Underscreed Insulation
Isolmant UnderSpecial
Product made of 5 or 10 mm Isolmant Special with the lower side bonded to FIBTEC XF1 (special needle-punched fibre produced according to specifications conceived to provide a better noise
reduction).
To be positioned with the fibre side facing down.
Application areas
Isolmant UnderSpecial ensures high impact sound insulation in floating screed application. It is suitable also when a higher air-born sound insulation is required. This product is recommended in double-layer application, installed between levelling layer and screed. It needs 6 cm (for Isolmant Underspecial 8 mm) or 7 cm (for Isolmant Underspecial 13 mm) screeds. Screeds with lower thickness should be reinforced by means of a suitable metal mesh or fibres. Attention must be paid in case of dry shake installation of ceramic tiles.
