(Notes from Seminar at Caparol Evercolor - Arcola)
By definition, the thermal coat , is a system elements formed by an insulator with plaster made integral to the wall of the building by suitable bonding and suitable hooks.
The thermal coat serves to insulate the house from the outside, to keep the heat in the winter and keep out the summer. This system contributes to the drastic reduction in primary energy consumption and consequently reduce harmful emissions into the atmosphere. In this regard, the establishment of the system, provides access to tax deductions currently in force (for example, the deduction of 55%).
The thermal coat is composed of the following elements:
Malta bonding
insulation
Tile
Rasante
network armed
Possible primer
plaster external finish.
All the elements that make up the "package" must be specifically designed and intended for the realization of COAT (ETAG004 certificates), it is advisable not to use generic materials their traditional building and do not adequately tested for this system, later we will understand why.
The laying surface (face) should be as smooth and flat as possible. On the new there are no particular problems, and urge to randomly check on the existing surface as necessary to provide for the laying and installation of suitable gripping material. If the existing facade is plastered no use of it if the removal of appropriate thickness and good maintenance, storage and mechanical strength and tangent. A good surface preparation of installation increases the functionality of malta di incollaggio.
La malta di incollaggio (colla) e la sua applicazione, rivestono uno degli aspetti fondamentali della posa del CAPPOTTO TERMICO . Sconsigliato l'utilizzo delle malte tradizionali, ci si dovrà rivolgere verso malte apposite quali malte premiscelate in polvere con leganti idraulici. Particolare importanza riveste l’applicazione della colla sul retro del pannello. Al fine di assecondare i lievi movimenti del medesimo dovuti alle escursioni termiche o vibrazioni (scosse sismiche, passaggio di mezzi, ecc…), sarà necessario applicare la colla ai bordi del l'isolante e in due punti all’interno. Questa regola is fundamental and certified installers well known to be favored.
Insulation: root element of the "coat system" sees one of the most commonly used materials the sintered expanded polystyrene (ETAG004 - EN13499) and wool (ETAG004 - EN13500). This is because - besides having a good heat resistance - these materials provide a high capacity to adjust thermal expansion and mechanical stress distribution. Other materials are not recommended. As for the natural materials we could use the wood fiber or cork, after treatment with procedures designed to increase the heat capacity and elastic. So could lose their characteristics of environmental sustainability.
To support and collaboration with the intersections of the panels fit into the so-called anchors . There are plugs for every type of surface (masonry, concrete, etc ...), for each type of panel and for any amount of tangential force to which the insulator is subjected to. They are generally made of polyethylene and metal as well as their installation needs of a particular treatment. In particular, the heads of the bolts must be "embedded" within the insulation so as not to create discontinuity on the surface.
smoother and armed Network: Even the smoothing must be fit "system coat" and then recommend a suitable material. There are several types of smoothing for coats but the main feature has to be the mechanical strength (eg hail) and flexibility to accommodate the movements induced by temperature changes and adjustments. In smoothing the network will be drowned by reinforcing fiberglass ladder-proof and resistant to alkali. Shaving is necessary to make the planar outer surface before finishing.
The topcoat is very important, must be resistant to light, water and mildew and still breathable.
There are also a myriad of special pieces what's departure, junctions, edges and angles, sealing tape, copritasselli. These accessories vary according to the manufacturers and are still used as the special cases that arise on site.
very important in a good thermal coat is the elimination of thermal bridges (windows, beams, curbs, etc ...) produced in a particular manner and, of course, accessories.
The thermal coat can not be used against the ground, then at the plans at ground level or is interrupted or goes down with traditional insulation.

Col Milleproroghe decree was set at 31 March 2011 the deadline for submitting applications to upgrade the buildings on land not declared (buildings ghost) or who have lost the requirements of rurality, initially scheduled for December 31, 2010. The amnesty was register introduced in Article 19, paragraphs 8 and following the maneuver summer DL 78/2010 .
