The document describes the 6-step process for applying an external thermal insulation system from ISOMAT. The key steps include: 1) attaching an aluminum holding rail around the building, 2) applying adhesive to insulation boards, 3) attaching the insulation boards in overlapping layers, 4) mechanically fastening the boards with anchors, 5) applying a base coat of adhesive with mesh reinforcement, and 6) applying a plaster finish. The system provides energy savings, environmental benefits, and a durable, weather-resistant building facade.

Next the adhesive (ISOMAT AK-T35/T55/T65)
is applied on the thermal insulation boards
(EPS, XPS, MINERAL WOOL) in 2 different
ways:
a) Uniformly, on the whole surface of the
board, using a notched trowel, if the
substrate is smooth.
b) Along the perimeter of the board and in 2
or more spots in its center, using a trowel,
if the substrate is uneven.

The aluminium holding rail is placed around
the building and parallel to the ground by
fastening it on the substrate with special
anchors (2 pieces/meter).
With the external thermal insulation system ISOMAT
THERMOSYSTEM you save energy by consuming less fuel for
heating during winter and less electrical power for airconditioning during summer. Thus, since the energy cost is
significantly reduced, the money invested in the installation of
ISOMAT THERMOSYSTEM is paid off at a great extent already
from the first years of the system's operation.
“I contribute to the environmental protection”
ISOMAT THERMOSYSTEM contributes to the protection of the
environment, as it reduces drastically the air pollution, which is
caused by the use of fuel for a building's heating or cooling.
Particularly, ISOMAT THERMOSYSTEM contributes to the
reduction of emission of carbon dioxide and other pollutants,
such as nitrogen and sulphur oxides, that are responsible for
the creation of the Greenhouse Effect.
The energy saving in buildings is an evergreen
topic, as it leads to the reduction of energy
consumption for heating and cooling, which
reduces radically both the households' expenses
and the air pollution.
The thermal insulation boards (EPS, XPS,
MINERAL WOOL) are then fixed by placing
them from bottom up, in horizontal
consecutive layers overlapping each other so
as to form a layout of crossed joints that will
prevent cracking of the overlaid plaster.
For this reason, ISOMAT has developed the
external thermal insulation system ISOMAT
THERMOSYSTEM, which contributes to great
energy saving by consuming less fuel for heating
during the winter and less electrical power for airconditioning during summer due to the excellent
thermo-insulation of the building. In this way you
save money and contribute to the environmental
protection, while you enjoy thermal comfort in your
living space during the whole year.

“I enjoy my living space”
ISOMAT THERMOSYSTEM eliminates the thermal bridges.
In this way the building remains thermal protected all-around
and ensures a stable as possible room temperature throughout
the year. Thus, you enjoy thermal comfort in your living space
during all seasons.

“I renovate and protect my building”
The following day the thermal insulation
boards (EPS, XPS, MINERAL WOOL) are fixed
mechanically with collar head anchors, which
should have a length according to the
thickness of the board and the type of the
substrate. Next the base coat
(ISOMAT AK-T35/T55/T65) is applied
universally on the boards.
The base coat is applied with a notched
trowel in parts of width > 1m. Afterwards,
the fiberglass mesh is placed and pressed on
the still fresh layer of the base coat with a
smooth trowel.
CERTIFIED SYSTEM
After the base coat has fully dried, the
surface is primed with the primer of the
respective plaster that will be used. After the
primer has dried, the surface is then coated
with the pasty acrylic or silicone plasters
MARMOCRYL of ISOMAT.

ISOMAT THERMOSYSTEM has been
certified according to the requirements of
the European Standard EN 13499:
external thermal insulation composite
systems (ETICS) based on expanded
polystyrene.
This certification guarantees that the
system maintains a stable, long-term
performance.
ISOMAT THERMOSYSTEM constitutes a great solution for the
renovation of old constructions. The buildings acquire a new,
beautiful decorated façade thanks to the colored, high quality,
pasty plasters MARMOCRYL of ISOMAT, which are available in
305 unique colors. At the same time, the façade becomes
absolute weather resistant and waterproof, without losing its
vapor permeability.
“I finish work fast & easy”
ISOMAT THERMOSYSTEM is applied fast and easy. Its fast and
most cost-effective installation is assured only if it is done by a
trained installation crew. During the application of ISOMAT
THERMOSYSTEM, the tenants do not need to move out from
the house, while there is only a minimum disturbance for the
neighbours.
