10dot20 Product Specifications

10dot20 is a free floating, smooth finish, quick and easy sub floor system ideal for glue down floor coverings including LVT’s, cork, rubber, carpet and carpet tiles. 10dot20 incorporates an acoustic foam which has been bonded with two 3mm HDF top and bottom panels, resulting in an overall system of 10mm thick (or 20mm thick for sprung extremely high performance acoustic floors). The pre-manufactured components are quickly and simply glued10doty together on site using the factory applied adhesive system eliminating the need for wet adhesives or leveling screeds. The result is a super flat finish ideal for professional floor coverings.

The 10dot20 acoustic sub floor system is ideal for floating over small floor irregularities and cracks and also well suited to float over existing finished floors such as tiled, timber, plywood, concrete etc. provided these existing floors are in reasonable condition. Removing the 10dot20 system is just as easy and will not result in any damage to the floor below. 10dot20 boards are neatly packaged in a handleable box especially suited for dry clean environments and multi-level buildings.

10dot20 provides a cost effective, simple and quick solution to many floor installation problems but also has the added benefit of having excellent acoustic dampening properties in commercial & residential multi level buildings.
