Fire Resistant Acoustic Felt Panels

Fire Rated Wall Panels

Our fire-resistant acoustic PET felt panels are the premier choice for projects where safety standards are non-negotiable. Designed specifically for the B2B market, fire rated wall panels sheets from DeFelt combine high-performance sound absorption with superior fire safety, achieving the B-s1, d0 classification. This makes them ideal for wall cladding and acoustic treatments in schools, hospitals, hotels, and corridors where fire regulations are stringent.

Despite their specialized treatment, our fire resistant acoustic panels retain the tactile appeal and eco-friendly nature of recycled PET and are consistent with the zero-waste idea. Available in various densities and thicknesses of 9 mm, 12 mm, 24 mm and also boasting a range of 72 vibrant colors, fire resistant wall panels offer limitless design potential for custom fabrication. Upon special customer request, our DeFelt machinery park is also ready to produce fireproof felt panels with thicknesses of 18 mm, 27 mm, 36 mm, and 48 mm.

By using our FR panels, manufacturers can ensure their end-products meet the necessary legal requirements for contract use. Partner with us for a steady supply of certified, safe and versatile acoustic materials that protect both people and design integrity.

Fire resistance standards – class A vs. B-s1, d0

Understanding fire resistance standards is essential when selecting fire-rated acoustic panels. Depending on the region, different classification systems are used to describe how a material behaves in the event of a fire.

• Class A (USA): this is the highest fire resistance rating in American standards. Materials classified as Class A have a very limited contribution to the spread of fire and smoke.
• Class B-s1, d0 (Europe – EN 13501-1): this is the European classification for products with very limited combustibility. The designation indicates:
  • B – very limited contribution to fire development
  • s1 – very low smoke emission
  • d0 – no flaming droplets or particles

Our PET felt panels are certified B-s1, d0, ensuring safety and compliance with strict European fire safety standards. Comparing these classifications helps provide a global understanding of our products’ fire performance.

Simple and versatile installation methods for fire resistant acoustic panels

Fire-rated PET felt acoustic panels are designed for quick and easy installation, offering flexibility depending on project requirements.

• Direct adhesive installation: the most common method, providing a durable and visually clean result. We recommend using professional mounting adhesives designed for porous surfaces.
• Velcro mounting: an ideal solution for temporary installations or where easy removal and rearrangement of fire-rated panels is required. Strong industrial Velcro ensures sufficient panel stability.
• Rail and profile systems: for more advanced projects or spaces requiring additional ventilation or specific panel arrangements, fire-rated panels can be installed using dedicated rail systems, creating an aesthetic and functional acoustic solution.

Thanks to this versatility, DeFelt fire-rated panels easily adapt to any environment, from offices to residential interiors.

Care and maintenance of DeFelt fire-rated panels

PET felt fire-rated acoustic panels are designed for durability and easy maintenance. To preserve their appearance and acoustic performance for many years, we recommend following these simple care guidelines:

• Vacuuming: regular vacuuming with a soft brush attachment is usually sufficient to remove dust and minor dirt.
• Stain removal: if stains occur, gently clean the area with a damp cloth. Avoid strong chemical detergents that may damage the material or alter its color. Always test any cleaning product on an inconspicuous area first.
• Avoid excessive moisture: although felt panels are moisture-resistant, they should not be soaked. If a panel becomes wet, allow it to dry naturally in a well-ventilated space.

Types of fire-rated acoustic panels

The market offers a variety of fire-rated acoustic panel solutions that combine aesthetics with safety.

• PET felt panels: our panels, made largely from recycled PET bottles, are an excellent example of this solution. They are lightweight, impact-resistant, and available in 72 colors, offering great design flexibility. The panels are fire-treated to enhance their fire resistance and meet strict European B-s1, d0 standards.
• Mineral wool panels with felt finish: another type consists of panels with a non-combustible mineral wool core covered with a felt surface layer. These provide strong fire protection while also acting as effective sound absorbers. They are typically used in applications where maximum non-combustibility is required.

At DeFelt, we focus on innovative PET felt panels that offer the ideal balance between acoustic performance, fire safety, aesthetics, and sustainability – qualities valued by our long-standing clients and business partners.
