Protecting The Mounting Wall With Astud Wall - Spartherm Mini R1V51 Installation Instructions Manual

Mats, sheets or shells of silica-based insulation material (stone or slag and
ceramic fibres) of material class A1 as per DIN 4102, part 1 with an upper
application limit temperature of at least 700°C when measured as per DIN
52271 and a rated gross density of 80 kg/m3 are to be used to produce
the insulating layers (see Special information on insulation of the mounting
wall/side wall). When using insulating materials of this type, ensure they are
provided with an AGI-Q 132 code number.
The code number of the insulating material used must not, however, contain
the code sequence "99"! Where the insulating layer is not held in place by
walls, cladding or plating, it should be pinned into position at a maximum
distance of 33 cm between the pins. Other insulation materials, e.g., gas
concrete or mineral construction materials, must be approved by the German
Institute of Building Technology in Berlin (DIBt). It has to be installed accord-
ing to the manufacturer's instructions.
The individual insulation materials have different coefficients of thermal
conductivity which means the insulation material thicknesses will vary. The
required insulation material thickness can be taken from the diagram pro-
vided by the insulation material manufacturer.
Some thermal insulation materials can be used as a stud wall and insula-
tion at one and the same time. This significantly reduces installation depth.
Thermal insulation made of non-abrasive material such as, e.g., stone and
slag fibre must be abrasion-resistant, e.g., with steel plate cladding, so
that the recirculating air does not transport insulation particles into the
room. Other thermal insulation sheets leave the factory with added abrasion
resistance as required. This type of insulation material may only be installed
offset and all joints must be sealed. Where multiple insulation layers are
required, the joints should be arranged to overlap. The installation must
be correct and abrasion-resistant. Moreover, the exact position must be
permanently ensured.
5.4.2 PROTECTING THE MOUNTING WALL WITH A
STUD WALL
• A protective stud wall must be constructed when installing a wall-
mounted fireplace system. The stud wall must protrude at least 20 cm
beyond the connecting piece.
• A stud wall is not needed, where the walls of the building are:
- at least 11.5 cm thick
- made from non-combustible components
- is not a bearing concrete or reinforced concrete wall
• Stud walls are normally of brick construction, but may also be con-
structed from the heat-insulating panels referred to above, in order to
reduce the total thickness of the stud wall and insulating material.
