Quick and easy panel system.


Grill Base-line

Grill Base-line is our standardised ceiling system. You can choose from fifteen sizes, four wood types and three fixed panel lengths. Derako can produce quickly and inexpensively thanks to standardisation. You can order easily, per panel, via the Derako order form.

The system consists of high quality solid wood parts that are attached to each other with aluminium dowels. Together they form the grill panel. The panels are fastened to the structural ceiling invisibly and easily using the Derako suspension system.






Standard panel solution

Grill Base-line combines solid wood ceiling panels with the Derako suspension system. These solid wood parts are attached to each other using black aluminium dowels, creating a panel. Grill Base-line is a standard panel solution. You can choose from a number of sizes for the thickness, height and spacing. We produce the wood to size and shape it into a panel. With a half-lap dowel joint, the panels are quickly and easily connected and assembled. This allows you to create a visually even surface and a smooth appearance.


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 suitable for installation in staggered patterns. Special suspension systems are available for swimming pools and extremely humid spaces.

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. Grill Base-line is available in any desired colour and with a transparent appearance.

Circular and responsible product

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.
