The experience of the Itec in the evaluation of coatings continuous of faã§ades
In this context arise the systems of isolation by the outside, formed by a layer of thermal sensors insulator with a revestimiento continuous outside, joined between himself and to the sustrato by adhesive means and/or mechanics. In general this involves to put in material contact with intrinsic properties very uneven, that have to be carefully designed and selected to offer a good conjoint behaviour, so much in the short term as on a long-term basis, taking into account the conditions of own environingingmental exhibition of the façade.
With the purpose to evaluate the answer of the systems of revestimiento continuous on isolations developed in the breast of the ‘Eota-European Organisation for Technical Assessment' an essay of behaviour higrotérmico, commonly known like ‘Eota wall', that is the European procedure with which verifies the estanqueidad to the water and the durability in the time of these construction solutions.
The essay is defined in the European guide for the systems ETICS/SATE (Etag 004 External thermal sensors sensors Insulation Composite Systems with Rendering) and also has been adopted by the Etag 017 Veture Kits, the Etag 034 Cladding kits and by procedures of evaluation (European or national) of similar systems. The essay, that reproduces a canvas of façade, consists in applying cycles combined of temperature, humidity and rain, and evaluate the resistance and durability of the solution by means of distinct determinations of adherencia and resistance to impacts, alteration of the appearance of the finishing, fisuración, etc.
This essay can realizar in the centre of Applus+ Laboratories in Bellaterra (Barcelona), that has of the team and necessary camera to evaluate systems of until 2 m of high by 3 m of width.
The
- Systems of thermal sensors isolation by the outside.
- Systems of revestimiento external continuous applied in situ for ventilated faã§ades and no ventilated (SAY YOU 13/0311).
- Systems of external walls no portantes with plates of mineral origin (SAY YOU 13/0312).
- Systems of entramado metallic autoportante with revestimiento external continuous, for his use like complete enclosures of façade no ventilated (DAU 09/052 and DAU 14/082).
The ETE-European Technical Evaluations (and the SAY YOU, now substituted by the ETE) elaborated in the frame of the Eota allow the marked CE of systems no normados and facilitate the commercialisation of the same to European level.
