Application

  • Used in housing, apartments, laboratories, gyms/sports halls and offices.
  • Can be assembled on any base with any floor covering desired.

Renovation with SubFloor:

  • Used levelling uneven floors, raising the floor a step height or allowing for installations under the floor.

In situ cast SubFloors:

  • With the SubFloor system, flooring can be cast thinner. Approximately a cast flooring of 300 mm can be reduced to 200 mm and the sound insulation maintained or improved. This generates a lighter overall construction with an improved economy. The installation space created also allows for adjustments and future renovation.
  • Simple floor levelling with off-site prefabricated bathrooms.
  • Commonly installed on hollow core slabs when the objective is to attain sound class A or B for dwellings without additional coverings.

Description

SubFloor Acoustic creates a precision raised floor ranging from 35 to 414 mm in height, providing an ideal space for installations and insulation.

This advanced flooring system consists of wooden joists, screws, and acoustic feet. The sizes and materials of the joists and screws can be adjusted based on specific requirements. Typically, chipboard flooring is used on top, allowing for a wide range of flooring materials.

To meet acoustic requirements, the standard feet are replaced with our unique acoustic feet. Aside from this, the design remains identical to the simple SubFloor system. The acoustic feet feature dual-action dampening that reduces impact sound by up to 28 dB without compromising stability and can be used with either wooden or steel joists.

Features and Benefits:

  • Superior Acoustic Damping: Reduces impact noise by up to 28 dB with SubFloor Acoustic Feet 12 or 25, enhancing overall sound insulation.
  • Comprehensive Noise Reduction: Mitigates impact noise, rebound noise, flanking transmission, and airborne noise when used with insulation.
  • Dry, Fast Installation: Can be assembled, installed and finished quickly without the need for wet surface levelling, chemical additives, or long drying times.
  • Flexible Installation Routing: Ample space between the surface flooring and SubFloor for easy routing.
  • Lightweight Construction: Weighs between 2.02 kg/m² and 11.15 kg/m².
  • Precision and Adjustability: Ensures high accuracy and adjustability with quality materials.
  • High Load Tolerance: Complies with EKS (European Construction Standards) for robust performance.
  • Versatile Height Options: Provides precision raised floors from 35 to 414 mm, with the potential for even higher flooring if needed.
