Description

Calcium sulfate based screed for use in a SoundBar system, which is designed for use over timber joists both in masonry and timber framed construction. The system can be used in both commercial and residential projects and is ideally suited where improved acoustic, loading and durability are required. Particularly suitable for use with under floor heating.

Gyvlon Soundbar is a blend of Gyvlon binder, special additives and selected aggregates mixed with clean potable water to produce a pumpable, self smoothing flowing screed (manufactured to BS EN 13813).

Features:

  • Can easily accommodate under floor heating within the screed zone and has excellent performance compared to floating floors.
  • Easily achieves SR2 finish as described in BS 8204.
  • Improved loading compared to timber batten floors.
  • Increased productivity - up to 1200 m²/day can be achieved.
  • Minimal thermal expansion (0.012 mm/mK).
  • No need for loading out prior to flooring.
  • Protein free - cannot harbour harmful bacteria.
  • Self compacting.
  • Self curing.
  • Significantly reduced thickness when compared to traditional sand/ cement screed.
  • Weight saving as a result of thinner section.

Primer:

Requires priming prior to application of adhesives; generally acrylic dispersion or water based epoxy.
