QuietFloor Plus acoustic underlay


Quietfloor PLUS Installation Guide


The floor to be treated should be examined and any loose floorboards should be firmly secured using screw fixings so as not to squeak when walked upon. It is also extremely beneficial to seal the joints of the existing floor with our Acoustic Sealant followed by our 2mm thick mineral loaded SBM5 Soundproofing Mat. No mechanical fixings required for this but for best results, the SBM5 should be glued or nailed down using roofing felt nails. Our Soundproofing Mat can simply be laid over the floor surface wall to wall with the edges butt jointed. Our jointing tape can be used to secure the joints before installation of any further treatment if required.

Installation beneath a carpet

QuietFloor PLUS acoustic underlay installed onto a separating floor brick pattern Quietfloor PLUS can be laid by using carpet grippers.

Nail or glue our perimeter strips around the room. Nail carpet gripper rods in place on top of the perimeter strip, ensuring they are at the correct height to take the carpet. Tightly butt the Quietfloor PLUS panels against the perimeter strips and loose lay in brick-style pattern then ensure all of the joints remain tight with the aid of our Jointing Tape.

Now all that remains is to fit your carpet.  No additional underlay is required.


If Soundproofing Mat has been applied first, Quietfloor PLUS edging strips should be fitted against the skirting boards all around the room on top of the Soundproofing Mat then the QuietFloor Plus is installed from the edges of the strips across the remainder of the room. The carpet grippers required for fitting the carpet are then installed on top of the edging strips using longer nails to compensate for the additional thickness. If no Soundproofing Mat is used then install the edging strips and QuietFloor as detailed above but the QuietFloor Plus should be glued to the floor using our Sta-Put special aerosol adhesive.

Installing QuietFloor Plus onto a floor with taped joints

Installation under a vinyl floor

For vinyl and bonded carpet finishes, bond the Quietfloor PLUS to the sub-floor in brick-style pattern.  Use our Spray Adhesive only, glue a layer of 6mm MDF or ply to the top of the tiles. The MDF edge detail should be a minimum of 50mm from any Quietfloor PLUS joint. An isolation gap of 10mm should be left between the wall and the MDF then fill the isolation gap with our flexible Acoustic Sealant.  MDF or ply boards should be bonded to each other using a good quality wood adhesive.

Installation on stairs

On stairs, first cut out Quietfloor PLUS panels to the right size then bond the Quietfloor PLUS to the tread and risers of the stairs using our Sta-Put Spray Adhesive. Nail perimeter edging strips to the tread or riser and where a nosing detail is required, install a section of MDF the same thickness as the Quietfloor PLUS
