We have had three salesmen come out for estimates, and they have all contradicted each other, not to mention try to pressure us into buying right away.
Question about sealing: One salesman said that they use Anlin windows and seal the windows with foam insulation. Another said that foam insulation would break down and eventually harm the vinyl, that this type of insulation would cause the manufacturer to revoke its warranty, and that caulking was a better way to go. Can someone please clarify this dilemna?
Question about the vinyl: One salesman said that virgin vinyl is the best way to go because it is stronger and prevents yellowing. Another said that virgin vinyl will yellow with time; he said that additives should be added to vinyl to strengthen it and prevent yellowing. Which is correct?
Question about warranty: One salesman tried to give us the incentive to purchase by telling us that we could piggyback with a commercial order he was placing and this would "save" us $3,000. Is this possible, or is the salesman just using another tactic? If piggybacking does occur, would the manufacturer not give us the warranty because the windows were not sold directly to a resident as opposed to a commercial business?
I really know nothing about windows, so any answers and additional information would be appreciated. Who are good manufacturers of vinyl windows, what makes up a good quality vinyl window, what is the best installation that prevents leakages/condensation, and what do I need to watch out for? Thanks in advance.
