4.5mm Regupol 4515 (Sonus Multi 4.5) Acoustic Underlay Roll

4.5mm Regupol 4515 (Sonus Multi 4.5) is a tough resilient acoustic underlay manufactured from polyurethane (PUR) foam and cork granules and is ideally suited to all new build type constructions to comply with Part E 2003 and can be bonded to all types of floors, including ceramic tiles sheet vinyl and vinyl tiles, wood and laminates carpet and marmoleum/linoleum.

Acoustic materials comprised entirely of foam, particularly in a non-cross-linked configuration, have a tendency to creep (i.e. compress) over time. The addition of cork in Regupol 4515 Multi effectively reduces the risk of creep.

• Highly sustainable and completely recyclable.
  
• Offers long term performance without collapse or bottoming out under high point loads.
• Resistant to ageing and deformation.
• Quick and easy to install. Simply bond to the subfloor beneath the final floor finish.
• Reduces construction heights.
• Suitable for both new build and refurbishments.
• High quality and exact material thickness guaranteed.
• Suitable for use with under floor heating.
• Very comfortable under foot.
• Suitable for all floor finishes including ceramic/stone tiles.
• Does not cause plasticizer migration.

Ideally suited to a wide range of floors and floor finishes.

• Subfloors must be sound, smooth, dry and free from any contaminants which could affect adhesion.
  
• Ensure each roll is completely unrolled, turned over and left in the area to which it is to be applied for a minimum of 6 hours or ideally overnight prior to cutting and installing.
  
• Should be bonded to the subfloor using recommended adhesives. Lay the roll into the adhesive and press from the centre outwards to exclude air and ensure overall contact with the adhesive.
  
• Roll with a 68kg flooring roller, from end to end and side to side to ensure overall contact.
  
• Leave a minimum gap of 3mm around the entire perimeter to allow for expansion and contraction. Do not butt Regupol 3912 against the skirting boards and/or carpet grippers.
  
• Use a craft knife and straight edge for cutting to size and ensure that all edges are butt jointed.
  
• After 30 minutes, when the floor has been completely covered, roll once again to ensure contact is maintained.
  
• Do not apply loads or move furniture on Regupol 4515 Multi Acoustic Underlay until the adhesive has fully set.
