the rough opening 200 in effect the entire channel 500 would remain but would stay filled with the wicking object 450 the wicking object 450 would not impede the flow of moisture to the sill 230 but would help wick the moisture to the sill 230 the wicking object 450 could be made of a material that conveys the moisture via capillary action alternatively the wicking object 450 could be formed of any material that would allow the flow of water while impeding the flow of foam 320 for instance the wicking object 450 could be formed of a porous fibrous material that does not use capillary action but does allow water flow one example of such a material is the home slicker u00ae product sold by benjamin obdyke incorporated horsham pa alternatively traditional fiberglass insulation can be used since water is not absorbed by the glass fibers found in fiberglass insulation water that enters channel 500 would flow through the fiberglass fibers 450 down to the sill 230 fig1 shows a sixth embodiment of the present invention in which a wicking strip 460 is attached directly to the window frame 120 in the preferred embodiment the wicking strip 460 abuts against both the.
