Noise can be annoying, make it Whisper

Exceptional Noise Absorption

Stratocell® Whisper® acoustic foam delivers industry-leading sound absorption with an NRC rating of 1.00—the highest possible according to the ASTM C423 standardized test. This means it absorbs 100% of sound in standard testing conditions, ensuring optimal noise control.

Waterproof & Moisture Resistant

Unlike traditional acoustic foams with open-cell structures that absorb moisture, Stratocell® Whisper® features a closed-cell design. It resists water while preventing sound reverberation, making it waterproof, washable, and highly effective in damp environments.

Built for Tough Environments

Independently tested to EN 14388 standards, Stratocell® Whisper® acoustic foam offers over 50 years of outdoor durability. It withstands exposure to water, moisture, dirt, dust, UV light, chlorine, and harsh chemicals, making it perfect for demanding applications.

Fibre-Free & Safe

Stratocell® Whisper® acoustic foam is fibre-free, meaning no crumbling, irritating dust, or corrosive gases. It resists dust adhesion, is washable, and remains safe for use with common household cleaning products.

Stratocell® Whisper® foam is specifically made to absorb noise indoors and outdoors. Manufactured unlike any other foam, Stratocell® Whisper® is a closed cell foam with very large cells that are punctured with thousands of pin holes. Sound can no longer reverberate from or into the area the foam has been installed.

What is Whisper foam used for?

Sound Absorption

Sound absorption is essential when the source and receiver are in the same room, a common use for acoustic foam. Stratocell® Whisper® reduces reverberation, ensuring high-quality sound for recording studios, theatres, restaurants, and sporting facilities.

Transmission Loss (Sound Proofing)

Transmission loss measures the reduction in decibels when noise is prevented from escaping a room. Stratocell® Whisper® excels in projects requiring noise control, including construction, transport, manufacturing, and industrial applications.

Transport, Rail & Roads

Stratocell® Whisper® is ideal for transit barriers, walls, and tunnels, blocking sound from sensitive areas. Its lightweight design simplifies installation, saving time and effort. Integrating this acoustic foam into construction projects minimizes sound reverberation and transmission.

Sports Facilities

Vertical hanging baffles made from Stratocell® Whisper® are perfect for sports facilities and pools. Exposing both sides of the foam maximizes its sound-absorbing properties. Refer to the product brochure for sound absorption data and baffle installation guides.

Factories, Engines, Machinery

Stratocell® Whisper® acoustic foam effectively reduces noise from generators, AC enclosures, machine rooms, and engine bays. Its flame-retardant variant, Stratocell® Whisper® FR, withstands air temperatures up to 90°C, ensuring safety and performance.

Commercial Spaces

In commercial spaces like bars and restaurants, limited ceiling height can amplify noise, disrupting the guest experience. Ceiling-mounted Stratocell® Whisper® foam rafts absorb sound while enhancing the space’s visual appeal. Adjusting the void distance (space between the ceiling and foam) optimizes sound absorption across various frequencies.

Sound Absorption Coefficients

Sound Absorption Coefficient (α) (Internal Sound Absorption): This measures how much sound is absorbed by a material compared to how much hits it at a specific frequency. It ranges from 0 (no absorption) to 1 (total absorption). A Sound Absorption Coefficient (α) of 1 represents 100% absorption.
