What is Aluminium Track and why is it used in Upvc Sliding Windows & Doors?
This is a very common question that I receive from aspiring Upvc Window fabricators.
Aluminium Track is the small metal guide rail that you often see on the bottom rails or bottom of the Upvc frame profile of Upvc Sliding Windows and doors. It is made out of aluminium and hence the name aluminium track. Aluminium track is also known as aluminium guide rail in the market.
Now that you know what is a Aluminium Track and where it is used.
Its time to know when it is used during the fabrication of a Upvc Sliding Window or Door. In simpler terms, when is the right time to use a Aluminium Track in the making of a Upvc Sliding Window or Door and when can we skip the use of it.
First let us discuss about Upvc Sliding Windows.
If you are making a Upvc Sliding Window which is relatively small in size (window size less than 5′ x 4′) and you are also using glass of less than 6 mm in thickness. Then you can avoid the use of Aluminium Track in your Upvc Sliding Windows.
But if you are making a Upvc Sliding Window which has a glass thickness of more than 6 mm or if you are using Double Glazed Glass (D.G.U.), then it becomes mandatory to use a aluminium track in the bottom profile of your frame.
Now let us discuss about Upvc Sliding Door
Now read this carefully. Whenever you are making a Upvc Sliding Door irrespective of the thickness of the glass, it is mandatory to use a Aluminium Track in the bottom of the frame profile.
Skipping this would eventually lead to the damage of the bottom of the frame profile and you will be forced to replace the whole frame of the Upvc Sliding Door that you have made.
So please do not cut corners and skip the part of using a Aluminium Track during the fabrication of a Sliding Upvc Door.
One last thing, whenever you are using Aluminium Track or Aluminium Guide Rail in your Upvc Sliding Windows or Doors, always remember to use grooved rollers for the purpose. As flat type rollers will not be able to glide during the sliding of the window and door sash.
Check how a grooved roller looks like below:

Multi-point lock:
Multi-point locks are used in both Upvc casement windows and upvc casement doors. They are also known as espags. These are called multi-point locks as they get locks at more than one point, unlike single point locks.
Different combinations of handle can be used in espags for making Casement windows and doors.
3D and 2D Hinges:
3D and 2D hinges are generally used in casement doors to mount the door sash on the casement door frame. It can also be used in upvc casement windows, but friction stay is a more preferred option for Upvc casement windows.
During installation, it is recommended to use nylon capped galvanized fasteners for the fixing of the frames of the Upvc Windows and Doors.
Any gaps that remain around the wall and the Upvc Frame should be sealed using a Weather Silicone of Neutral Cure preferably matching the colour of the Upvc Window Frame or of white colour.
