INSTALLATION INSTRUCTIONS for Vinyl Windows without Nailing Fin (JII011) Flush Fin Window A window without a nailing fin that has a face flange (trim only). Flush fin windows may also be known as flange, stucco flange or Florida flange windows. Head Expander A vinyl accessory used to cover the head of the window in some retrofit applications.
I have a couple contractors quoting to replace my builder grade windows and the two preferred guys I want to go with each say to install the new windows differently. They're going to use the same brand (Simonton 5500) but one contractor wants to install using a nailing flange and the other wants to use the 'replacement' installation method (no flange).
I know how both installations are done, but is there a difference in the long term efficiency, maintenance, etc. between the installation methods? When I asked the contractor who prefers using a nailing flange why he uses that method (I thought it was only used in new construction), he said the replacement method mainly relies solely on caulking to keep the windows insulated and that leads to more maintenance.
How To Install Vinyl Baseboard
I got a bid for $4600 from one company that uses no-flange windows. They have a 25-year guarantee on product and installation.
The next lowest bid was from a company which uses only windows with flanges. They told me the 'glue-and-screw' windows will eventually leak (because the caulk will eventually fail), while their windows, with flanges, won't. However, the guarantee is similar. Their bid was for almost $7000.
I don't want to spend the extra $2400 if I don't have to, but I don't want to sentence myself to a future of fixing leaky windows by going with the cheap option now.
Are 'glue-and-screw' flangeless windows a bad idea?
One other consideration: I want to remove the vinyl siding and return the house to its cedar shake shell. I realize the window detailing was probably ruined when the vinyl went on -- but do either of these replacement options have a bearing on that?
Thanks in advance for your help!
