SilentStep® - Acoustic Residential Raised Floor System

The AFD SilentStep® System is a pioneering residential acoustic hollow floor solution engineered to minimise both airborne and impact sound transmission while maintaining the feel and stability of a solid floor. Designed with modern construction challenges in mind, SilentStep® provides a reliable, non-combustible alternative to traditional timber or screed-based systems.

Its innovative design enables rapid installation, exceptional acoustic performance, and a low embodied carbon footprint. With void capabilities ranging from 19.5 mm to 1400 mm, SilentStep® offers flexibility for a wide range of residential schemes — from apartments to high-rise developments — while meeting the most stringent fire and acoustic standards.

Key Features & Benefits

First Non-Combustible Residential Acoustic Floor System

• Completely free from timber and combustible components, SilentStep® ensures maximum fire safety compliance for residential projects.

Acoustic Excellence

• Engineered to achieve and exceed UK Building Regulation requirements for both airborne and impact sound insulation.

Quick Installation

• Faster and cleaner to install than traditional cradle-and-batten systems. No drying times compared to wet screed solutions, enabling shorter construction programmes.

Stable, Solid Feel

• Delivers a solid-like walking surface with no squeaking or movement, even over uneven subfloors or large voids.

Precision and Flexibility

• Provides a perfectly level, mess-free hollow floor with the ability to accommodate voids from 19.5 mm up to 1400 mm.

Direct Finish Application

• Final floor finishes can be applied directly to the system, with no need for de-coupling layers.

Fire Safety

• Non-combustible construction provides outstanding fire resistance, ensuring compliance with residential fire safety standards.

Sustainable Design

• Certified with an Environmental Product Declaration (EPD). Manufactured using highly recycled materials with a low embodied carbon footprint, SilentStep® supports sustainability targets for residential developments.

Applications

SilentStep® is designed specifically for residential projects where both acoustic control and non-combustible construction are critical. Typical applications include:

• Multi-residential developments (apartments, flats, student accommodation).
• High-rise residential buildings requiring compliance with enhanced fire safety standards.
• Conversions and refurbishments where uneven subfloors must be overcome.
• Sustainable housing schemes prioritising low embodied carbon materials

Technical Advantages

• Void range: 19.5 mm – 1400 mm.
• Rapid installation reduces programme time.
• Precision levelling ensures consistent finished floor heights.
• Eliminates issues associated with timber (movement, squeaking, combustibility).
• High durability with long service life.

Compliance & Certification

• Exceeds UK Building Regulations for airborne and impact sound transmission.
• Fully non-combustible, aligned with current fire safety legislation for residential construction.
• Independently verified EPD-certified, demonstrating reduced embodied carbon.

Sustainability

SilentStep® has been developed with sustainability at its core:

• Manufactured using high recycled content.
• Lower embodied carbon compared to conventional systems such as wet screed or timber-based floors.
• Certified Environmental Product Declaration (EPD).
• Contributes towards credits in sustainability assessment schemes such as BREEAM and LEED.

Summary

SilentStep® represents the next generation of residential acoustic flooring — a non-combustible, high-performing, low-carbon system that delivers safety, speed, and sustainability without compromise. By combining technical performance with design flexibility, it gives architects, designers, and contractors a robust specification choice for modern housing projects.
