In dwellings without insulation or insufficient insulation, a heat transfer is constantly carried out “ heat flux” from’ internal towards l’ external in cold periods and from’ external towards l’ internal in hot periods. Causes these mainly due to the 26-wall radiation and capacity? of building materials to transmit heat (conduction).
The system “ PAULINKOIBENTA” obtained at I’ ITC-CNR (Institute for Construction Technologies) the ETA Certification n° 08/0354 (European Technical Approval) or the European technical approval, certifying that the system has passed a strict cycle of tests and guarantees a high level of performance and represents a declaration of compliance of the product with the specific standards in terms of stability? mechanics, fire safety, hygiene, acoustics and energy saving.
The compliant system in all components to the ETAG 004 Guidelines e? consisting of:
1. powder adhesive for l’ bonding and shaving of insulating panels.
2. insulating slabs in sintered expanded polystyrene (EPS 120).
3. reinforcement with fiberglass mesh (alkali resistant), sized.
4. powder adhesive for smoothing thermal insulation panels.
5. priming layer.
6. finishing layer.
7. system accessory materials: corner profiles - edge protectors - plugs.
In case of laying in new buildings, should the conditions of flatness be checked and restored, if necessary? of the support, its accurate and correct seasoning, its cleanliness against dust or traces of disarming. In the case of installation in existing buildings, the conditions of flatness, absence of general and localized deterioration, removal or consolidation of paints and plasters that are not capable of guaranteeing must be verified and restored, where necessary. good adhesion over time. IS? also necessary to proceed with the cleaning of the support and the verification of the 26-rsquo; absence of permanent phenomena of rising damp?
LAMPOKAPPA R631. Adhesive-skim coat in powder form based on modified hydraulic binders, granulometrically selected siliceous aggregates and special polymers with very high resistance to saponification.
Laying the insulation
On masonry and on non-planar substrates or with irregularities (which must not exceed cm in height), the gluing of the panels always takes place in points, applying the mortar in strips along the edges and always in points in the center of the panel . N.B. Contact surface (bonding) ≥ 30%. On very regular surfaces, bonding can be done with a notched steel trowel over the entire surface of the panel, at a rate of at least 4-5 kg / m2. The panels must be positioned on the surface (matching each other perfectly) with staggered vertical joints, starting from the bottom upwards, beaten with a wooden trowel, checking the flatness of the laid at regular intervals. Simultaneously with the laying of the slabs, proceed with a mechanical fixing, using the provided plugs, in the ratio of 6-8 / m2. LAMPOPLACO EPS 120: Insulating panel in flame-retardant sintered expanded polystyrene (class E), CE marked according to the applicable standard EN 13163, having Thermal Conductivity λ≤0,036 W / m · K available in thicknesses of 40 at 360 cm The thickness of the insulating panel to be applied to the support is calculated by the designer and / or the heating technician according to the climatic characteristics of the project, the type of wall support and the specifications reported in current legislation. RETE 160-A: Resistant alkali fiberglass mesh, reinforced by reinforcement. Rectangular mesh latticework 3.80 x 4.14 mm, green area: 155 g / m2
Laying of the base layer: In a period of time between 2 and 7 days from the laying of the insulation and in relation to the environmental thermohygrometric conditions, the base layer is laid using the adhesive similar to that used for laying insulation slabs. Metal sections (corner profiles, profiles, corner pieces, etc.) must be arranged beforehand. The time between the laying of the panels and the shaving varies from a minimum of two days (hot and dry climate) to a maximum of one week (cold and damp climate), drowning in the thickness (between the 1st and 2nd hand) the reinforcement mesh, spread from top to bottom with an overlap of at least 10 cm at the joints. Any necessary reinforcements are obtained by doubling the net. The quantity of adhesive used must be at least 4 kg / m2. After a period of at least 48 hours from the laying of the base layer, the primer layer is applied with a roller or a brush. FIXACRIL: Fixative base with strong penetration based on acrylic microemulsion. FIXACRIL PIGMENTATO: High coverage pigmented acrylic water-based primer.
In a period of time between 2 and 10 days from the laying of the base layer and of the 26-rsquo; reinforcement and in relation to the environmental thermohygrometric conditions (and in any case with a perfectly dry surface), it is applied (application with d-26 trowel - steel and finishing with plastic trowel) the finishing layer on the basis of:
1. 2.0– 2.5kg / m2 for LAMATOCOAT120PREVEN– SANOCOAT120– SILOXCOAT120
2. 2.5– 3.0kg / m2 for LAMATOCOAT150PREVEN– SANOCOAT150– SILOXCOAT150
