Sliding windows are becoming increasingly popular because they are easy to operate and do not occupy space either on the interior or on the exterior. There are several series ranging from two-track to four-track. They are capable to being fabricated in heights ranging from a standard 4′ to as high as 10′.
The windows have very sophisticated facilities such as interlocking sections, grooves for weather strip, provisions for fixing locks and mosquito mesh on the outer track
Sections shown in video are of 18mm thick. Normally a builder provides 18mm thick Aluminum section. In this there are 3 tracks, 4 tracks and even a mosquito net can be fitted in one of the tracks. In aluminum section there are many sizes – 1 inch, 1.25 inch thickness, but then it becomes very heavy to move. The aluminum sections are Anodized or Powder Coated. In powder coating, due to sunlight the colour of the section gets dull and there are chances that the powder coating will come out. But in Anodised coating this thing doesn’t happen and the durability is long compared to powder coating.
In shops raw material and sections are available. It has to be cut according to the required size and then the window frames are sent for Anodized coating process and then fitted. There are few companies who give direct ready made aluminum sections but could be costlier.
