ISOLMANT UNDERSPECIAL RADIANTE BV UNDERSCREED INSULATION Specific for underscreed impact sound in double screed layer applications with underfloor heating. Finishing screed with average height of 5 cm. SPECIFIC APPLICATIONS WHAT IS ISOLMANT UNDERSPECIAL RADIANTE BV High performance resilient Isolmant Special polyethylene layer joined on the upper side to a radiant tear-proof and aluminate film and on the lowerside to FIBTEC XF3 (special needle-worked fibre produced according to specifications designed to provide a better noise reduction). It provides excellent impact sound and airborne insulation for horizontal partitions. Thickness 10 mm. Isolmant UnderSpecial Radiante BV is specific for floating screeds as provided by UNI 11516:2013 standards with any type of slab. This product is specific for applications with hot/cold water underfloor heating (a resilient underlay is always required since thermal panels do not provide impact sound insulation) even in the case of low screed thickness or anywhere a vapor barrier is required. When installed under the radiant system panel, it requires a radiant flooring finishing with 5 cm average thickness. In order to disjoint a floating screed from perimeter walls, it is recommended not to turn Isolmant UnderSpecial Radiante BV upside down but to use Isolmant Fascia Perimetrale. Install Isolmant UnderSpecial Radiante BV with the reflected film facing up and the fibre side facing down. 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 UNDERSPECIAL RADIANTE BV > 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 s available in different thicknesses and densities depending on the weight of the partitions (fig.A) DISJOINT OF REINFORCED CONCRETE STRUCTURES In the presence of stairwells, elevator compartments and pillars (even if contained...

ISOLMANT UNDERSPECIAL RADIANTE BV > 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 band 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...

ISOLMANT UNDERSPECIAL RADIANTE BV > 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 regard to the thickness of the finishing...
