ISOLMANT SPECIAL UNDERSCREED INSULATION Essential product specific for underscreed impact sound in double layer solutions with finishing value ranging between 4 and 7 cm. WHAT IS ISOLMANT SPECIAL? SPECIFIC APPLICATIONS Resilient layer in second-generation Isolmant polyethylene with embossed and screen-printed upper side, featured by a better and calibrated quality of the polyethylene cellulation. Thanks to its intrinsic quality and physical properties, this product ensures long-term performance. It provides excellent impact sound and airborne insulation for horizontal partitions. 3 mm, 5 mm, 10 mm and 15 mm thickness available. Isolmant Special is specific for floating screeds as provided by UNI 11516:2013 standards with any type of slab. This product is recommended for applications under a finishing screed (double layer solution), it requires a finishing screed at least 4 cm thick (for 3- 5 mm Isolmant Special) and at least 7 cm thick (for 10 -15 mm Special). In case of disjointing a floating screed from perimeter walls, it is recommended not to turn Isolmant Special upside down but to use Isolmant Fascia Perimetrale. Install Isolmant Special with the embossed and screenprinted side facing upwards. Thicknesses available: MINIMUM ENVIRONMENTAL CRITERIA All our products with the “Guaranteed Green Planet” logo are compliant with the sustainability criteria of the most important environmental protocols and certified according to the major national and international standards.

ISOLMANT SPECIAL > INSTALLATION INSTALLING FASCIA TAGLIAMURO Before installing all the partitions, Isolmant Fascia Tagliamuro must be laid. This high density,reticulated polyethylene foam accessory is specifically designed to disjoint partitions and slabs, thereby helping to reduce the structural sound transmission from the walls to the slab. This product is available in different thicknesses and densities depending on the weight of the partitions (Fig.A) DISJOINTING OF REINFORCED CONCRETE STRUCTURES In the presence of stairwells, elevator compartments and pillars (even if contained within the...

ISOLMANT SPECIAL > INSTALLATION INSTALLING FASCIA PERIMETRALE To avoid acoustic bridges, the use of Isolmant Fascia Perimetrale is recommended, to be laid along the entire perimeter of the room without interruption. The height of Isolmant Fascia Perimetrale must be chosen by the designer/contractor, taking into account the actual height at each site, in order to guarantee that the strip is about 2/3 cm higher than the flooring level. This excess must be trimmed after laying the floor (Fig. E). The continuity of the installation must also be ensured along the thresholds of entrance doors and French...

ISOLMANT SPECIAL > INSTALLATION SCREED CONSTRUCTION The finishing screed must guarantee adequate mechanical resistance according to the actual laying and loading conditions. Appropriate safety measures must be taken, such as assessing the adequate consistency of the mix, the curing time, the possible need to use collaborating elements (wire mesh or fibres), the sufficient compactness of the surface and the possible surface treatment with consolidating products (as indicated by the manufacturer of the screed and the reference standards). With reference to the thickness of the finishing screed,...
