GRANRU PORI – contemporary acoustic wall panel collage


GranRU Pori is impressive and new kind of acoustic wall panel collage inspired by traditional tufted rugs. In Pori the visual world of Finnish and Scandinavian traditional handicraft, lasting ecological materials and innovative processing methods are combined.

The Pori creates immediately a strong visual impression wherever it is placed. Work consists of six panels, measuring up to a total of HxW 2430x1760 mm.

The graphic pattern consists of hundreds of x’s, which are carefully either impressed or raised from the surface of the panel. In the end, there is almost limitless topology on the acoustic surface. Pori plays with fine details and calls for the user to take time, look and find more and more details and tulip motif inspired shapes/textures.


There are four standard colors to choose from: sheep white, black, gold and blue. Custom colors available by request

The acoustic material of the panels is surface peat moss, a 100% ecological Finnish patented innovation that is also acoustically ultra effective (absorption Class A). The material has really pleasant, organic and unique visual texture. There is literally piece of Finnish nature inside every panel.


For every panel there is a mounting strip fastened to the wall with two screws. After mounting the strips, the panel is ready to be hung on the wall. The mounting system maximizes the acoustic effect by creating a 25 mm air gap between the panels and the wall.


The GranRU PORI is equally suitable for offices, private homes and public spaces. The material has CE marking and M1 classification for indoor air quality. To minimize chemical strain on the environment there are no added fire retardants in the panels. The product is classified as a decorative element in spaces with restrictive fire class regulations. If needed please confirm the meeting of local fire requlations based on these quidelines.


Pori collage requires minimal maintenance. In the case of extensive dust collection, please use a regular vacuum cleaner with textile nozzle.
