Heat Insulating Material
Prowolf Heat Insulating Bricks
For heat insulation of extension walls when mounting chimneys in accordance with DIN 18895
Part 1, and also for tiled stoves in accordance with the Specialist Regulations for the Tiled Stove
and Air Heating Construction Trade.
Heat insulating bricks based on the raw materials of calcium silicate and aluminium silicate.
Prowolf heat insulating bricks must be processed with the appropriate DIDOTECT 135-V
fireproof glue.
The Prowolf heat insulation can be heat insulation and brick lining at the same time, see
Diagram 1.
Simple machining of heat insulating bricks with e.g. a gas concrete saw.
Prowolf heat insulating bricks are wear-resistant, additional protection is not statutorily
required. It is possible to seal the surface with DIDOTECT 135-V fireproof glue, however
only for thicknesses of up to 1mm. The glue layer must be sufficiently hardened (a week at
80°C)

Technical Data and Diagrams on Reverse Side
Prowolf bricks are glued together using DIDOTECT 135-V fireproof glue; both the glue and the
yet fresh brickwork should be protected from frost. The glue should be stirred well before being
applied. Any fluid discharged from above may not be drained; it must instead be stirred in. You
should ensure that the glue does not come into contact with the technician’s eyes, skin, etc. In
the event of work stoppages, the glue container should be closed well so as to prevent the
surface from drying out. The glue can be adapted on a small scale by adding water in order to
obtain the desired processing consistency. The bricks to be processed should be dry and only
be slightly humid. Prowolf bricks must be free from dust or other adherences. As a rule, the glue
should be applied to one side of the surfaces to be glued. The glued joint should be 2 – 3 mm
thick; the optimal thickness for the glued joint is two millimetres. The glue drying time is approx.
12 to 48 hours depending on the ambient temperature. Preparation containers and tools should
be cleaned in due time and with care.
General pre-requisites for the assembly of Prowolf bricks in front of walls to be protected are: a
sufficiently adhesive surface for glueing the bricks onto the wall to be protected. It must be level
– unevennesses of up to 4 millimetres can be evened out by the glue on small surfaces – it
must also be statically stable. When glueing onto the wall to be protected, it is recommended to
coat both sides of the surfaces to be glued with DIDOTECT 135-V. The Prowolf bricks must be
screwed together with gypsum plasterboards. They are countersunk 2cm-deep into the Prowolf
bricks in order to avoid too strong thermal bridges or to protect the screw heads. The remaining
recesses are sealed with fibre mortar WT. This type of fastening can only be used for Prowolf
bricks of at least 64mm in thickness; it is only then that a sufficient remaining minimum Prowolf
brick thickness of approx. 40mm between the surface of the gypsum plasterboard and the
screw head can be guaranteed.

Diagram 1
Working diagram for determining the layer
thickness of “Prowolf“ heat insulating bricks
for use in accordance with DIN 18895-1, as
a replacement for brick lining (BL) and heat
insulation (HI) for inflammable and / or
statically loaded installation walls.
Example:
Necessary heat insulation (HI) in accordance
with manufacturer’s specifications: 10cm
Necessary brick lining in accordance with
DIN 18 895-1, Section 5.6.2.4: 10cm
Total thickness in accordance with DIN 18
895-1, Sections 5.6.2.3 and 5.6.2.4: 20cm
corresponds to 12cm “Prowolf” heat
insulating bricks.

for use in accordance with DIN 18 895-1, as
a replacement for heat insulation (HI) for
non-combustible and/or unstatically loaded
installation walls.
Example:
Necessary heat insulation: 7.0cm
corresponds to 8.0cm “Prowolf” heat
insulating bricks.
