GENERAL SYSTEM CHARACTERISTICSempreTherm is an External Wall Insulation System (ETIC) with render coatings. The product has been given NSAI Agrément Certificate No. 11/0358 and European Technical Approval no. ETA-08/0316 issued in accordance with guidelines of European Technical Approvals ETAG 004: 2000. It concerns all products included in SempreTherm external wall insulation system.
The main objectives of the system are as follows:
- providing external walls with appropriate thermal insulation,
- increase durability of external walls by ensuring better protection from weather. The thermal insulation technology consists in fixing thermal insulation made of foamed polystyrene boards to the substrate and preparation of a reinforced layer, a render coating and, optionally, a paint coating on the insulation. SempreTherm can be used only as an adhered system or as an adhered system with additional mechanical fixing. The system can be applied on new or existing external surfaces of vertical building wall (plastered or not) made of masonry or adhered materials, such as bricks and blocks (ceramic, lime-sand, stone, cellular concrete), or of concrete (poured at the construction site or in the form of prefabricated elements). It can also be fixed on surfaces of horizontal or tilted structural elements provided that they are not directly exposed to precipitation. These may include ceilings over passages, internal walls and roofs (on the ceiling’s side) of garages or cellars adjacent to heated rooms. The substrate on which SempreTherm will be used should have reaction to fire class: A1 or A2-s1 d0 according to EN 13501-1.
