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 when a higher air-born sound insulation is required. In particular, this product is recommended in double-layer application. 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.
