Freedom Step® Subfloor System for acoustic and sprung floor applications.
Freedom Step® Layout Subfloor System serves a wide variety of applications where the absorption of impact and sound isolation are required. Freedom Step® Subfloor System and Freedom Step® Pro Subfloor are an engineered floating floor system that allows multi-use buildings to function by mitigating structure borne sound transfer. Floor impact isolation is required for applications such as ‘free weight drop’ and ‘treadmill noise’ in health clubs, ‘heavy floor impact’ for activities such as ‘dance studios’, ‘martial arts’, or ‘aerobics classes’. The Freedom Step Layout Subfloor is a ‘low cost’ and high performance system that provides the highest acoustic impact isolation.
Freedom Step® Layout Subfloor System is extremely fast and easy to install. It is ready to be installed right off the skid and does not require any special tools or training. The System is comprised of Pre-Punched Fiberglass blanks and Freedom Step Pyramid rubber isolators. Nominal 1” thick for Regular and 2” thick for Pro. The rubber isolators are simply dropped into the precut voids and then two Layers of plywood are installed on top with staggered seams. For dance floors use a ‘good one side’ ½” plywood to retain the maximum resilience. For commercial gyms use minimum 5/8” or ¾” plywood before the gym floor finish for impact resistance. Concrete toppings can be poured over Freedom Step – Please consult factory for loadings. Freedom Step® Layout Subfloor System has the highest acoustic isolation available of any floating floor in the world. Key to its performance are the ‘Pyramid shaped isolators’ that consist of Pyramidal and domed multi pointed ‘compressible elastomer’ absorption pads. These are simply dropped into the pre-punched acoustic media and finished with customer supplied double layer of plywood.
Acoustic performance is measured in an ASTM recognized testing method for IIC (Impact Isolation Class). The improvement is reported as Delta IIC. Lab Tested on a 6” concrete slab the Freedom Step System has the following acoustic performance.
Freedom Step® Layout Subfloor Regular nominal 1” overall thickness – up to Delta 35 improvement
Freedom Step® Pro Layout Subfloor – nominal 2” overall thickness – up to Delta 44 improvement with significant low frequency benefits.
