TPS-CD impact sound insulation construction

Profile and fastening system to improve the footfall sound insulation mainly of wooden beam ceiling constructions in prefabricated houses, wooden skeleton constructions and in the renovation of old buildings. Construction height 25 mm, adjustable, for planking with plasterboard or gypsum fiber boards.

Description and installation instructions

In general, before installing the TPS-25, the general processing instructions for wood components (see below) must be observed. The profiles are divided into mounting distances of ≤ 500 mm depending on the type of planking. The beam spacing should not exceed 700 mm. In the case of larger beam spacings, the centre distances of the TPS-CD profiles must be reduced according to the loads. At the wall connection, the U-connection profile No. 5312 can be provided as an installation aid.

The TPS-CD profile No. 5104 is always mounted crosswise to the beams. For this purpose, the required number of TPS spring clips No. 6126 is clipped into the profile and screwed to each wooden beam together with two pieces of the enclosed wood screws. The maximum permissible load of 0.08 KN (8 kg) per spring clip must be observed.

Profile joints must be made using TPS longitudinal connectors No. 6127, but must be avoided in the middle of the field and also several times next to each other. Profile cuts must be made cleanly to avoid cutting the profile ends open. If necessary, the profile ends must be pressed together. Then screw on the planking crosswise to the TPS CD profiles using the drywall screws corresponding to the thickness of the planking. Contact between the drywall screws and the clips must be avoided, as must contact with the upper edges of the profile. During the planking process, it is recommended to continuously check the ceiling surfaces for possible noise and to make any necessary improvements.

The planking connections to the adjoining components must be professionally executed with suitable joint sealants. Alternatively, we recommend tacking and filling the PVC expansion joint profile No. 3750 over the corner on the ceiling or wall planking.

Adjustment

After screwing on the TPS spring clip, bend both vertical lugs against the screw heads with a hammer blow. Then both screws can be turned back, whereby the TPS spring clip also moves downwards. The maximum adjustment travel for the supplied 4.2 x 35 mm wood screws is ≤ 5 mm. Larger unevenness requires prior assembly of a basic construction of boards, wooden slats 

 or beam levelling angles (Art. No. 5569). It is generally recommended to secure the TPS clip against noise after adjustment, e.g. by backing it with suitable material.

General remarks

When planning and installing ceiling linings, sloping roof linings or suspended ceilings on new or when renovating old wooden components/wood beams, the following instructions must be observed:

• Wooden components/wooden beams/wooden girders can bend, twist (sometimes yield) due to equal and uneven loading, e.g. snow load (roof), wind suction or pressure, furniture, walking on by users/residents, heavy floor constructions.
• The mentioned movements in the wooden construction can be statically and/or dynamically introduced and transferred into the secondary construction (ceiling linings, suspended ceilings), which can lead to the rubbing of metal parts of the substructure against each other and to the deformation of the substructure in connection with noise generation.
• Appropriate measures include Transverse bracing of the primary wooden structure using suitable aids (wooden or metal bracing in conjunction with appropriate fasteners), strengthening of the primary wooden structure using additional beams, installation/assembly of suspended ceilings or cladding only after completion of load-introducing new heavy flooring on buildings, non-positive attachment of suspension systems directly to the wooden beams in the context of renovation work; any remaining old ceilings may have to be cut out at certain points for this purpose, formation of sliding connections to adjacent components in order to avoid constraint.
• No liability can be assumed for the functioning and interaction of primary and secondary structures.
