The Gerkin Comfort Series single hung is a new generation window for Gerkin! After a decade of proven performance with our single hung, we found a way to make it even better! The single hung window is highlighted by the use of a stylish 2 1/2" beveled frame design, fusion welded sash and frame and triple weather seals. We have designed this window to perform at a very high level through the use of multiple vinyl chambers, internal aluminum reinforcements, heavy-duty block and tackle balances as well as warm edge technology glass!
