Sound absorption for suspended ceilings - PES for truss ceilings

SilentDirect PES 592x592 – Sound Absorber for Grid Ceilings

SilentDirect PES 592x592 mm is a professional sound absorber specifically designed for installation in standard grid ceilings. The product is developed for environments where improved acoustics, easy installation, and a discreet ceiling appearance are important, such as offices, schools, conference rooms, healthcare facilities, retail stores, and other public or private indoor environments.

With a thickness of 50 mm, an optimized density, and an NRC value of 0.94, SilentDirect PES provides very high sound absorption in a format that fits directly into the grid for 600x600 mm modules. The absorber is made of 100% polyester, at least 30% of which is recycled material, and is free from adhesives, irritating fibers, and harmful chemicals.

Effective sound absorption in a modular format

SilentDirect PES 592x592 mm is designed to reduce reverberation and minimize disruptive sound reflections that often occur in rooms with hard surfaces and open ceiling areas. With an NRC value of 0.94, the product absorbs up to 94% of incident sound, resulting in a significantly improved acoustic environment compared to many traditional suspended ceiling tiles.

Traditional ceiling tiles in suspended ceilings are often thinner and have a higher density, which can result in poorer sound absorption. SilentDirect PES, on the other hand, combines a 50 mm material thickness with an open, sound-absorbing polyester structure. The result is improved acoustic comfort, clearer speech intelligibility, and a quieter environment for work, teaching, and meetings.

Directly adapted for grid ceilings

The 592x592 mm format is specifically designed for standard grid ceilings and serves as a direct replacement for traditional 600x600 mm modules. The product can be used in new installations, renovations, or as a targeted solution in areas of the ceiling where the acoustic environment needs improvement.

The absorber is placed directly into the ceiling grid without the need for glue, screws, or separate hangers. This makes installation quick, clean, and simple. If necessary, the material can be cut with a knife to fit around light fixtures, sprinklers, ventilation, or other technical installations.

Safe, hypoallergenic, and moisture-resistant material

SilentDirect PES is made from 100% polyester and is completely free of adhesives, irritating fibers, and harmful chemicals. Unlike some traditional mineral wool-based ceiling tiles, the product does not shed dust or release fibers, making it particularly suitable for sensitive environments such as schools, offices, healthcare facilities, and public spaces.

The material is odorless, dimensionally stable, and mold-resistant, and is not adversely affected by humidity. The product is CE-marked and fire-rated according to B-s1, d0, making it a safe choice in environments where both safety and long service life are key requirements.

Discreet design with a textile feel

The surface consists of compact needle felt with a slightly mottled textile feel. This creates a soft, discreet, and professional look that blends well into both modern and classic ceiling environments. The neutral surface allows the absorber to be used across large ceiling areas without dominating the room’s visual appearance.

SilentDirect PES 592x592 mm works just as well as a full-coverage acoustic solution in a fully suspended ceiling as it does in combination with existing ceiling tiles. This makes the product flexible for both large-scale projects and minor improvements to existing spaces.

Lightweight and easy to handle

Each absorber weighs approximately 0.7 kg, making it easy to handle during installation and minimizing the load on the sub-ceiling. The low weight also makes the product practical for larger installations where many panels need to be installed or replaced.

Despite its low weight, the absorber has a stable and dimensionally stable construction that retains its function over time. It requires minimal maintenance and can be easily cleaned as needed by vacuuming or gentle wiping.

A sustainable solution for better acoustics

SilentDirect PES 592x592 mm is made from at least 30% recycled material and is recyclable. This makes the product a more sustainable choice for projects where acoustic environment, material selection, and long service life are important factors.

For those looking to improve the acoustics of a grid ceiling without complicated installation, SilentDirect PES 592x592 mm is an effective and well-thought-out solution. The combination of high sound absorption, easy installation, safe materials, and a discreet design makes the product a strong alternative for both new and existing suspended ceiling systems.
