Aluminium interior and entrance doors : Internal Hinged Doors With Glass
Quote from Article entitled Aluminium interior and entrance doors:
Aluminum doors can be relatively divided into “cold” and “warm”. For “cold” aluminum doors there is no requirement of heat-insulting characteristics, they are made of a shape without special thermal bridge. They are used mainly as interior doors in houses. These constructions fit well in door apertures where aluminum is used the most and also in doors of utility rooms and various storage facilities and so on.
