Vibratec's flexible floor bracket VT-FFB for constructing elastic, floating floors, in markets where timber joists are 45 mm in thickness. This bracket comes in two versions depending on the size of your floor joists.

Flexible Floor Bracket VT-FFB

Vibratec’s Flexible Floor Bracket is a quick and easy way to build an adjustable floating floor. The bracket fits on standard timber joists (45 mm width) and is fastened with screws. The height can be adjusted about 30 mm and the total height of the floor depends on the height of the joists. By sewing steel wire through the holes on the side of the foot you can make a web to put insulation on.

Product Characteristics

Impact sounds are greatly reduced by building a floating floor. The Flexible Floor Bracket VT-FFB is an impact and step-sound isolating product and comes as standard with a Regufoam 510+ 25 mm cushion. For most flooring applications this is the perfect choice, however if there are larger loads or demanding applications to take into account, Vibratec should be contacted to make the right material choice.

Optimal load for the standard VT-FFB 510-25 is a dead weight of approximately 15-30 kg/bracket and a total load (dead load + live load) of maximum 65 kg/bracket. For housing, offices, music studios with 2 layers of chipboard, beams are placed cc600 and elastic brackets cc600.

Resonance frequency of the system is depending on the load, in the example above, about 12 Hz and 3 mm deflection is achieved. The stiffness can be adjusted by playing on the number of isolators per m2 and/or by choosing softer/stiffer material for the isolators.

Product Applications

Floating floors with vibration isolation to eliminate impact sounds. Works for new builds and also perfect for renovations where the old floor is uneven.

Step-sound isolating floors are floating floors with vibration isolating elements to eliminate impact sounds that resonate through the structure of the building.
