Technical Installation Guide
- Ensure that the product is always stored under cover in dry moisture free conditions.
- Handle with care when moving around the site or unpacking to avoid damage to the edges and corners.
- The building should be watertight before installation.
- Ensure sub-floor is thoroughly swept and free from extraneous material.
- Since the foam laminate is moisture repellent there is no requirement for a vapour control layer.
- Lay resilient foam layer down.

|
- Measure up room and cut boards 5mm short of wall to accommodate E-Cousti flanking strips.
- Stagger the joints ensuring that the tongue and grooves are tightly fitting to avoid any gaps for sound to penetrate.
- Joints must be glued using adhesive and left for 12 hours before walking on.
- Under no circumstances should the boards be fixed through to the sub-floor.
- Insert flanking strip as you go and ensure the boards are pushed tightly against the strip. Do not leave any gaps in the strip and ensure that at no point the boards of the floating layer contact the walls of the structure as this will allow flanking and structural transmission of sound and impair the acoustic performance of the floor.
- Complete the installation by turning the protruding part of the flanking strip over the board and trap below the skirting to completely isolate the floor from all other hard surfaces. Trim off any excess with a sharp knife and seal the junction with E-Cousti Fix and Seal.
