The benefits of invisible fastening systems for wooden wall cladding are the same as those for terraces: quicker fitting, no nails or screws in the planks or boards, no splinter formation, a longer lifespan, and a much better-looking result since there are no visible fasteners. Although wooden wall cladding is subjected much less to mechanical pressure (you simply don’t walk on it), several of these systems are nevertheless recommended all at once for both terrace wood and wall cladding.

Other points for attention It sounds rather strange, but there are some renowned and greatly respected technical bodies in the construction industry which still ignore invisible fastening systems. There are all sorts of regulations regarding the initial damp content of the planks, the choice of wood sort, the nature (width) of the profiles, ventilation, fire safety, and such like. As far as invisible fasteners are concerned, there is hardly any technical input at all. We can therefore say that vendors of these systems are some way ahead of the market. And so, it is no surprise that those vendors are usually the same ones who have made a (patented) spearhead of invisible fastening for wooden terraces. The visible dictates the invisible The visual possibilities are infinite in various ways. For instance, you can cover an entire wall with wood, a part of the wall, or even simply add a highlight. As regards plank sizes, there are no limits. The possibilities range from narrow slats of barely a few centimetres wide to panels of one or more square metres. Visually, the size gives an entirely different picture. You can use varying widths. Then there is the choice between horizontal and vertical fitting and between ‘open’ or ‘closed’ planks. The latter in particular has a huge impact on the substructure, especially as regards the ventilation.

Protection against damp Two elements are vitally important in the context of protection against damp: the creation of an air cavity and the provision of a damp screen. The damp screen, which is obligatory for most types of fitting, should be fitted continuously onto the insulation along the side of the air cavity. The screen should be watertight, airtight and damp-proof. The damp screen should have an md value (also called an sd value) of 0.5m. In the case of open wall cladding you should choose a damp screen which can withstand UV rays, frost, and wind.

Vertical and closed: what about the cavity? With vertical planks the support beams (rafters) obviously run horizontally. And so, with continuous rafters there should hardly be any adjoining cavity behind the planks, so that there is little or no ventilation. Strictly speaking, there are two solutions so that you can still ensure a well ventilated cavity for closed vertical planks in order to avoid fungus: horizontal slats with a number of breaks to facilitate an upward air stream and fitting double horizontal slats onto vertical planks.

Horizontal slats with recesses Lots of ingenious discoveries are quite simple. That is no less the case for Ventiwood®. The rafters have a recess at regular intervals so that they are ventilated. This not only yields excellent ventilation (>100cm²/m), but also the fitting can be done rapidly. The rafters are 33 x 60/41mm and 3.60m long.

Invisible fastening Most clip systems for terraces are designed to absorb the movements of the floorboards. They are designed in such a way that the wood can swell and contract if you ensure the correct distance between the sections. To that end, the humidity level of the wood is taken into account during the fitting. Clip systems draw a distinction between wood which is dried in conclave and wood which is naturally air-dried. An advantage: The fitter no longer needs to take account of the wood swelling. The clip indicates how far the planks have to be kept apart from each other. The existing systems require a groove (cutting) in the side of the planks, a groove underneath the plank, or no groove at all. The latter case has the advantage that all planks in all sizes are suitable. What’s on the market ?

B-Fix

For B-Fix it seems that the wooden wall fastening market is in a constant state of flux. There is great interest from architects in the many possibilities. The B-Fix fastening system is deployed for both terraces and wooden walls. That is a conscious choice; after all, it simplifies the work of both traders (e.g. with stock) and fitters, who only have to work with one system. For wooden wall cladding it is possible to fit the planks vertically or horizontally. For fitting with B-Fix there are no special points for attention, but, as with all wall cladding, you have to consider the structure, damp, and ventilation. The B-Fix system will mean higher purchase costs for the material, but, on the other hand, the system does offer huge time savings on the fitting and it does yield a much more attractive finish. B-Fix can be deployed for various materials.

Burger

Wood is a noble and durable material and people really love its aesthetic aspect. That applies to both private individuals and professionals, especially architects. At Burger, they are sure that screws will disappear from walls. Their R & D department has developed the rails + clips system for fastening wall cladding. With this system, no longer is each individual plank screwed in place, but fastened with clips. They offer four types of profiles and three wood sorts with various profilings. This wood comes from sustainably managed forests, so it is suitable for all projects. - Brushed thermally treated pine (2.70 to 4.80m) - Planed thermally treated ash (1.50 to 3.60m) - Planed Accoya® (3.00 to 4.80m) Their system has lots of advantages: - Quick and easy fitting - Perfect air and creeping distances and enclosures between the planks - Invisible fastening elements - Individually dismountable planks - A structure with a 30-year guarantee. Their system complies with the standard NF DTU 51.4. Their wooden profiles make 128 combinations possible over one metre. Each home is unique.

NOVOWOOD NOVOFIX

Contemporary architecture is often defined by attention to the detail, therefore Novowood R&D puts a lot of effort into the design of the fixing systems for its Wood Plastic Composite cladding elements. WPC Louvers can be used for wall cladding with very interesting results, therefore Novowood provides a lot of solutions for fixing the brise-soleil to the structure without any visible element. One of the most interesting is the Novofix System, an exclusive Novowood solution. The first step requested by this system is the creation of holes in the wpc profiles, that allow the insertion of particular connectors on the inner aluminium frame. The brise-soleil are then assembled with the bearing structure through special hidden fixing elements. The aesthetic result is extremely minimalist, since the connectors are completely hidden and not visible from any point of view.

Plastivan/Durasid® NATURAL WOOD LOOK WITH THE EASE OF MAINTENANCE AND DURABILITY OF PVC Plastivan NV, with more than 50 years of experience in the extrusion of PVC & WPC building profiles, launches a new and revolutionary range of cladding. Via a unique process of digital printing, the rigid foam façade panels are provided with a realistic wood design that can hardly be distinguished from natural wood. Durable and longer lasting appearance Rigid foam is a durable and resistant plastic that withstands the rigours of time and weather. You will never have to paint or oil again. A warm and natural look A print with a natural appearance is applied to the co-extruded protective top layer. This gives them a warm, natural look and means that DURASID® sidings can barely be distinguished from real wood. Simple to put in place DURASID® profiles are considerably lighter than equivalent products in solid wood or fibre cement. Installing them is therefore easier and they make less heavy demands on the facade or the supporting structure. In addition, the tongue-and groove joints make them quick to install. Easy to maintain The top layer makes sure that the structure is closed. Dirt and green algae deposits can therefore not penetrate the top layer of the material, a problem that does often occur in porous materials such as wood and fibre cement. Perfectly impact-resistant The material is known for its superb impact resistance. With alternative materials, impacts may result in a permanent dent relatively quickly, or may even crack the profile. Protecting and upgrading the outer wall DURASID® sidings protect your outer wall and add value to your home. The panels also protect any isolation layers inside, against all kinds of weather, guaranteeing that optimal insulation will be retained in the future. Environment Durasid rigid foam cladding fits perfectly into the context of sustainable construction. Production waste is recycled and used cladding at the end of its life cycle can be completely recycled. The estimated lifetime exceeds that of conventional wood or other alternatives. It is also easy to maintain so that no harmful products are needed such as paints, oils, varnish, lacquer, mold and algae resistant products ... More information on www.durasid.com
