The internal sliding doors, compared with the hinged doors, allow to take advantage of more space. The environments of the house, starting from the day area, become wider and more comfortable and you can furnish them with more freedom, enhancing also the comfort level. The sliding doors are of two types: external wall and concealed. The first type has one or more doors that slide in parallel to the wall. The installation and mounting do not require peculiar constructive interventions, since the doors are directly hooked with a track fixed to the wall or to the ceiling.

The main differences of the internal sliding doors

The internal sliding doors external wall represent the ideal and practical solution to close with elegance and efficiency passage areas or niches that are created for example by the protrusions of pillars, columns or flues. Concealed doors, on the other hand, are recessed and equipped with a special counterframe that guarantees a more minimalist aesthetic impact. In the case in which it is required a slightly more complex building work, it is necessary to break down a wall or a part of it.
The main difference between those external wall and the concealed sliding ones is therefore this: the former remain visible and slide on one side of the wall, which must then always remain free; the others, when opened, disappear because the door falls entirely within the thickness of the wall. The other difference concerns the masonry intervention, not necessary for the external wall doors and indispensable for the concealed ones, always if they have not been prepared. In both cases, however, these are solutions that allow you to save a lot of space and that offer satisfactory results also from an aesthetic point of view.

Assembly previews

Installation and assembly do not require any special wall work, as the doors are directly attached to a track fixed to the wall or to the ceiling. The tracks can be installed flush to the wall by means of a special aluminium structure that allows the sliding tracks to be concealed with an excellent aesthetic result. All the concealed doors are now real furnishing elements, the highest quality ones are also characterised by a refined, essential and classy design.
