Acoustic felt sample set (7-piece) – 3x Polyester (10 mm) & 4x wool felt from 100% sheep wool (4.5 mm) Acoustic felt sample set (7-piece) – 3x Polyester (10 mm) & 4x wool felt from 100% sheep wool (4.5 mm)

The sample box contains material samples of our acoustic felt made of 100% sheep's wool in 4.5 mm quality. The felt is intended for indoor use and is suitable for assessing the color effect, surface appearance, material thickness and feel before processing larger areas.

The acoustic felt has a material thickness of approx. 4.5 mm and, with a specific weight of 0.17 g/cm³, has a dense material structure. The quality is designed for applications on walls, ceilings, panels and cladding surfaces in interior design. Typical areas of application are living rooms, offices, studios, store fitting and other commercial areas.

The samples serve as a basis for decision-making for projects in which a textile surface, a defined material thickness and a uniform surface appearance are paramount.

Application: Which material is right for your project?

Both polyester and wool felt effectively reduce room noise and reverberation. They differ primarily in their material properties:

• 10 mm polyester (PES) acoustic felt:
  The functional specialist for maximum sound absorption (up to 97% in the high-frequency range) with high material thickness. Durable, hard-wearing, and ideal for high-traffic areas or acoustic panels.
• 4.5 mm wool felt made from 100% sheep’s wool:
  The natural alternative that combines sound absorption with organic indoor climate properties. The dense structure made of pure wool regulates humidity and creates a uniform, matte surface.

Frequently Asked Questions (FAQ)

• Will the self-adhesive felt stick to my wall?
  Yes, on clean, smooth, and dust-free surfaces. First, conduct a 24-hour adhesion test using the sample directly on your surface.
  
• How do the materials react to humidity?
  Wool feltis highly breathable and can absorb up to 33% of its own weight in moisture and release it in a controlled manner without feeling wet.
  Polyester fibersdo not absorb moisture themselves and are moisture-resistant.
  
• Does the wool felt smell like wet sheep's wool?
  No.Our wool felt is cleaned and odorless. Sheep's wool actually actively filters and neutralizes odors and harmful substances (such as formaldehyde) from the air in the room.
  
• How much acoustic foam do I need to achieve a noticeable improvement in acoustics?
  As a general guideline for effective reverberation reduction, cover approximately 30% of the room’s floor area—either by covering walls and ceilings or using panels.
  
• Can I remove the self-adhesive felt without leaving any residue?
  The adhesive provides a strong, permanent bond.Tip for rental apartments:Stick the felt onto thin backing boards (e.g., plywood) and hang them like pictures.
  
• How do I cut the materials cleanly?
  Use a sharp utility knife and a metal ruler. Always use fresh blades to ensure perfectly clean, fray-free edges.
