Regupol E48 (REGUPOL sonus curve 8) acoustic flooring material is a high performance recycled tyre crumb used for under screed and designed to isolate screeds from the main structure of the building reducing the impact energy generated by general footfall.

Regupol E48 (REGUPOL sonus curve 8) acoustic flooring material is used under all types of floor screeds in most new build constructions such as; Apartments, schools, hospitals, hotels, libraries and supermarkets.

Unroll the Regupol. When the product is rolled up it stretches slightly. Unwind each roll where it
is to be installed and leave it for a few hours before measuring or cutting to length.

Prepare the base floor. It is important that the base floor is clean, (free from loose dirt and concrete dust) flat, (within National Building Standards +/-5mm over a 5m span) and dry.

Unroll the Regupol. When the product is rolled up it stretches slightly. Unwind each roll where it is to be installed and leave it for a few hours before measuring or cutting to length.

Please check that you have the correct number of Regupol® Corner Pieces. One Regupol® Corner Piece should be used for each internal corner.

The Regupol must be laid dimple side down. Use a sharp craft knife and straight edge for cutting to size.

Position the Regupol Corner Pieces into each of the internal corners, with the bottom folds laid flat on the sub-floor for stability purposes(see Fig. 1).

Unroll a full width piece of Regupol E48 (REGUPOL sonus curve 8) acoustic flooring material making allowance for the 100mm upturn at each end. Cut a 230mm x 230mm square piece from the Regupol E48 (REGUPOL sonus curve 8) acoustic flooring material in the corner that will overlap the corner piece. Move the Regupol E48 (REGUPOL sonus curve 8) acoustic flooring material to overlap the Regupol® Corner Piece and turn it up each wall by 100mm. Ensure that all overlapping edges are taped with Regupol tape (see Fig. 2).

Overlap all joints (both along and across the roll) by at least 50mm and tape all joints using Regupol tape only
(see fig. 3).

Turn up edges at walls to ensure the screed will not touch the walls and is of sufficient length to lap under the wall linings and skirtings (we recommend the length be 100mm) (see Fig. 4a).

Lay a waterproof membrane (eg. Visqueen), minimum of 0.2mm thick over the entire area (see Fig. 4b). Overlap all joints by at least 100 mm and tape all joints using Regupol tape only.

You can now cast the screed taking the usual precautions to avoid damaging or moving the membrane and the Regupol E48 (REGUPOL sonus curve 8) acoustic flooring material.

Regupol Corner Pieces have been specifically designed to isolate internal corners where floating screeds are used and will complement both Regupol E48 (REGUPOL sonus curve 8) and Regupol 7210 (REGUPOL sonus core 5) acoustic underscreed materials, the former of which is now a proprietary product on Robust Details no. E-FC-6.

Regupol Corner Pieces eliminate the worry associated with the cutting/fitting of acoustic materials into internal corners, which can be deemed as ‘weak’ spots.

REGUPOL adhesive 46-101 represents the very latest development in Hybrid Polymer technology and has been formulated to give the highest levels of performance in terms of bond strength, versatility across many combinations of materials, improved acoustic performance in acoustic installations, resistance to stresses, fast curing speed and ease and cleanliness of use.

REGUPOL adhesive 43-105 is a solvent free acrylic emulsion-based adhesive, for bonding many sound insulation materials to common sub-floors and many floor finishes to the insulation. This easy to spread adhesive, with a long open time, provides early tack and minimum slip, quickly building to a strong permanent bond. It is non-staining and has excellent resistance to plasticiser migration.
