Floating floors are used to resist the transmission of sound or vibration between noisy and quiet ambiance. Two masses separated by a low-frequency response isolator create an environment for noise and impact reduction many times greater than a single mass of equal weight. First Technical Services Floating floor Suitable for both new build and refurbishment projects, these acoustic solutions are available in a range of Combinations and system depths and offer extremely high standards of acoustic control.
Floating floor systems are used for many purposes, mainly to resist noise passing through the floor but also to isolate against vibration and impact.
Acoustic: floating floors are used to resist the transmission of sound or vibration between noisy and quiet ambiance.
Two masses separated by a low-frequency response isolator create an environment for noise and impact reduction many times greater than a single mass of equal weight. The isolator seeks to emulate the stiffness properties of the air, but as this space increases the frequency of the isolator governs the frequency of the floor system. If noise reduction is the primary goal then enveloping walls usually rest on the isolated floor. Ceilings with their own isolator caps the constructions. If the frequency range is above 20 Hz. Neoprene is generally the best choice. if vibrations or impact reduction is required., springs supporting the isolated floor by themselves will normally suffice. The professional acoustician is the best person to make these evaluations. Thirty years ago several manufacturers working with Riverbank acoustical laborarities tested an isolated room under ideal conditions. Much of what was learned for attenuating high-frequency noise (above 20hz) had long been practiced by First Technical Service.
Concrete floating floors consist of a reinforced concrete layer, supported by rubber plugs isolators. These floors typically use a jack-up system to raise the concrete floor as this offers a number of constructions and acoustic benefits. Concrete floating floors are stable and, due to high mass, offer the best possible isolation performance. Rubber is the correct choice when isolating against airborne noise and impact.
MOST IMPORTANTLY, ONCE THE ABOVE CRITERIA IS ESTABLISHED, it is the ISOLATER’S NATURAL FREQUENCY WITH DYNAMIC STIFFNESS RESPONSE AND ITS CONTINUING LONGEVITY THAT WILL EFFECT THESTC/&IIC (IMPACTINSULATION CLASS ) OF A PROTECTED SPACE!
Natural frequency establishes the response from one slab to the other. For the Control of high-frequency noise, 10Hz is the established criteria including dynamic stiffness procedures are critical as is ongoing verification of quality control. Long test histories have shown that 2” of airspace should not be diminished.
Such systems are custom designed, thereby permitting a high degree of flexibility with regard to both ergonomics and aesthetics, whilst, achieving a careful balance between technical excellence and economy. First Technical Service is fully equipped and supervising the installation of high-quality speech reinforcement systems for churches and cathedrals of particular interest is the range of loudspeakers, designed to direct high-quality sound down to the congregating without the need to angle the loudspeakers away from the supporting wall or column. Combining technical ingenuity with functional designs ensures an unobtrusive appearance, which can be of great importance in avoiding the disruption of architectural lines within churches and cathedrals.
This application is suitable in locations more suited to a product where long-term adhesion to the subfloor is not possible. The Floating Floor system is ideal for a range of smooth and rough subfloors and is easily self-installed in a matter of minutes, eliminating the need for any lengthy installation.
Suitable for both new building and refurbishment projects, these acoustics solutions are available in a range of combinations and system depths and offer extremely high standards of acoustic control.
The innovative cradle and batten systems also offer the ability to be leveled on-site to eliminate variations in the structural floor surface and provide access for service.
