WHAT IS ECHOLINEAR?

Echolinear is a patented sound absorbing system for ceilings and walls, comprising a streamlined, demountable fixing system, E0 and FSC® certified substrate and a seamless linear look. Designed to achieve the highest aesthetic and sound quality levels, Echolinear combines quality materials and superior acoustic capabilities with extremely simple installation.

HOW DOES IT WORK?

Echolinear can be considered as a number of resonance chambers assembled together, into which sound waves enter, mixed with air, through holes in the external surface. Once the sound waves are inside the chambers, they are dissipated by the friction experienced in the tunnels of air. Even if there is no free space or rockwool insulation behind the panels, the mechanism remains efficient in the absorption of medium sound waves, such as those of the spoken word.

ACOUSTIC ABSORPTION

The acoustic performance of sound absorbing materials can be generally described by a value known as the NRC or Noise Reduction Coefficient. The NRC is calculated as the mean average of the sound absorption values at 250, 500, 1000 and 2000Hz. NRC values of Echolinear vary with the different milling profiles and the method of installation.

Note: Rockwool used in our tests is 30mm thick, with a density of 60 kg/m3. Tests carried out in accordance with ISO 354.

STORAGE

You must store Echolinear packs indoors and protect them from moisture and humidity.

ACCLIMATISATION

48 hours prior to installing, open the Echolinear packs in the installation location and allow the planks to stabilise at the ambient conditions. The environment in which you are installing Echolinear must have been conditioned prior for at least 24 hours and have a temperature of at least 15C and humidity between 40% and 60%.

JOINTING

You have various jointing options when laying Echolinear planks end to end, including:

• leaving a gap between the two planks the same width as the milling
• butt-joining the ends in a random or hinged configuration and securing them together using the special joining springs (to a maximum of two planks).

When deciding between these alternatives, remember that the length of Echolinear planks can vary according to differing environmental humidity conditions (+/- 2mm per metre). Walls and/or ceilings requiring the jointing of more than two planks require expansion joints to be designed into the installation.

WALL INSTALLATION
Mounting System Structure

1. Metal omega rails 3000mm x 18mm x 24mm
2. Starter clips
3. Clips for anchoring planks to the omega rails and screws for securing the clips
4. Fixing accessories / either self tapping screws or screws plus expansion fixing, depending on the type of support (by others)
5. Rockwool insulation panels (by others)
6. Finishing clips to secure the last plank

Installation
Secure the metal omega rails to the wall at intervals of no more than 600mm and at right angles to the orientation of the the Echolinear planks. Then lay rockwool between the rails.

For horizontal orientations, mount the first plank with the female side towards the floor and secure it with the special starter clips, then insert the clips to anchor the male side. Mount subsequent planks above the first, securing them in the same way.

When mounting vertically, start from one side and proceed as above.

It is recommended that you screw fix at least every fourth clip to the support structure omega rail by means of the self tapping screws provided.

Edges can be finished with standard profiles shown below under Accessories.
