Impact sound insulation
Impact sound insulation for stairs
Impact sound is an undesirable and specific type of sound transmission. Especially in staircases of apartment buildings, inadequate impact sound protection can lead to annoying disturbances. To solve this problem, monolithic stair elements can be acoustically separated from adjacent building components with the Halfen sound insulation system. Halfen impact sound insulation products are perfectly qualified to meet the requirements for impact sound reduction.
Campi di applicazione
- HBB - Impact sound insulation box for acoustic decoupling of the landing
- HTF-T - Impact sound insulation element for acoustic decoupling of a flight of stairs
- HTPL - Impact sound insulation plate for lateral decoupling of a flight of stairs and the wall of the staircase
- HTF-B - Impact sound insulation element and CRET-TS SET impact sound insulation dowel for acoustic decoupling of precast concrete stairs and the floor slab
- HTT - Impact sound insulation element for decoupling of a precast or in-situ poured staircase, to an in-situ cast concrete
Gamma di prodotti
HBB
Decoupling of the landing slab
HBB Impact sound insulation box for installation of on-site or precast concrete landing slabs
The Halfen impact sound insulation box is used as a point support for the landing slab. The load is transferred via high-quality elastomeric bearings. The elements can be installed in in-situ concrete as well as in prefabricated landing slabs, at the connection with concrete or masonry walls.
HTF Isolamento dal rumore da impatto
Acoustic decoupling of a precast stair element
HTF-T Impact sound insulation element for placement of a precast stair flight on a corbel foreseen in a landing slab.
Halfen HTF-T impact sound insulation elements are suitable for supporting prefabricated stair flights on in-situ poured or precast landings. The load is transferred through profiled elastomeric bearings. The impact sound insulation is located between the landing and the flight of stairs.
HTF-B
HTF-B Impact insulation element for acoustic decoupling between precast concrete stairs and the supporting slab.
CRET-TS SET
CRET-TS SET impact sound insulation dowel is positionned vertically in the joint between the bearing slab and the first step of the staircase, securing the staircase in the right position, while guaranteeing the impact sound insulation provided by the HTF-B impact sound insulation mat.
HTPL
HTPL Impact sound insulation for lateral edge decoupling of a flight of stairs and a staircase wall
Acoustic decoupling of an on-site cast stair staircase
Acoustic decoupling of an on-site cast stair staircase
HTT Impact sound insulation element for connection of an in-situ concrete or precast staircase to an in-situ concrete landing-slab
Halfen HTT Impact sound insulation elements are suitable for on-site and precast concrete staircases to on-site cast landing-slabs with predominantly static loads. The HTT Elements transfer vertical and horizontal loads.
