NORTO Toft

THE CEILING CONSTITUTES AN ESSENTIAL PART OF THE ROOM. IT CAN ALSO SERVE AS ITS STRUCTURAL ELEMENT AND, IN ADDITION, IT CAN ALSO PLAY A KEY ROLE IN ACOUSTICS. IN THE NORTO TOFT PRODUCT, WE HAVE COMBINED ALL THESE ELEMENTS TOGETHER TO ACHIEVE A FULLY BALANCED ASPECT OF THE CEILING.

NORTO Toft

Sustainable acoustic ceiling solution

NORTO Toft is the new wooden ceiling in our NORTO CeilingUP range. During the development of this wooden ceiling we have placed an emphasis on achieving an appropriate acoustic effect. During its creation, we experimented with various patterns, shapes, functionalities, materials, styles and aesthetics.

NORTO Toft

Product description

NORTO Toft is a durable ceiling panel made of solid residual pine wood. Each panel has a different pattern with milled grooves with rounded edges. These different patterns create vivid and spatial expressions on the panel structure. NORTO Toft has a natural design with visible knots and rings. The ceiling covering should be fitted with an acoustic membrane so that sound can be suppressed, thus creating the best conditions for good room acoustics. There are two types of this product. The first one has a slotted milling outlet in the shape of longitudinal grooves. The second type has milled grooves that are not drilled through. It is also possible to use NORTO Toft as an acoustic solution for walls.

Sound test of the NORTO Toft acoustic panel

The acoustic panel NORTO Toft has been sound tested in cooperation with Sound Hub Denmark, the first international technology- and innovations hub for entrepreneurs and start-ups working with sound and acoustic. The product has been tested in a specialized reverberation chamber in the old product development facilities of Bang & Olufsen in Struer, Western Jutland (Denmark). The acoustic engineer, Peter Chapman, has testes the product and analyzed the results.  

The NORTO Toft has been tested to see the sound absorption by some standardized frequencies. It is possible to compare the data of the test with other acoustic products to look at the sound challenges in the room. The NORTO Toft panel has milled grooves, that create differences in the surface structure. The acoustic panel can be mounted on an underlying felt. This construction creates optimal conditions for sound reduction in the room. 

The NORTO Toft acoustic panel has been tested on different installationsThis means, that the underlying construction can fit the sound problem in the concrete room. Some examples are shown in the graph below. 

When mounting on a thin felt with a hard underlay, the NORTO Toft panel absorb 45 % of the sound by high frequencies. To achieve an optimal absorption on lower frequencies, mineral wool or felts behind the panels are good materials in that case. Then it is possible to achieve aabsorption coefficient around 0,9.
