• The film is mounted in freely accessible places where the radiation of heat is not prevented by cupboards, partition
walls etc.
• All electric and mechanical installations which are passing through the ceiling, like electric cables, pipes, chimneys
etc. must be completed before the installation of the heating film.
• The heating film must be laid in close contact between the thermal insulation and the plasterboard panel. The heating
film doesn't fulfill the function of a vapor barrier. The vapor barrier (PE foil) must be placed under the heating film.
• The ceiling construction in which the heating film is installed must be constructed as the floating type, without a
firm connection with the peripheral walls. Possible elements which will cover the joint between the horizontal and
vertical construction (e.g. styrofoam corner profiles) can only be attached to the vertical surface.
• The surface of the ceiling (what is known as the dilatation complex) must not be longer than 8 m and larger than
50 m 2 . If the surface of the ceiling exceeds the prescribed dimensions, a dilatation joint is necessary. The dilatation
joint doesn't need to divide the surface in half; we recommend that it is located in a suitable place (a gap, corner,
change in the shape or cross section of the surface) in such a way that none of the surfaces exceeds the prescribed
dimensions. The elements which cover the dilatation joint can be attached to only one of the surfaces which are
divided by the dilatation joint. If the ceiling deflection is higher than 10 mm, a detail of the connection of the
suspended ceiling to the wall needs to be selected with which the suspended ceiling is not attached to the wall.
• All the joints between the boards (both transverse and vertical) must be bonded and reinforced with strengthening
glass tape (except the dilatation joints).
• After the bonding and completion of all wet processes on the plasterboard panels, it is necessary to adhere to all
the technical procedures regarding the maturing and drying of these materials. The subsequent bringing of the
heating film into operation must be carried out with a gradual build-up of the temperature in the room. The
temperature build-up is controlled by a room thermostat with the help of which the temperature of the room is
increased by 1 °C per day to the required value. The starting temperature of the temperature build-up is the lowest
temperature in the room which is achieved during the day without heating (the heating and change of temperature
is started in the hours of morning).
• If possible, the heating film should be brought into operation before pointing and bonding. In this case, it is not
necessary to carry out the temperature build-up as described in the previous point. Both the panels and the
surrounding environment will get dry, and the risk of the subsequent cracking of joints decreases. The bonding and
pointing is carried out subsequently, within 24 hours after the operational temperature of the room has been
achieved.
• Heating foils must not be installed in close proximity to aluminium foils, foils containing metals or on constructions
with high humidity.
2. Checking and preparation of the ceiling area for the installation of ECOFILM C
• The spacing of the ceiling construction must be in accordance with the installation instructions of the producer and
according to the size of the heating film.
• The heating film must not be laid in such a way that the heating part of the film or the copper conductor bus bars
overlap or are in contact with the ceiling load-bearing beams.
• Flammable materials need to be removed from the interior ceiling space, or they need to be replaced by non-
flammable ones. The load-bearing beams for the attachment of the foil may also be made of wood. All installations
passing through the interior ceiling space should be checked against the relevant building documentation.
3. Installation
• Installation can be done from above or from below, depending on the accessibility of the ceiling area.
• Attach the heating film in the corner which is formed by the load-bearing beams (cross beams) of the ceiling
construction using nails or clips and unwind about 1 m of the film's length. After unrolling, the film should be
stretched, straightened, and to prevent it from being crumpled later, fastened along the longitudinal sides along the
non-heating edges and further every approx. 40 cm with nails or clips to the ceiling construction.
• If steel load-bearing beams are used, the heating film is attached to them either with double-sided adhesive tape or
with screws with countersunk heads. The installation of the whole strip of film, and subsequently of other strips of
the heating film, takes place in a similar manner. Conductors which pass through the steel construction must be
