If you’re looking for a lot of ventilation, but don’t want to sacrifice performance, then take a look at the Comfort Series 4800 double hung. The 4800 is quite possibly the tightest double hung of any double hung made today!
Our double hung features a patented "candy cane" operating jamb stop that seals the ends of the interlock rail and the face of the lower sash with perfection! No other double hung has it. To complement this patented performance, we have included three or more weather seals in every area where the sash makes a connection with the frame, including the interlock. The 4800 fixed window complements the 4800 double hung as a stand-alone fixed window or can be used to mull fixed and specialty shapes in order to create custom configurations.
Gerkin traditionally seeks to build in long-term performance with all windows and doors. That’s why we 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!
Before a double hung window is to be considered a great window, it first must operate like a champ! That’s why we offer “assist-operated" block and tackle balances for easy opening and closing as well as easy tilt sashes for effortless cleaning.
The appearance of this window will impress all who see it! Its slimline beveled frame appearance and equal lite sash offers maximum open viewing.
Whether it’s a replacement window you need or a window for an addition or new home, the 4800 double hung offers all the bells and whistles along with the great performance that you would expect from Gerkin and then some!
