Replacement Windows O'Fallon

Replacement windows (also known as retrofit windows) have been developed as a labor and cost-cutting alternative compared to new construction style windows that require the existing window frames to be completely removed.
There are two main varieties of replacement windows:
Flush fin (also called Z-bar) replacement windows
Typically used in markets with aluminum windows in stucco home exteriors. This method leaves the original aluminum window frame intact and provides very little opportunity for the stucco siding to be damaged.
Block frame or insert replacement windows
Typically found in markets where wood windows are in place, and the exterior is siding or brick. In most parts of the country, the block frame window is simply a new construction window frame with the nail fin removed.
