Ceiling construction: According to the European guidelines, KIELSTEG ceilings with classical floor structure fulfill all the sound proofing requirements for residential and similar usage with proper area dimensions and avoiding flank transmissions.

Sound insulation: Standard floor constructions with 6 cm loose fill, dynamic soft damping [TP 35/30] and 6 cm screed achieve an impact sound pressure level of L’nT.w= 47 dB.

Installations: The air chambers in the KIELSTEGelements provide a comfortable installation layer for electrical wiring.

Lightweight roof: The hollow section system offers a high insulation effect which gives the customer a surplus value of an energy efficient roof construction with a comparably small thermal insulation package.

Acoustic emission: With a thermal insulation thickness of 70 mm the element already reaches a weighted apparent sound reduction index of Rw = 50 dB.

Fire protection: Without additional building measures, KIELSTEGelements
reach a fire protection rating of REI 30 up to REI 60.
