REINFORCING STRUCTURE FOR A WINDOW FRAME SYSTEM

摘要

A method of reinforcing and sealing a composite frame is provided. The method includes receiving material for processing, the material having surfaces defining at least one continuous channel therein; cutting the received material to a desired length; forming at least one notch in the material at certain angles thereby defining a pair of notch surfaces; placing reinforcing structures and sealing measures within at least a portion of the channel; and folding the material at the notch so that the notch surfaces are in abutting relation and moving the ends to be in abutting relating to define a closed frame. The reinforcing and sealing structure increases the structural integrity of the frame and provides a seal tight exterior as well as an aesthetically pleasing finished product.
