Grill solid wood wall system

A wall application of the grill system consists of solid wooden slats that are fixed together with aluminium or plastic flexible dowels. Together, these assembled slats form the grill panel and are fitted into each other by means of half lap dowel joints. In this way one surface is created, without any interruptions . Just as for ceiling applications each panel is delivered to size, based on the building structure's data and in mutual consultation. The grill panels are, by means of wall clips, screwed directly onto the building structure's sub frame. There is no profile available for the connection length of the wall panels, but an open joint of at least 10 mm must be adhered to.

Solid wood

Derako works exclusively with solid wood. Each type of wood has it´s own natural characteristics such as colour, grain, structure, knots and size tolerance.

Derako system advantages

• Environmentally friendly. Wood is the only building material that is 100% CO₂ neutral and totally recyclable.
• The systems guarantee fast and simple assembly.
• Technical support. Projects are technically supported and developed.
• High acoustic values.
• Treated to be fire retardant according to EN13964.
• Using certified and preserved materials.
• Budget flexible and because of modular delivery very suitable for prefab building.
• Comprehensive warranty

Dimensions

With the grill wall system, you can, at your discretion, determine the sizes of the slats and the distance between the slats. The minimum slat dimension is 15 mm thick x 31 mm high. The minimum distance between the slats is 17 mm at a maximum slat height of 35 mm. If the slat is higher, the distance should be at least 20-23 mm. Depending on the wood species and availability of raw material, a grill panel can have a maximum length of 3300 mm. The distance between the dowels is a constant of 300 mm and dowel has a standard diameter of 12 mm. On request and with a certain slat dimension, it is also possible to use a 20-mm dowel.

Interior wall

The Derako solid wood grill system is suitable as  a sustainable interior  wall. On the basis of structural data and mutual consultation, Derako will determine the exact number of grill panels and correct length measurements. The grill panels are, by means of special wall clips, screwed directly onto the  sub frame of the building structure. Because of a wide choice of types of wood, dimensions of the slats and finishes, there are a number of possibilities for the  appearance of the ceiling.

 

Exterior wall

If there is a large overhang the grill wall system may also be used for outdoors. The wooden slats are then finished for exterior use. It is important that the wood is not directly exposed to weather influences. Not all kinds of wood are suitable for exterior walls. The Derako advisers will be pleased to inform you about the possibilities.

 

Curved wall

The grill wall system can also be used for curved or arched shapes. The walls themselves can either be curved or they can flow smoothly into the ceilings The architect's creativity is the guiding principle and the system itself is not a limiting factor. For a curved application the standard aluminium dowel is replaced by flexible dowels. Then the panels can be easily bent into the shape of the building structure´s sub frame and fixed by means of wall clips.

 

Specials

CNC panels

By using CNC milled panels Derako is also able to offer special made to measure solutions as well as the standard grill panels. With these panels very special designs can be realised. The special CNC panels also ensure, with a prefab delivery, a more efficient assembly and a reduction of costs. An example of this implementation can be found with the project Life Science Incubator.

Varying measurements

With the combination of varying slat heights, widths and joint distances within the grill panels, you will be able to give the ceiling (wall) a unique appearance. A random pattern ensures further reinforcement of the natural and casual effect, while there is a big choice of wood types and measurement combinations.

The wooden slats can have a planed, fine-sawn or rough-sawn surface finish. Depending on the request, the right type of finish can be selected in consultation with the Derako consultants.

Fire retardant treatment

Fire retardance is an important element for any wood application. To be able to comply with fire safety regulations, Derako systems are treated, if necessary, so that they are fire retardant. This is done by means of the vacuum and pressure method, whereby the wood is impregnated with a fire retardant substance. 

With these treatments Derako makes sure that the slats and panels, used as a coating/finishing material meet the European standard EN13964. The treatment process is performed according to KOMO guidelines and is periodically inspected by the SKH so that the required CE marking can be employed.

Finish

Designing a wall design with total freedom of creativity; this is not a problem for the Derako systems. In addition to various types of wood in a transparent finish, Derako also has a wide range of colours available. All versions of the wooden wall systems are finished as standard with a high-quality non film-forming varnish to protect the wood against moisture, dust and dirt. This finish adds a nice touch to the wood and the natural tones and structures are preserved. The wooden slats may also have a planed, fine-sawn or rough-sawn surface finish and for each application, the right system coating is determined that is necessary to properly protect the wood.

Construction and installation

As far as assembly is concerned the grill wall system meets both the designer´s and installer´s  demands. For the assembly of a grill wall project, the exactly made to measure grill panels  must be fitted to the underlying building structure or construction by means of special wall clips. Each grill project is developed by Derako themselves, and in addition to the products we  also supply a layout plan and a pot of matching varnish as standard. Under the tab 'Downloads' you will also find an extensive installation manual.

Dismantling

Because of the half Lap dowel joints the grill system is completely demountable. When using a demountable wall system incidental repairs and maintenance work can be carried out and when there is possible damage a grill panel can be easily replaced.

Wood has a limited environmental impact

Wood is a natural product, very durable and lasts for years. Industrial wood processing has a very limited environmental impact and wood itself stores CO₂. This helps of course to deliver environmentally friendly, healthy and responsible products. But Derako does more ...

Cradle to Cradle^®

Derako constructs and works according to the Cradle to Cradle^® principle that not only looks at our present needs but also at the possibilities for future generations. Within the five Cradle to Cradle defined quality categories, we are constantly working on improvements.

A+ certified

Derako wants to be sure that all products have a lasting positive influence on human health and the environment. A lot of thought is given to the system- and finishing materials. For example the Derako varnish finish is environmentally friendly and the Derako solid wood system has a very low emission and A+ certified.

FSC® and PEFC certified types of wood

In addition to investment in the field of materials and production processes, Derako also invests in various certificates and eco- labels. In this way we meet the criteria set by the government on sustainable purchasing. Derako is FSC® and PEFC certified and delivers systems on request, and where possible we deliver sustainable and certified types of wood. The advisors at Derako will be delighted to let you know about all the options.

BREEAM and LEED

Derako also has a number of system designs that can make a substantial contribution in obtaining credits from BREEAM and LEED. Derako's advisors will be delighted to inform you further.
