Design and cusomisation come together.


Grill Pro-line

We custom build Grill Pro-line according to your specifications. It’s a tailor-made ceiling solution. Your design and budget are our starting point. Derako offers full support during the orientation phase, engineering, logistics handling and installation. This ensures a product that fits perfectly. The system combines high-quality solid wood panels with the Derako suspension system.


Grill Pro-line offers a broad range of wood types, sizes and finishes. All panel lengths are listed in a detailed installation plan. This allows us to guarantee stylish ceiling lines and efficient installation at minimal cost. The system can also be used for curved or arched shapes.






Tailor-made panel system

For Grill Pro-line, we produce all panel lengths on the basis of the architectural design. The panels consist of solid wood slats which are attached to each other using aluminium dowels. You select the dimensions of the wood and the spacing. We produce the panel with the desired appearance. Aluminium dowels are available in two diameters, 12 mm or 20 mm. The standard colour is black, but other colours can also be used for Grill Pro-line. This gives the ceiling an exceptional appearance.


The connection between the panels is quickly realised via the half-lap dowel connection. This allows you to create a visually even surface and a smooth appearance. We guarantee stylish ceiling lines and efficient installation. All grill ceiling systems consist of a combination of solid wood panels and the Derako suspension system.


Derako suspension system

The Derako suspension system is a black Cross-Lock system with special black dowel clips. These clips ensure an invisible, dimensionally stable and sturdy connection between the Cross-Lock profile and the grill panel. The system is also suitable for installation in staggered patterns and in curved or arched shapes. Special suspension systems are available for swimming pools and extremely humid spaces.

Grill Pro-line is a suspended ceiling system. You can see an overview of the system structure in the image below. The system is also suitable for walls. The design of the ceiling and wall can merge into one another. Please see our wall application for more information.

You can determine the dimensions of the solid wood slats and the spacing yourself.  
The most common sizes are:

Thickness wood (B) 15 mm to 35 mm
Height wood (C) 40 mm to 140 mm
Joint (A) 25 mm to 140 mm


Other sizes available upon request and in consultation.
The lengths of the composite panels vary between 590 mm and 3590 mm. This differs per wood type.


You can see a number of possibilities in the table below. These are only a few cost effective examples from the enormous range of options.

Wood and finish

Grill Pro-line includes a wide variety of wood types. Derako only uses top quality solid wood and bamboo. During the production process, our people select the best parts.


If you would like to use a different wood type, this is in many cases possible. We of course examine whether this wood type is suitable for our production process and the application.

The solid wood grill panels are as standard provided with a high-quality lacquer finish that protects the wood. This non-film-forming finish prevents wood damage caused by moisture, dust and dirt. The finish penetrates deep into the wood, but the natural properties and structures are maintained. The lacquer system structure is tailored to the application. In addition to the standard transparent finish, a large number of colours are also available. Our machines can produce every desired colour.


Get creative with colours

Would you like to do something special with colours? Multiple tones in a ceiling, striking colours or expressive contrasts with the neutral wood? Ask our advisors about the possibilities and create your own style and unique appearance.

Due to its shape, processing and the natural properties of wood, Grill Pro-line is sound-absorbing. Extra attenuation can be achieved by placing a sound-absorbing (sheet) material behind the systems. This extra attenuation creates a pleasant atmosphere, also in buildings where many people congregate at the same time.


Acoustic non woven tissue - made to measure

You can optionally order acoustic non woven tissue separately. Black is the standard colour. The non woven tissue fabric is delivered including an excess length of 50 mm on both sides. During the installation at the construction site, the acoustic non tissue can be attached to the back of the panels.


Eco Silent Panel - Designed Specifically for the Grill System

Panels specially developed for the Derako Grill system. The acoustic panels are made of polyester wool. 60% of the wool fibers are sourced from recycled PET bottles. Additionally, polyester wool does not contain unwanted chemical binders or toxic substances that can cause allergic reactions or skin irritations.

Building with solid wood is very ecologically responsible. The material has minimal impact on the environment, is fully biodegradable and renewable. Wood is virtually 100% CO2 neutral and has a permanent positive impact on the health of humans, the environment and the surroundings. All Derako systems are fully demountable. At the end of their lifespan, the materials are separated. The mono-components and natural raw materials that remain can be reused in the circular economy.


Cradle to Cradle

Derako designs, builds and works according to the Cradle to Cradle® principle. We want to take care of future generations. Each material must be fully reusable, without losing value. We have had our processes certified. There are five levels of certification: Basic, Bronze, Silver, Gold and Platinum. Derako is C2C Silver certified.


FSC, PEFC, A+, ISO certification

Derako invests in sustainable business practices. We use wood types with FSC® or PEFC certificates. We evaluate finishing materials on their ecological footprint and have VOC A+ certification. In addition, we embrace the quality and environmental management systems ISO9001 and ISO14001.
