Description
The wooden grill (grid) ceiling system consists of solid wooden slats that are secured to each other with aluminium or flexible plastic dowel clips. These assembled slats form the grill panel, which can be produced in various lengths. This is determined by the structural conditions and ultimately decided by mutual agreement. The grill panels are seamlessly fitted into one another with a half-lap dowel joint, which produces the visual effect of a single uninterrupted surface.
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

Specifications
Dimensions
For the grill ceiling 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 the 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.
Application
Interior ceiling
All versions of the Derako solid wood grill system are suitable for use as an interior ceiling. 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 slide into each other by means of a half lap dowel joint and are hung from galvanised steel rails with specially developed dowel clips. The grill systems are finished in black Sendzimir so that they are minimally visible. 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. The Derako advisers will be pleased to inform you about the possibilities.
Exterior ceiling
The solid wood grill system can be used outside below a canapé in several variants. The wooden slats, including the end sides, are then finished for exterior use. The carrier system must be fitted to the ceiling of the building structure with rigid materials.
Curved ceiling
The solid wood grill system is ideal for use in curved or arched shapes. The architect's creativity is the guiding principle and the system itself is not a limiting factor. Just as for use on a flat surface, the unique carrier system comes completely prefabricated. The rails are fixed and shaped in advance in the factory, to the desired radius. They can be suspended with quick action hangers or nonius hangers. The panels´ standard aluminium dowel is replaced by a flexible dowel.
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.
Fan panels
Fan grill panels not only offer a practical solution for the realisation of cylindrical grill ceilings or bends, the panels can also be used to create special organically and casually formed ceilings. The panels' radii are totally tuned to your project, while the engineering and definition of the lay-out plan will be taken care of by Derako. You will find examples of the implementation with the projects Galeria Mokotów and the C.C. plaza Genipa.
Finish / installation
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.
Fire stable
The Derako grill ceiling system has been assessed for fire stability in accordance with the Belgian standard NBN 713-020 whereby it has been officially established that the system meets the fire stability requirement of 30 minutes. It’s also possible to run the system in the B-S1-d0 classification.
Finish
The wooden slats may have a planed, fine-sawn and rough-sawn surface finish. Derako solid wood ceiling systems are finished as standard with high-quality varnish to protect the wood against moisture, dust and dirt. What is involved is a non-film-forming varnish that penetrates deep into the wood. Alongside the standard transparent varnish, there is also a wide range of colours available. The finish adds a nice touch to the wood and the natural tones and structures of the wood are preserved. For each application, the right system coating is determined that is necessary to protect the wood.
Construction and installation
As far as the installation is concerned, the grill system meets both the designer's and installer's demands. The made to measure grill panels are mounted to the black rails with specially developed dowel clips. For the side and 'in between' finishes Derako has developed profiles. 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
DismantlingBecause of the half lap dowel joints the grill system is completely demountable. It is possible to disassemble per two panels. From the visible side the dowel clips are fitted manually.
