Maybe not all,but I am noticing a disturbing trend of poor quality vinyl windows to the point I wonder if telling people to upgrade from single pane with storms is always a good idea.
I see busted seals at an alarming rate and lets face it buying a simple double hung to replace the warped ,not matched,tight,loose upper which falls when unlocked along with bad caulking makes me think.
I used to call casements “Florida windows” because they were made only for that climate and not Chicago’s with all the drafts but now the casements seem superior along with "Horizontal sliders) which have the fewest issues of all.
Some brands are better than others .
"Climate Guard seems to be the best that I have inspected with fewest issues.
how about the kind that have no metal retainer over the butel gaskets .
Facing south I sometimes find them melting and dripping in between the glass.
Anybody have an opinion on good and bad types or brands here ?
