Exterior sliding doors, they are ideal for environments small, then slide flush with the wall for full opening. They come in many variants, which can be divided into two general groups: the outer guide and recessed. The sliding doors outer guide travel through guides nestled in sight, outside the wall, inside or outside the room. They are much simpler and faster to install, maintain and replace.
Recessed exterior sliding doors, however, they are hidden in walls or partitions once open. They should be installed at the time of the work, or project them from the outset to ensure a hollow wall that receives. They are much more aesthetic, and work with guidelines similar to the displacement above, only embedded in the wall and frame.
For the placement of exterior sliding doors you need to install a guide or recessed wall or outside lane. Indispensably, the guide is placed on top of the door leaf, either by wheels and rails, or grooves and channels. To more firmly and to prevent derailment, you can be placed lower guides, although they remain in sight on the floor. A good solution is to put them in the recessed bearings within the septum, which facilitate its opening but will hinder the removal of leaves for maintenance.exterior sliding doors
