Window and door prices depend on the customer's wishes. For example, different types of glass packages are currently available for windows. Which in a way also makes up the price of the window and the thickness of the window.

A wooden window with a 3-glazed unit remains quite popular at the moment, where the total thickness of the double-glazed unit is from 32 to 48 mm. Which in turn immediately increases the cost of the window. 
We can make wooden windows with any of these sizes.

It is also possible to put more expensive fittings inside the door, when you can adjust the door in 3D ways or cheaper and simpler fittings. Of course, the price is also determined by your desired door sizes.
