Facade construction 1.1. Product features High-density stratified panel with natural timber veneer for outdoor use Facade is a high-density timber faced panel, manufactured with a core of paper fibres treated with thermosetting resins. These are compressed at a high temperature and pressure and protected by an exterior coating highly resistant to UV radiation and weathering. Facade panels include Everlook®, a component introduced into the wood to provide outstanding life-cycle benefit in terms of colour stability, in all climatic conditions with no varnish need at all over the years. It also...

Physical properties Dimensional stability at elevated EN 438.-2 Part 17 Cumulative dimensional % max Longrain temperatures change The panels must be correctly strapped down for transport, bearing in mind that they slide over each other easily and may become damaged. They must always be transported horizontally. The panels must never be transported loose or with broken straps. For short trips, inside workshops or at the construction site, fasten the panels using straps whilst protecting the edges...

Standard requirements should be kept in mind when handling Facade panels, especially with regards to • Dust removal. • Dust collection. • Fire precautions, etc. Due to the possible presence of sharp edges, protective gloves should always be worn when handling Facade panels. Contact with dust from HPLs does not normally present a problem, although some people may be sensitive or even allergic to it. Parklex panels may be machined using conventional commercial grade carpentry machines equipped with hard metal accessories. Due to the high density of Facade, cutting speeds must be slower than those...

The main components for the Facade panels installation (aluminium, steel, timber and/or plastic) are easily separated for recycling. 1.6.1. Waste management information The specifications that rule the production and management of waste generated in construction and demolition must be fulfilled, as well as any current local regulation. The re-use of the Facade panels in other applications with different requirements is encouraged. It is possible the assessment of the waste by industrial incineration.

2.3. Choosing panel thickness Ventilated installation It is necessary to leave expansion joints around the perimeter of all panels and where they meet with other materials to ensure they can absorb any expansion movements. The thickness of these joints depends on the panel dimensions and the façade design. As an example, for panels measuring 2440x1220mm, these joints must be at least 6mm. It is recommended not to seal the joints with flexible materials, as this may lead to an accumulation of dirt around the edges of the panels. The required panel thickness is selected according to the element...

2.4. Three support points 2.5. Counter-sunk head screws not allowed Facade panels must be fixed to at least three points of structural support*. The distances between support points depend on the mounting type and the thickness of the panel. The instructions regarding distances that come with the various, commercially available fixing systems may be followed, as long as there are at least three points of support in each direction. Facade panel installation using counter-sunk head screws is not allowed as they do not enable free panel movement. * See exceptions in the table below. Profile distribution...

3. Installation system on ventilated façade

Facade panels must be installed as a ventilated fagade; therefore, they must be separated from the wall face by profiles, which are installed vertically, forming a chamber with a free ventilated space of &20 mm, except in those countries with specific technical documents. In the event that some type of insulation will be installed, a doubleprofile structure or a single-profile structure with adjustable supporting elements must be installed, ensuring that the chamber is maintained. To permit air circulation in the ventilated chamber, the air intake and output must be correctly proportioned. Head...

To facilitate air circulation behind the panels, a substructure of vertical profiles must be installed. The substructure must be designed according to the habitual wind load in the area and in such a way that it meets all static requirements. Account must also be taken of the façade inclination, the fastening system chosen, and the thickness and dimensions of the Facade panel being installed in order to establish the parameters applied. In addition, it must be perfectly protected against corrosion and rotting, regardless of the material or system used. The minimum support width of the profile...

Fixed point and floating point Centering the screw / rivet Panel Fixings All mounting points for Facade panels must be floating (with a diameter of at least 3 mm larger than that of the screw or rivet; see the next chapter), except for one, which must be fixed. This is the point around which the panel will expand and contract. This fixed point must be as close as possible to the center of the panel. The screw / rivet must be centered in the hole to permit dimensional variations. Facade may be installed using visible mechanical fasteners, such as screws or rivets lacquered in a shade similar to...
