Homeowners could paint the house any colour they want, add a storm door and probably put up a fence.
Using wood thicker than one inch allows the storm door frame to accommodate glass panels.
They can also be moulded in such a way as to realistically mimic wood grain to provide the appearance of a wooden storm door.
Whereas interior closers typically use hydraulics, storm door closers are more typically pneumatic, using air and springs to close the door.
Fibreglass storm door frames are extremely strong, but the material is more expensive.
As the storm door frame gets thicker, the door frame becomes more rigid.
