Sound absorption for ceilings - PES ceiling

SilentDirect PES Ceiling – Discreet and Effective Ceiling Sound Absorption

SilentDirect PES Ceiling is an advanced and stylish sound absorber for ceilings, designed to provide effective sound absorption in everything from offices and schools to studios, industrial environments, and residential spaces. The product is available in five sizes: 592x592mm, 800x800mm, 1000x1000mm, 1200x600mm, and 1200x900mm, all with a thickness of 50mm. The absorber is made of 100% polyester and is completely free of adhesives, irritating fibers, and harmful chemicals, making it particularly suitable for sensitive indoor environments.

With its compact needle-punched surface and straight-cut edge profile, SilentDirect PES Ceiling fits just as well in modern environments as in more traditional settings. It reduces reverberation, absorbs disruptive noise, and contributes to a more balanced and pleasant acoustic environment in everything from open-plan offices to home offices and creative spaces.

Create acoustic balance in all indoor environments

SilentDirect PES Ceiling is specifically designed to manage sound reflections on ceilings, where echoes and reverberation are often amplified. By absorbing sound early in the room, overall acoustics are improved, and the sound environment is perceived as calmer and more controlled. The result is reduced stress, better speech intelligibility, and increased concentration—whether the environment is an office, a classroom, a studio, or a home. In office environments, the absorber contributes to increased well-being and focus. In schools, it improves the study environment and speech intelligibility, while in industrial facilities it reduces noise from machinery and technical equipment. In homes, SilentDirect PES Ceiling creates a more harmonious atmosphere in living rooms, bedrooms, and home offices. It is also ideally suited for design-oriented environments such as restaurants, yoga studios, and dance studios where aesthetics and function need to work together.

Easy and flexible installation

SilentDirect PES Ceiling is designed for simple and flexible installation. The absorber can be mounted flush against the ceiling or with a gap to create an air gap, which further improves sound absorption. The 592x592mm size is adapted for standard grid ceilings and works excellently both for new installations and as a replacement in existing suspended ceiling systems. The larger formats are installed freely using brackets, wire, screws, or adhesive, depending on the desired look and acoustic requirements. Brackets and wire systems are available as options and allow the suspension to be adapted to the room’s layout, ceiling height, and aesthetic requirements.

Environmentally friendly, safe, and hypoallergenic

SilentDirect PES Ceiling is made from 100% polyester, at least 30% of which consists of recycled material. The product is free from adhesives, chemicals, and irritating fibers, making it a safe choice in environments with high standards for health and indoor air quality. It is hypoallergenic, odorless, and mold-resistant, and is not adversely affected by humidity. The absorbent is fire-rated according to B-s1, d0 and CE-marked in accordance with European standards for construction products. This makes SilentDirect PES Ceiling suitable for use in both public and private environments where safety, sustainability, and long service life are crucial.

Customized to your needs – sizes and technical information

SilentDirect PES Ceiling is available in five sizes: 592x592mm, 800x800mm, 1000x1000mm, 1200x600mm, and 1200x900mm, all with a thickness of 50mm. The smaller size is designed for exposed ceiling structures, while the larger formats offer great flexibility for free-hanging or flush mounting. The weight of the absorber varies depending on size, and it features a smooth, durable needle-punched surface with a lightly mottled textile texture. With a high sound absorption value, SilentDirect PES Ceiling offers a long-term and effective solution for anyone looking to improve acoustics in a discreet, sustainable, and professional manner.

Installation Options

SilentDirect PES Ceiling offers several installation options to suit different types of ceilings, environments, and installation requirements.

Without mounting accessories
This option means that no mounting hardware is included, giving you complete freedom to use your own fasteners such as adhesive, screws, or other solutions tailored to the ceiling’s construction.

With mounting brackets
When installing with mounting brackets, 4 mounting brackets are included for sizes 592x592mm, 800x800mm, and 1000x1000mm, and 6 mounting brackets are included for other sizes. Choose between mounting brackets – 0 mm spacing for ceiling-close mounting or mounting brackets – 50 mm spacing, which creates a 50 mm air gap for increased sound absorption.

With wire suspension
When selecting wire suspension, the following is included a wire kit designed for stable suspension. Each kit contains a coil spring, a wire with an eye, and a carabiner with an adjustable clamp. Hooks for ceiling mounting are not included and must be selected based on the specific ceiling structure.

What is the difference between mounting brackets – 0 mm spacing – and mounting brackets – 50 mm spacing?

Mounting brackets – 0 mm spacing mount the absorber directly against the ceiling without an air gap, creating a discreet, flush-with-the-ceiling look where the sound absorber protrudes approximately 50 mm, corresponding to its thickness.

Mounting brackets – 50 mm spacing, on the other hand, create an air gap of approximately 50 mm between the sound absorber and the ceiling, resulting in a total projection of approximately 100 mm. The air gap improves sound absorption and is recommended in spaces with high ceilings or where maximum acoustic performance is desired.

The choice between mounting brackets – 0 mm gap and mounting brackets – 50 mm gap is therefore a matter of balancing aesthetics and sound absorption. For the best acoustic results, gap brackets are recommended, while gapless brackets are an excellent alternative when a more discreet appearance is desired.
