the water puddle edge and travels back under the base board wood trim.
The black arrow titled "water puddle" shows the outline of the forward edge of the puddle.
The homeowner response to any rainfall has been to line the panel window bottom sills with bath towels and more on the floor. The towels are placed below the panel windows on the house side the wind may drive the rain. The combined effects of rainfall volume and wind force on the bellowing panel windows determines which windows will pass the most water.
Remember to note the Eagle brand windows on this same house do not show any water infiltration during the same rainfall.
