SATE BEYEM Ecoterm

SATE BEYEM ECOTERM is an external thermal insulation system for facades based on the use of natural materials for all the main components of the system: cork/wood as insulation material (ICB/WF), NHL natural hydraulic lime as fixing and facing mortar, air lime/cork as finishing mortar, including protection mesh (jute).

SATE BEYEM ECOTERM is intended for use as thermal insulation on the outside of building walls. The walls can be made of masonry (brick, block) or natural materials (wood, cork, ….). The system is designed to provide the facing on which it is installed with satisfactory thermal insulation. This SATE/ETICS can be used on vertical surfaces, both in new construction and in renovation. It can also be used on inclined or horizontal surfaces that are not exposed to rainwater. The system consists of non-load-bearing elements. The system does not contribute directly to the stability of the wall on which it is installed, but contributes to its durability by protecting it against natural agents.

The useful substrates for the application of SATE BEYEM ECOTERM, both in new buildings and in refurbishment, are as follows: In new construction:

• Brick or ceramic block masonry and thermo-clay masonry.
• Mortar rendering.
• Concrete block.
• Treated wood.

In refurbishment:

• Mortar rendering.
• Single-layer cladding.
• Facing brickwork.
• Stone masonry, mixed walls.
• Treated wood.

In cases not described consult the Technical Department.

The aforementioned substrates must be sound, clean, free of paint residues, poorly adhered parts or substances that may hinder adhesion. All substrates must have adequate flatness and present a surface of adequate porosity and roughness. The substrate must not have clear problems of dampness and, where applicable, must have completed its curing shrinkage and its maturing period must have been respected. Weak, damaged or deteriorated concrete and, where necessary, sound concrete must be removed by suitable manual or mechanical means that do not cause vibration or impact. Heavily deteriorated substrates should be treated by sandblasting or similar method until a surface with minimum guarantees of roughness and tensile strength is obtained. In case of heat, wind or on very absorbent substrates, it is advisable to moisten the substrate and wait for the water film to disappear. In general, the substrates must have adequate strength to support the coating (minimum adhesion of 0.15 MPa in a pull-off test). The admissible tolerances of the substrate are as follows:

System start-up The system can start above ground level or below ground level giving continuity to the thermal insulation system of the buried walls. Start-up above ground level: SATE BEYEM ECOTERM must be limited in its contour by an aluminium start-up profile appropriate to the thickness of the insulation board to be used. The starting profile must be positioned at least ≥ 15 cm from the ground, so that the system does not come into direct contact with the ground. Likewise, it must be waterproofed from ground level up to ≥ 30 cm in height, using BEYEM PROOF FLEXIBLE or BEYEM PROOF ONE, to avoid damp due to filtration or capillary action from the outside. The waterproofing must be at least 15 cm above the level of the starting profile. Start-up of the system below ground level: In this case, an XPS insulation panel with a thickness less than the thickness of the insulation panel used in the system shall be installed initially. This insulation board shall be buried and must protrude ≥ 15 cm above ground level. The starter profile shall be placed on top of the XPS panel, leaving a separation joint between the starter profile and the XPS panel of approx. 2-5 mm, which shall be sealed with polyurethane. Likewise, the aforementioned shall be taken into account with regard to the waterproofing (starting from ≥ 15 cm below the starting profile of the panels) and the finishing of the same. Laying of insulating panels The insulation boards should be installed from the bottom upwards and with a joint-breaker, with each row of boards resting on the previous one, except for the first row, which rests directly on the starting profile. At the corners, the ends of the panels should alternate. There are two different laying techniques depending on the planimetry of the substrate: Edge and point fixing: used on substrates with irregularities of between 5 and 10 mm (measured with a 2 m ruler) and for panels with a thickness ≥ 40 mm. The contact surface with the substrate shall be at least 80%. To do this, BEYEM BIOTERM is placed on the slab in a perimeter bead 4 – 8 cm wide and 2 – 4 cm thick, about 2 cm from the edge of the slab and also in the centre, where several pinches of adhesive mortar with a diameter of 8 – 10 cm are applied. The minimum final thickness of application as adhesive shall be ≈ 2 mm and a maximum of ≈ 5 mm. Fixing by means of a notched trowel: it is used when the flatness of the substrate is less than 5 mm measured with a 2 m ruler and for panels < 40 mm. Beyem Bioterm is spread over the entire surface of the board, keeping about 2 cm of the board edges free, and then combed with the help of a notched trowel of at least no. 10. Mechanical fixing of insulation boards At least 24 hours after the boards have been adhered, additional mechanical fasteners must be installed, using anchor plugs in a minimum quantity of 6 units per m2 and 8 units per m2 for heights of more than 25 metres. The fixings shall be placed on the perimeter and in the centre of the slabs. Installation of reinforcement profiles The corners and edges of existing BEYEM ECOTERM BEYEM SHEATHING openings must be protected and reinforced by using reinforcing profiles. These should be installed at least 24 hours after the panels have been fixed. The most common singular points are usually: Facade corners, windows and doors: PVC corner profile with fibreglass mesh is used. A layer of BEYEM BIOTERM is applied to the surfaces that form the corner, spreading it along the profile and the mesh, and then the profile is placed, pressing it gently. The protruding mortar is used to cover the mesh and the profile and to even it out. Window lintel and window sill: Window lintels should be reinforced with the PVC drip profile with mesh to prevent water run-off on the facade planes. The installation method is identical to that of the PVC corner profile with mesh. The sills must have a minimum outward slope of 10° to ensure water drainage. They must also have an overhang in the horizontal plane of approx. 3-4 cm with a drip edge overhanging the plane of the façade enclosure. The self-adhesive PVC window frame profile with fibreglass mesh allows the SATE to be connected to the frames of the window structure openings without leaving gaps or spaces. Top finish and expansion joints: The top finish of the façade must prevent water from running directly onto the façade. For this purpose, the crowning profile must be used and screwed in the same way as the starting profile. This profile should be installed before the last row of insulation boards and should overhang the horizontal plane by 3-4 cm. The upper part of the meeting point of this profile and the support where it is fixed must always be protected (by the eaves of the façade or overhang, another profile, polyurethane…). Expansion joints are resolved by using the PVC expansion joint profile with fibreglass mesh. The installation method is identical to that of the PVC corner profile, except that in this case there is a double edge. The strip contained in the profile is inserted into the expansion joint and then the cover of this profile is inserted. Treatment of singular points There are a series of singular points on the façade that must be reinforced with Beyem jute mesh/Beyem fibreglass mesh. These reinforcements should be installed at least 24 hours after the insulating panels have been fixed. The singular points to be reinforced are:

