Between the different shutter systems are used, the most common are:
- Ceiling-mounted system with tiles or panels preassembled
- System with visible screws fixed on morals
- System with concealed clips fastened on morals
- System with screws or clips mounted on height-adjustable moral anchored on spacers
The latter system allows greater rainwater drainage and greater aeration of the parquet as well as very valuable aesthetic that hides the normal slopes in outdoor floorings.Preliminary stages to installation
Forthe correct installation of exterior wooden flooring, it is necessary to pay specialattention to the aspects mentioned below.Drainage and/or background
The substrate on which it is to be fixed/adapted the parquet to the outside must be designed and constructed so as to ensure the rapid drainage of rainwater runoff and/or.Wood preparation before the laying
Prior to installation you can scrub the planks with water in order to avoid the release of tannins and/or extractives that my stain the boards and/or other adjacent floors.
This procedure is not necessary if you want to treat the wood with suitable preservatives and/or dyes for outdoor use. In the latter case you should treat the slats on all sides including the heads and/or any millings.Storage
As you can well imagine, the wood used for the exterior is constantly undergoing extreme temperature changes and humidity which alter the dimensional stability. However it is matured for a fixed degree of himidity determined by the manufacture (usually much longer than the wood used for interiors).
This procedure allows the slats to maintain good dimensional stability at least until the time of installation. For this reason, it is best to store the boards in a covered andwell ventilated, avoiding to subject it to extreme temperature changes that could alter the size of the planks making it difficult or impossible for a regular installation.
