GENERAL SYSTEM CHARACTERISTICS

Go top
ATLAS system is an external thermal insulation composite system (ETICS). The thermal insulation technology consists in the application of EPS boards onto the outer side of the wall, next the installation of a base coat with reinforcing fiberglass mesh, and further application of the finishing layer made of thin - coat render.

REQUIREMENTS FOR EXECUTION OF INSULATION WORKS

Go top

Work conditions

Carry out the work in dry weather, at the substrate and ambient temperature not lower than +5 °C and not higher than +30 °C. The only exception is the ATLAS STOPTER K-20 adhesive, which can also be used at 0 ° C, assuming that after 8 hours from the work completion the temperature does not drop below -5 ° C. The facade should be on time of thermal insulation work protected and secured against precipitation, strong wind and direct sunlight - it is recommended to use fine mesh scaffolding covers. Insulation works should be carried out in dry conditions (no precipitation, relative humidity below 80%).

SUBSTRATE PREPARATION

Go top
General instructions
Before the work commencement, evaluate the substrate technical condition and on that basis decide on the scope and the method of surface preparation. For the time of works remove any elements hindering tight adhesion of the thermal insulation boards and the finishing coat application. An additional layer of insulation will increase the thickness of the walls, and therefore it will cause the need to increase the reach of flashings, downspouts anchors, etc. For the time of works the windows and doors should be protected against the dirt by a plastic film.
Requirements for the substrate
The substrate should be aged, sound, stable, even, clean and dry. The absorbent substrates should be primed with ATLAS UNI-GRUNT, smooth and non-absorbent (concrete) with ATLAS CERPLAST. The substrate should be even to the extent enabling easy execution of a plane formed by the bonded insulation boards on the walls. Clean the surface from any layers which may weaken mortar adhesion, dirt, loose and dusty elements.
Note! Particular attention should be paid to the proper assessment and preparation of substrate with problematic bearing capacity, e.g. finished with glass-mosaics, glazed brick, covered with paint coats, etc. If in doubt, conduct a pull - off test of adhesion (the ultimate tensile strength should be above 0.08 MPa) or apply 8÷10 cubes of EPS 10 x 10 cm each, in various places of the facade and tear them off after 3 days. The use of thermal insulation system for buildings with reinforced concrete sandwich walls, should always be preceded by a thorough assessment of their technical condition. This applies to the technical condition of the metal fittings (hooks, pins, rods) as well as to how they are connected and interact with the elements of the wall.
Starter tracks installation

The insulation should be commenced with the installation of the starter tracks. They support the first row of thermal insulation boards, facilitate to maintain the uniform level of successive layers, strengthen the bottom edge of the system, and the bottom edge drip prevents water bleeding. The boards should be installed horizontally on the plinth of the building, not lower than 30 cm above the ground level, which provides protection from the effects of rising damp and protects against dirt - mud particles brought by raindrops reflected from the ground. Instead of skirting boards, it is permitted to use strips of armour mesh or two layers of fiberglass mesh.

THERMAL INSULATION APPLICATION

Go top
Polystyrene boards application
In the case of even substrates, the mortar can be applied with the use of a notched trowel (with notch size 12 mm)– the adhesive is applied then directly onto the board and not onto the substrate. In the case of less smooth surfaces the adhesive should be spread on the board surface using the “strip - point” method. It consists in the application of continuous circumferential bead (at least 3 cm wide) at the edge of the board and 6÷8 patches of 8÷12 cm in diameter evenly distributed on the whole surface. Peripheral bead is placed at a distance from the edge, so that when pressed to the wall the mortar is not
squeezed out of the contour and side edges. The adhesive mortar applied on board should cover at least 40% of its surface (after pressing down to the substrate at least 60%). Thermal insulation application should commence from the building corners. The first row of the boards is fixed on the starter tracks, the subsequent rows positioned so that the vertical board joints are staggered and overlapped at the building corners. It is unacceptable to fit the edges of the insulation boards with the edges of the reveals on the façade. As the adhesive is applied, the board should be placed onto the substrate, moved tightly to the already fixed boards and pressed – be sure to control the plane with a level. If the adhesive is squeezed out the board contour, it should be removed. If there are gaps between adjoining boards, we recommend filling them with cut stripes of polystyrene or low expansion polyurethane foam.
Insulation boards sanding
The surface of insulating boards applied to the substrate should be even, so when the mortar sets (after ca. 24 h), the boards should be sanded with the use of sanding boards or floats covered with coarse sanding paper. It eliminates any board edges slips. In the case of polystyrene boards installed 3 months earlier or more sanding and removal of any surface tarnish is mandatory.
Installation of additional elements
In order to increase the system resistance against mechanical damage, to allow free drainage and execution of expansion joints - the finishing profiles should be installed on the fixed insulation layer. These profiles are installed at every specific locations of the façade (i.e. corners, reveals, sills, etc.). They can also be simultaneously installed during the base coat mesh embedding.
Reveals corners strengthening
In all corners of window and door reveals, additional reinforcing mesh strips (rectangles with dimensions of 20 x 35 cm) embedded in the adhesive mortar ATLAS STOPTER K-20 or ATLAS HOTER U should be installed. The strips should be applied diagonally, at a 45° angle in relation to the line set by the edges of the reveals.
Mechanical fixing
The additional fixing with the use of mechanical fasteners with plastic pins can commence after ca. 24 hours from the boards application. Detailed information about the number of fixings, their distribution, length and depth of anchorage should be specified in the thermal insulation technical design and meet the requirements of the fixings manufacturers.
Base coat (reinforced layer) application
The base coat can be installed once the adhesive mortar used for board application has sufficiently set and any necessary additional mechanical fixings have been installed (after three days on average). Apply the adhesive mortar onto the surface of the installed insulation boards and spread it using a notched trowel (notch size 10 - 12 mm). The adhesive should be spread in vertical strips of width slightly greater than the fiberglass mesh width. Then, starting from the top, subsequent strips of mesh are applied and in a few points along the entire length embedded in the prepared adhesive layer. The adjoining strips of mesh should overlap horizontally and vertically by a minimum coverage of 10 cm (15 cm in quoins). Mesh overlaps should not coincide with the joints between the insulation boards. When applied, the mesh should be carefully embed in the adhesive. In order to embed the mesh evenly, the adhesive is squeezed with the slightly inclined trowel led from the top, in the direction from the center to the mesh strip side. The correctly embedded mesh should be completely not visible under adhesive coat and should not be in direct contact with the polystyrene boards surface.
Façade finishing
The outer layer of the system may be a thin-coat render solely or a thin-coat render coated with a façade paint. The execution of the finishing layer can start after ca. 3 days from the reinforced layer installation. You can use thin - coat render: ATLAS CERMIT (mineral or acrylic), ATLAS SILKAT (silicate) or ATLAS SILKON (silicone). The renders surface can be painted optionally with ATLAS ARKOL E, ATLAS ARKOL S, ATLAS ARKOL N or ATLAS FASTEL NOVA facade paints. All works must be performed in accordance with the technology described in the technical data sheets of the individual products.
