Types of Windows
Wood Double-Hung Windows
These go up and down and are weatherstrip with Qlon. This operating system was used in the late 1800s to late 1920s to early 1930s.
Rope Double-Hung Windows
This has a counterbalance, pulley, rope, and weight system. We use the Samson sash cord #8, which is what people originally used when installing this type of windows. The sash cord has a nylon filament in the center. It is also rated for 50 years. To balance out the weights and sashes, we use ½# and 1# lead weights. In addition, costs are inclusive of weatherstripping all wood double-hung windows.
Tape Balance Windows
There is a spring-loaded mechanism in this variant. Depending on the weight, it has 1 or 2 tapes per sash 4 ½, 6, 8, 10, 12, 14, and 16-pound sizes. This operating system was used in the 1930s and early 1940s.
Twin Sash Balances
This operating system runs from the 1940s up to the present day. It has a spring-loaded mechanism as well. There are 1 or 2 twin sash balances per window depending on the weight. The available pound sizes are 4 ½, 6, 8, 10, 12, 14, and 16.
Metal and Vinyl Single Hung
For this system, only the bottom part goes up. There will be some double-hung variants in the higher-end models.
