Thermal Insulation Material Thickness - Spartherm Mini R1V 51 Notice D'utilisation

5.4.1. THERMAL INSULATION MATERIAL THICKNESS

For information on the thermal insulation material thickness relevant
to your fireplace insert, see „Technical Data" on page 17.
Use mats, sheets or shells of silica-based insulation material (stone
or slag wool and ceramic fibers) in construction 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
3
density of 80 kg/m to produce the insulating layers. They need to
have a corresponding insulation material code as per AGI-Q 132.
The insulation material code may not contain the number sequen-
ce „99". If this insulating layer is not framed by walls, facing or
adjacent sheets, use fasteners at a maximum distance of 33 cm
to each other. Other insulation material, e.g. gas concrete or mi-
neral construction materials, have to possess a general construc-
tion inspection permit from the German Institute of Construction
Technology Berlin (DIBt). It has to be installed according to the
manufacturer's instructions.
The other insulation materials all possess different heat transfer
coefficients, so insulation material thickness will vary. The required
insulation material thickness can be determined from the diagram
provided by the insulation material manufacturer.
Some thermal insulation materials can be used as a stud wall and
insulation at the same time. This reduces the installation depth si-
gnificantly. Thermal insulation made of stone and slag wool require
abrasion-resistant cladding so the circulation air volume flow does
not transport insulation particles into the room. Other thermal in-
sulation sheets leave the factory with added abrasion resistance as
required. This insulation material may only be fastened with offset
joints and end to end. If several layers are to be fastened, the edges
have to overlap.
