Acoustic Subfloors

Our acoustic subfloor systems are quick to install and easily levelled onsite. They are installed all over the world.

100% recycled, 100% effective

Our acoustic subfloors are available as two different systems. Each is designed for different applications.

InstaCradle is our specialised acoustic subfloor for commercial gyms, and EcoCradle is our acoustic system for use with outside decking. Easy to install and proven to reduce sound impact, both systems support reduced environmental impact through using recycled materials.

Our acoustic subfloors are an effective solution for gyms and exercise spaces that share buildings with residential, business and retail units. See some of our case studies.

How does InstaCradle work?

Our acoustic subfloors for commercial gyms and health clubs provide a cost-effective solution for isolating the low frequency noise of exercise environments. InstaCradle is designed to reduce both impact and airborne sound, and will absorb the impact shocks of free weights.

InstaCradle systems are quick to install. There’s no need for concrete screeds, and no waiting for additional contractors or drying times. The rubber cradles are loose laid and do not require fixing to the subfloor. Any issues with uneven floor surfaces can be tackled easily and accurately onsite with interlocking cradle packers.

Our acoustic subfloors for gyms are tried and tested for effectively reducing the airborne and impact sound caused by exercise equipment and work-outs. InstaCradle is the ideal solution for commercial gyms that operate alongside workspaces and residential settings.
