ATLAS External Thermal Insulation Composite System (ETICS) with render coatings has been given European Technical Approval no. ETA-06/0081 issued in accordance with guidelines of European Technical Approvals ETA 004:2000 and NSAI-Irish Agrément Board Certificate No. 10/0347
The main objectives of this system are as follows:
- Providing external walls thermal insulation,
- Increase durability of external walls by ensuring better protection from weather.

External Wall Insulation
Thermal insulation made from polystyrene boards fixed to the external wall followed by reinforced layer and then render coating. ATLAS can be used only as an adhered system or as an adhered system with additional mechanical fixing.
The external insulation system can be applied on new or existing external surfaces of vertical walls (plastered or not) made from masonry such as bricks, blocks, stone, cellular concrete or concrete.
The insulation system can also be fixed to horizontal surfaces other than roof. These may include ceilings over passages. Internal walls and roofs (on the ceilings side) of garages or cellars adjacent to heated rooms.
The substrate on which ATLAS will be used should have reaction to fire class: A1 or A2-s1 d0 according to EN 13501-1.
External Insulation – Cloverhill N.S.
Specification of the external insulation system and its individual parts ensure that all technical, usable and utilisation requirements assumed for the intended use are met by correctly designed and constructed thermal insulation.
In respect of reaction to fire, ATLAS external insulation system has been classified according to EN 13501-1 as:B – s2,d0 for a system with polystyrene board not exceeding 250 mm thickness, finished with ATLAS CERMIT or ATLAS SILKON; C –s2,d0 for the system with polystyrene board not exceeding 250 mm thickness, finished with ATLAS CERMIT or ATLAS SILKON.
Water absorbability of the reinforced layer and individual layer and individual finishing layers specified after 24h in each variant does not exceed 0.5kg/m2; therefore, the system is resistant to freeze-thaw cycles. ATLAS external insulation system is also fully resistant to thermal-humid cycles. In relation to the impact strength, regardless of the arrangement of finishing layers (with one layer of glass fibre mesh), the system has been classified for III utilisation category.
If correctly installed, the external insulation system prevents surface and internal water vapour condensation. Diffusion resistance, expressed in equivalent thickness of air layer Sd for the least favourable arrangement of the finishing layer in the system (including a paint coating) is only 0.49 m. The manufacturer declares that adhesion between the reinforced layer and thermal insulation (EPS), and the adhesive and thermal insulation is no less than 0.1 MPa, where as between the adhesive and substrate (concrete) is no less than 0.6 MPa.
The manufacturer declares that adhesion between the reinforced layer and thermal insulation (EPS) and the adhesive and thermal insulation is no less than 0.1 MPa. Thermal resistance of the finishing layer of the insulation system (the reinforced layer with the render coating) render is ca. 0.02 m2 K/W.
