Rollable blind box thermal insulation

Thermal insulation of a rollable blind box for facade energy rehabilitation, with a length of 110 cm, formed by a flexible multi-layer panel, 1000x500x30 mm, composed of a high-density expanded polystyrene layer with a thermal conductivity of 0.035 W/(mK), a diffusion layer, and a third layer of expanded polystyrene with graphite particles, with a thermal conductivity of 0.031 W/(mK). Installation by the interior of the upper face of the box and by the interior of the register lid, with a flexible panel. Including polyurethane foam to seal both the junction area between the perimeter of the panel and the interior faces of the box and the joints between panels.
