Gerkin single hung windows are often the favored choice for historical retrofit applications and as replacement windows where it is important that the new windows maintain the appearance of the old windows.

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!
