Patterns

Walls

Membrane systems incorporating perforated patterns naturally have an acoustic dampening effect because they allow sound waves to enter the ceiling or wall cavity to be absorbed by the materials from which they are made.

For even better comfort, Velaria Systems offers an Enhanced level of acoustic performance by adding sound absorbing material behind the membrane.

Here are some examples.

Good for People and the Environment

All membranes have an A+ rating for air quality emissions and are 100% recyclable.

Sustainability is becoming a fundamental requirement of any design. With Velaria Systems not only do you get amazing design choices, superior acoustic performance, and the option for the best quality lighting – you also get system that is good for people and good for the environment.

We Make Specifying Your System Easy

Using our simple process, specifying a pattern membrane system is easy.

  1. Select your color or image for the membrane that will have a pattern
  2. Select your pattern from the nearly 400 options
  3. Select your backing membrane color
  4. Enhance the acoustic performance (or not)
  5. Add backlighting (or not)
