SATE BEYEM TRANSPIRA is an external thermal insulation system for façades that uses MW rock wool as the insulating material, natural hydraulic lime (NHL) as the fixing and rendering mortar, and silicate mortar as a flexible, highly breathable finish with a photocatalytic effect.
- Mineral-based ETICS system.
- Excellent sound insulation.
- Excellent fire resistance. Can be used as a
fire barrier on the façade. - Complies with CTE.
- High breathability.
- Reduces/eliminates the risk of
condensation and mould inside. - Photocatalytic. Reduces environmental
pollution and soiling of the facade.
SATE BEYEM TRANSPIRA is designed for use as external thermal insulation on building walls where the
system requires high breathability. The walls may be masonry (brick, block, etc.) or part of a
renovation project. The system is designed to provide the wall on which it is installed with satisfactory
thermal insulation. This ETICS can be used on vertical walls, in both new builds and refurbishments. It
can also be used on sloping or horizontal surfaces that are not exposed to rainwater. The system
consists of non-load-bearing elements. The system does not directly contribute to the stability of the
wall on which it is installed, but it does contribute to its durability by protecting it from the elements.
The photocatalytic finish provides a decontaminating effect as it promotes the removal of toxic gases
from the atmosphere, helping to prevent the accumulation of dirt on a facade.
Suitable substrates for applying BEYEM TRANSPIRA ETICS are: In new builds:
- Brickwork or ceramic blockwork and thermal clay brickwork.
- Mortar renders.
- Concrete blocks.
- Concrete (treated with a bonding agent such as Beyem Unión
Morteros). In renovation projects: - Mortar render.
- Single-layer cladding.
- Facing brickwork.
- Stonework, mixed walls.
For cases not covered here, please contact the Technical Department.
The substrates mentioned above must be sound, clean and free from paint residues, poorly adhered
parts or substances that may impair adhesion. All substrates must be sufficiently flat and have a
surface with adequate porosity and roughness. The substrate must not have any obvious moisture
problems and, where applicable, must have completed its curing shrinkage, having been allowed to
cure for the required period. Severely deteriorated substrates must be treated by sandblasting or a
similar method until a surface with minimum guarantees of roughness and tensile strength is
achieved. In the event of heat, wind or on highly absorbent substrates, it is advisable to dampen the
substrate and wait for the water film to disappear.
In general, substrates must be sufficiently strong to support the coating (minimum adhesion of 0.15
MPa in a pull-off test).
The permissible tolerances for the bracket are:
| Variable | Situation | Tolerance, mm |
|---|---|---|
| Collapse | Between floors | 20 |
| Total building height | 50 | |
| Axiality | Maximum horizontal distance between the centres of the top and bottom walls |
20 |
| PFlatness | In 1 m | 5 |
| In 10 m | 20 |
Protect surrounding areas.
Stir the contents of the container until the product is thoroughly mixed.
Apply directly with a brush or roller.
As a general rule, it is recommended to apply one coat undiluted; however, if necessary,
up to 10% water may be added.
One coat is usually sufficient. In the event of high absorption, apply a second
coat after 12 hours.
- Do not apply Beyem Bioterm at temperatures below 5°C or above 30°C.
- Do not apply Beyem Silicate Primer, Beyem Silicate or Beyem Silicate NOx at temperatures below
5°C or above 35°C, or when the relative humidity exceeds 85%. - Do not apply the system to horizontal or sloping surfaces with an angle of inclination of less than 45°.
- Do not apply if there is a risk of frost, rain or strong winds.
- Avoid direct sunlight during the application of Beyem Bioterm, Beyem Silicate Primer, Beyem
Silicate or Beyem Silicate Nox. - During installation of the system, it is advisable to protect the façade using protective tarpaulins
placed on the scaffolding. It is particularly important to protect the upper part of the façade to
prevent water ingress between the substrate and the insulation panel, both during and after
installation. - Take account of existing expansion joints on the façade and incorporate expansion joint profiles
where necessary. Check the layout of the cutting patterns, if necessary. - The curing time for substrates in new builds must be at least 1 month for ceramic brickwork and 2
months for concrete blockwork. - It is essential to use compatible materials and components recommended and supplied by Rodacal
Beyem to guarantee the quality of the system. - Mineral wool must be protected from rain during installation and until the final cladding is in place.
- The work must be carried out by qualified personnel, with appropriate advice and supervision.
- Read the product Technical Data Sheets carefully.

BEYEM SILICATE PRIMER is supplied in 13-litre containers.
Storage: Up to 12 months in the original, tightly sealed container, at temperatures
between 5°C and 30°C and in a sheltered location. Avoid exposing the container to temperatures
close to 0°C or to direct sunlight.
Tools and equipment can be easily cleaned with water before Beyem Bioterm, Beyem Silicate Primer, Beyem Silicate or Beyem Silicate NOx have set or dried. Once cured or set, the product can only be removed by mechanical means.
The façade finish will be achieved using the BEYEM TRANSPIRA ETICS system, comprising: rock wool
boards in accordance with UNE-EN 13162, with a thermal conductivity of 0.035 W/m·K, Euroclass A1
fire reaction rating and a thickness of . The boards shall be laid horizontally, from bottom to top
and with staggered joints in relation to the previous row. The additional fixing and rendering of the
rock wool boards shall be carried out using Beyem Bioterm polymer-modified, shrinkage-compensated
mortar, covering a minimum of 80% of the bonding surface of the insulation board. The boards shall be
secured using anchor plugs in accordance with EAD 330196-00-0604 at a rate of at least 6 plugs per
m², increasing to at least 8 plugs per m² at heights exceeding 25 m. The insulation boards shall then be
clad with Beyem Bioterm reinforced with 160 g/m² alkali-resistant fibreglass mesh. The coverage shall
be ≈ 1.25–1.75 kg/m² per mm of thickness. The Beyem Silicato or Beyem Silicato NOx finishing coat will
then be applied in the specified colour and textura . The coverage will be approximately
1.80 kg/m². This includes the specific trims required for corners, lintels, changes in plane, expansion
joints, junctions, jambs, coping and other facade elements.
