3 Track Window

This system is used at places where space is a constraint. They can be used at places where the opening size of the window is big. These will have 3 tracks of sliding interlocked with each other. By using a Three track Sliding Window we can get 66 % opening. We can use glass from 4 mm to 20 mm in the sliding systems.Window tracks are the raceways in which the window slides up and down. Clean the window tracks first (because the windowsills will get dirty while you're working on the tracks). Vacuum the tracks, using a crevice tool to get into the narrow areas. You'll find dirt, dead bugs and dried leaves in there.
