Aluminium vapor barrier SUN'X

reflective

Reflecting roof underlay fitted with aluminium foil on its surface for improving temperature comfort in summer. Very strong reflectivity due to its surfacing in aluminium foil: improvement of temperature comfort in summer in inhabited attics. Hydrophobic underface that captures the micro-droplets (any condensation) that can then be more easily vaporised and transferred into the ventilated air layer under the underlay, without seeping into the insulation. MAIN USES Plains climate: under altitude of 900 m; Premises with low or medium humidity; Roofing of small elements (clay tiles or slates); Roof renovation work (attics not suitable for conversion as well as converted attics); New roof works (additional thermal insulation for improved thermal agreeability in summer). APPLICATIONS Taut laying, ventilated on 2 faces, on rafters or on underlying truss components with maximal on-centre of 60 cm; Laying on continuous ventilated substrate.
