Thermoplus 80

EPS insulation panel (sintered expanded polystyrene) with GRAPHITE, for external thermal insulation systems

Product Description

Thermoplus 80 is a sintered expanded polystyrene panel, cut from a block, obtained with the use of virgin granulate and post-consumer material in the minimum quantity of 10%. The raw material, expanded and sintered in modern systems and additive with flame retardant, it meets the requirements of the Ministerial Decree of 11 October 2017 (Minimum Environmental Criteria – CAM). Thermoplus 80 insulating sheets are in Euroclass E, they are unassailable from mold and have good vapor permeability.

Application Procedure

Preparation of the substrate

The substrate must be compact, resistant, free of dust and free from incoherent parts, greases, oils, glues, etc. It is recommends eliminating any significant unevenness in cement surfaces using a leveling mortar for interiors and exterior or cementitious adhesive mortar. The plaster supports, before proceeding bonding of thermal insulation panels, must be treated with DCI Grip Primer.

Laying the slabs

The slabs must be fixed directly on the reverse using cementitious adhesives. In case of plastered and flat support with a 10 mm notched trowel over the entire surface, or with a curb points if there is no flatness of the masonry. The installation of the panels must take place starting from the bottom upwards, Thermoplus 80 insulation panel, for thermal insulation systems a coat placing them with the longer side in a horizontal position, staggering the vertical joints by at least 25 cm. In correspondence of the edges, the heads of the panels must be alternated. After installation, press the panels well so to ensure good adhesion to the substrate by checking the flatness with a straightedge.

Application of base coat

The smoothing of the panels must be carried out after complete drying of the adhesive, considering the conditions climatic, spreading the smoothing mixture on them in uniform thickness and incorporating the fiberglass mesh alkali resistant. The mesh must be pressed onto the fresh adhesive with a smooth trowel and the adjacent sheets must overlap by at least 10 cm. After 12-24 hours apply a second coat of smoothing to obtain a compact and regular surface suitable for receiving the finishing coating, which must be applied only when the smoothing compound is well hardened and cured.
