The Knauf TP 115 partition wall insulation board is a non-combustible glass wool insulation board with ECOSE® Technology for sound and thermal insulation of partition walls and walls in drywall construction. With a thermal conductivity of 0.038 W/(m·K) and a fire rating of A1, it provides thermal, acoustic, and fire protection in interior construction, according to Knauf. One package contains 9.43 m² of boards in the format 1250 × 625 mm.
The panel is aimed at drywallers, interior fitters and renovators who insulate stud walls with gypsum plasterboard; suitable components can be found in the categories drywall profiles and gypsum board .
Typical uses and points to check before ordering:
One panel covers heat, sound and fire protection in interior construction; as a non-combustible building material of class A1, the insulation material does not contribute to the fire.
The decisive factors are the panel thickness, stud width, and the sound and fire protection requirements for the wall.
Knauf offers TP 115 in thicknesses from 40 to 100 mm; the design value of the thermal resistance ranges accordingly from 1.05 to 2.63 (m²·K)/W.
The linear flow resistance is at least 5 kPa·s/m² (AFr5); fire resistance classes only result from the tested wall system.
The panels fill the cavity between the studs; the manufacturer's processing guidelines as well as the relevant standards and recognized rules of technology apply. The panel is intended for interior finishing.
The most important parameters according to the Knauf Insulation product data sheet; the thermal resistance depends on the panel thickness.
