Concrete Floors Under Screed: Regupol 7210 C

Concrete Floors Under Screed - Regupol 7210 C

Regupol 7210C is an under screed product designed to isolate screeds from the main structure of the building, reducing impact energy generated by general footfall.

Other items required with this product:
Regupol Approved Adhesive
High Tack Tape

Regupol 7210C is used under all types of floor screeds in new build apartments and is aimed at constructions where Pre-Completion Testing (PCT) is preferred to that of a Robust Detail (RD).

Has been independently tested on-site to show compliance with the new building regulations in accordance with Approved Document E 2003.

• Approved by NHBC for ADE 2003 compliance.
• Excellent impact and airborne performance.
• Offers long term performance without collapse or "bottoming" out under high point load
• Minimal creep, even under high loads.
• Resistant to ageing and deformation.
• Quick and easy to install. No need for separate perimeter strips.
• Minimises construction heights.
• High quality and exact material thickness guaranteed.
• Suitable for use with underfloor heating.
• Protects expansion joints.
• Supplied in easy to handle sheets.

*Building regulations Approved Document (2003) requirements 45dB or greater (performance figures obtained from independent testing).
**Building regulations Approved Document (2003) requirements 62dB or less (performance figures obtained from independent testing).

Supplied in sheet sizes 2.3m x 1.15m x 5mm
(1 full sheet - 2.65m²) (110 Sheets per Pallet)

A suggested Regupol Corner Piece can be used alongside the Regupol underscreed range to provide added acoustic insulation. Fitting both internal and external corners, the Regupol Corner Piece offers peace of mind that the potential ‘weak spots’ do not compromise the acoustic performance of the floor.

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 where possible, Dry. Please check that you have the correct number of Regupol Corner Pieces.One Regupol Corner Pieces should be used for each internal corner.

1. The Regupol 7210 C is supplied in sheet form. A sharp craft knife and straight edge must be used for cutting to size.
   
   
2. 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).
   
   
3. Unroll a full width piece of Regupol 7210 C making allowance for the 100mm upturn at each end. Cut a 230mm x 230mm square piece from the Regupol 7210 C in the corner that will overlap the corner piece. Move the Regupol 7210 C 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).
   
   
4. Overlap all joints (both along and across the roll) by at least 50mm and tape all joints using Regupol Tape only (see Fig. 3).
   
   
5. Turn up edges at walls to ensure the screed will not touch the walls and is of sufficient length to lap under wall linings and skirtings (we recommend the length be 100mm) (see Fig.4a).

Lay a waterproof membrane (e.g. Visqueen), minimum of 0.2mm thick over the entire area (see Fig. 4b).

You can now cast the screed taking the usual precautions to avoid damaging or moving the membrane and the Regupol.