• Corners of façade openings (windows, doors, …): 20×40 cm strips are cut and fixed with BEYEM BIOTERM at all corners (at 45o) or the corner reinforcement mesh is used (pre-cut mesh).
• Accessible areas exposed to impact (plinths): In the area to be reinforced, BEYEM BIOTERM is spread over the insulation panels. The jute/fibreglass mesh is then spread horizontally and embedded in the mortar. This layer must be at least 1.5-2 mm thick. The joints between the meshes must overlap by at least 10 cm. The installation of this reinforcement mesh shall be additional to the installation of the main mesh.

Installation of the main mesh (jute/fibreglass) After at least 24 hours from the installation of the reinforcement profiles and reinforcing mesh, the main mesh is installed, which is the one that covers the entire surface of the facing and overlaps with the rest of the mesh reinforcements that have been previously installed. For its installation, BEYEM BIOTERM shall be spread on the slabs or on previously reinforced areas. The thickness shall be regularised with a 6 mm notched trowel. On the combed surface, spread the mesh from top to bottom with an overlap of at least 10 cm between meshes. The mesh shall be pressed against the mortar grooves so that it is embedded. This layer should be at least 2 mm thick and the embedded mesh grid should be visible on the surface. After 24 hours a second layer of BEYEM BIOTERM should be applied in a thickness of 1- 3 mm in a smooth finish to prepare the coating prior to finishing. The total thickness of the BEYEM BIOTERM coating layer on the board should be a minimum of 3 mm and a maximum of 5 mm. Decorative finish with Beyem Neocal Term 48 – 72 hours after the application of the last coat of BEYEM BIOTERM, apply a coat of BEYEM NEOCAL TERM, spreading the product with a trowel in the case of manual application or projecting it by creating beads, leaving an average thickness of 4 – 6 mm depending on the desired finish. Regulate the applied material to regularise the thickness and smooth the surface. When the product is partially hardened, proceed to the final finishing with the appropriate tool depending on the desired finish. Installation of light loads The installation of light loads on the system shall be carried out by using the Anchoring Spiral for light loads at least 72 hours after the application of BEYEM NEOCAL TERM. Maximum load 5kg.
