Comfort Series Vinyl Windows and Patio Doors

These were introduced in 1993 to meet the new market needs in both new construction and replacement projects. These are high quality, maintenance free products that you can get at a fair price. The comfort series includes many different operating systems.

Single Hung

The 6100 series is highlighted by the use of a 2 ½” beveled frame design, fusion welded sash and frame, and triple weather seals. This window has multiple vinyl chambers, internal aluminum reinforcements, heavy-duty block and tackle balances, as well as a warm edge technology glass allowing it to perform at a high level. It also features a sloped sill design without weeps so there is excellent drainage and air infiltration but no weep holes to get plugged!

Double Hung

Double hung windows mean both the top and the bottom can slide open offering more ventilation. The 4800 series have a patented “candy cane” operating jamb stop that seals the ends of the interlock rail and and the face of the lower sash with perfection. No other double hung window offers this. It has 3 or more weather seals in every spot where the sash connects with the frame including the interlock. This window also has full perimeter internal aluminum reinforcements giving it extra support under strong conditions. The 4800 series also has the “assist-operated” block and tackle balances for easy opening and closing as well as easy tilt sashes for effortless cleaning.

Casement windows crank or push out unlike sliders. Gerkin comfort series open and closes with ease with the roto crank hardware with great leverage and power. The sashes do not stick and the handle folds away just like most standard casements. There are 21 champers of fusion welded vinyl created great strength, warmth, and long life span. With the 4300 series also come two heavy compression bulbs and a third secondary exterior seal that blocks the weather before the interior compression seals get a chance to work. The multi-point lock system and interlocking hinge side locks offer the tightest full perimeter seal.

Bays and Bows

Gerkin offers bay windows for large and small spaces. Gerkin comfort series bay windows come with natural oak or birch head and seat boards. Bay windows can have three windows in the opening with any of them opening and Gerkin can offer a customer appearance.




What’s the difference between a bay and a bow window? Bay extends out on straight angles where as a bow window is just how it sounds, it’s slightly bowed out in a rounded curve shape. Just like the bay windows, Gerkin Bow windows come with natural oak or birh head and seat boards. Bow windows give a unique look with a traditional appearance and smooth lines. Bow windows can have four or more windows in the opening and offer several different projections for a customer appearance.
