Double Hung Windows

The 4800 Double Hung features a patented "candy cane" operating jamb stop which seals the ends of the interlock rail and the face of the lower sash with perfection! No other double hung has it. The 4800 is quite possibly the tightest double hung of any double hung made today!

4800 Series Double Hung Window

Gerkin traditionally seeks to build in long-term performance with all windows and doors. That’s why they use multi-chambered fusion-welded vinyl along with multiple areas of internal aluminum reinforcements. The 4800 works best when the weather conditions are at their worst. All sash members have full perimeter internal aluminum reinforcements. This extra structure restricts sash deflection under strong wind loads and allows all three weather seals to stay firmly connected for unsurpassed performance!
