In actual fact the steel doors either one cs or premium will hold a seal better than the fiberglass ones when under wind pressure.
Pella vs therma tru fiberglass doors.
Fiberglass is often considered one of the most energy efficient choices available but if you prefer the appearance of wood pella s vividgrain stain process provides a wood appearance on the fiberglass panel.
What s more therma tru doors are backed by full system.
I replaced the steel entry door with a pella fiberglass door.
Pella therma tru andersen doors etc.
The pella door showed signs of rot and delamination within 18 months of installation it s a wood frame with fg skins like therma tru i replaced the pella with a plastpro which is holding up beautifully for the past two years.
I can let you know when i have it installed.
The quality of the perimeter seal is the same from the down and dirty construction series steel doors up to the classic craft fiberglass beauties.
I had read about two years ago that therma tru has excellent quality in consumers report.
I just purchased a therma tru door but i have not had it installed yet.
While therma tru s fiberglass door systems have the rich look of wood they won t rot crack or split like wood doors or dent rust or corrode like steel doors.
I liked the look better than the pella.
I have a friend who has a pella and she loves her door.
Provia is generally a little more expensive than therma tru especially in the builder grade or as therma tru calls it heart of the market fiberglass.
