“Worrisome Windows”,
“Consumers are inundated with ads from regional window companies
that promise miracles. Maintenance free windows made of sturdy vinyl will not
rot, pit, rust or wear out. Such claims have helped make replacement windows a
$3 billion industry. Many of those windows will not last as long as the ones
they replaced. There are fewer than 10 major window manufacturers in the US but
more than 3000 companies making windows. If you and I wanted, we could do it in
our garage.”

“Worrisome Windows”,
“Vinyl softens at 165˚, A Temperature easily achievable in the space between
drapes and the windows on a sunny day. Vinyl expands and contracts 7 times more
than glass. This action can pop seals between frames and glass. Vinyl is simply
not suitable on its own as a window material. Says Mike Compleu of Anderson
Window Corp who has never made an all vinyl window.”
TREMCO Insulated Glass product
Newsletter, 1999,
“The typical house changes hands every 7 or 8 years. Some
manufacturers produce low quality windows and offer warranties too good to be
true. Because the homeowner is likely to move before the windows fail, you can
offer 20, 30, or 50 year warranties if they’re nontransferable.”
Canadian Centre for Energy
Technology, 1996 Study, Long Term Performance of Operating Windows,
“Air leakage in
vinyl windows increased 136%, significantly more than aluminum or wood.
Un-reinforced PVC profiles have a lack of rigidity and a high coefficient of
expansion. PVC profiles are subject to distortion.”
