What are the maximum dimensions of windows and front door WITHOUT an impost?

Can you please advise – what are the maximum dimensions of these items can be produced in companies with a guarantee and WITHOUT the impost, given that neither on the profile (in terms of thickness and reinforcement), nor on the insulating glass (glazing, triplex, etc.) are not looking for a compromise?

1) Deaf window with lamination on both sides.

2) Front door with lamination on both sides

3) Front door, double leaf, hinged, laminated on both sides.

P. S. Is aluminum profile a replacement for PVC in terms of thermal conductivity and equal to it in price or not?
