We are a Aluminium Window Manufacturing factory and we manufacture windows on the basis of client's requirements. We don't manufacture and keep them for sale. 

Let's take an example: A client wants to install Aluminium Windows for his home. Obviously requirement would be like 2 windows of say 2.5 x 1.5 in the living room, 3 windows each in a three separate bedrooms of say 3.5 x 2. 3 fixed windows with louvers having size as 1 x 2 in three bathrooms. 2 windows of say 1 x 4 in Staircase an so on. 

An another client may need completely different window sizes. 

In my opinion, creating a new product template separately for each window is not right and feasible way to go ahead. 

I know that variants can be made as far as types of windows on the basis of fixed windows, viz. openable windows, three track - three Glass windows, two track - two glasses windows, three track - two glasses - one mesh and so on are concerned but I am not able to create a Product template because height and width combinations are infinite. 

Can someone here assist to to fix this issue and give me a solution. I might be missing something while designing the system. 

Thank you.
