Any domestic environment needs dividers to be able to differentiate rooms and preserve a space for everyone's privacy. It is therefore necessary to have closing elements, so as to circumscribe the bedrooms, bathrooms, living rooms, kitchens and more, subtracting them from the continuum of the building. Doors offer an effective and simple solution to this problem. They differ in multiple offers of hinged doors, internal, external, retractable, armoured, folding, fireproof and sliding, ideal for freeing the space from their own encumbrance. Available in different finishes such as wood, glass and more, the doors give the possibility to differentiate the house according to one's taste or needs of the individual.
