LAMINATE/WOODFLOOR UNDERLAY (Part Code A300)

This is a superb acoustic underlay designed specifically to reduce the transfer of impact noise (walking/footfall) through floating laminate, engineered wood and solid timber floors. The main problem with wooden/laminate floors is that when you walk on them much more impact as well as airborne noise is produced (due to the hard surface) and this can often be a nuisance to the people living below.

This product comprises a nominal 3.5mm layer of high density resilient rubber sponge with a foil faced moisture barrier laminated to one side. Easily cut with a knife or scissors and when used in conjunction with our Tecsound50 Acoustic damping sheet first will provide both impact AND airborne noise reduction through the floor for minimal height rise.

INSTALLATION

Simply roll out the underlay across the floor foil side down. The joints should be butted tightly together and joins should be sealed with our self adhesive aluminium tape.

ACOUSTIC PERFORMANCE

Weighted Impact Sound Improvement Index (Delta Lw) 24dB
This is a substantial improvement in impact noise transfer over not having an acoustic underlay and if soundproofing mats are used in conjunction as well then this figure will be even higher.

Self-Adhesive Foil Tape Application Instructions

  • The surface to which the tape is to be applied must be clean and dry. Dust, dirt, oil, grease and moisture on the surface will result in poor adhesion.
  • For best results, before applying the tape, the surface should be wiped clean with a safe solvent, using a lint free cloth. Solvent must be fully evaporated before application of tape.
  • Fix insulation carefully so that slabs or sections abut with no gaps. Open joints will permit localised heating which may in turn affect the adhesion of thre foil tape. Do not unwrap unsulation until immediately required for use.
  • When bonding to an embossed or ribbed surface the tape may not be in 100% contact so adhesion values will be reduced. Allowances must be made for this by using tape of adequate width. THis is a minimum of 50mm on good flat close butt joints. However on angled or contoured surfaces use tape wide enough to allow 50mm either side of the join.
  • Remove tape from roll, discard release paper, align tape centrally over joints and rub down well over the entire area of the tape taking care to avoid wrinkles, folds and undue tension. Avoid touching the adhesive surface as dirt, oils and grease may be transfered and impair adhesion.
  • Allow an adequate overlap of the tape onto itself of at least twice its width. If possible fold back about 25mm of one end of the tape so that when the overlap is made this section of the bond will be adhesive on adhesive.
