Protecting The Mounting Wall With Astud Wall - Spartherm Premium V-FD-87h Aufbauanleitung

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 Ger-
man Institute of Building Technology in Berlin (DIBt). It has to be installed
according 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
provided by the insulation material manufacturer.
Some thermal insulation materials can be used as a protective 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 abra-
sion 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 installa-
tion 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 wall must be constructed when installing a wall-mounted
fireplace system. The stud wall must protrude at least 20 cm above the
connecting piece?
• A protective 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
• Protective walls are normally of brick construction, but may also be
constructed from the heat-insulating panels referred to above, in order
to reduce the total thickness of the protective wall and insulating
material.
8 Insulation of the heating chamber using, e.g., dimensionally stable mineral wool according to the heat
insulation thickness technical data.
23 Stud wall, 10 cm thick*
* If necessary, use a substitute insulation material (e.g. calcium silicate) in the place of front-mounted
masonry and insulation (point 8), in accordance with the technical data provided by the manufacturer.
