BRANDS: Envoy®


  • an ideal insulating material for wooden, laminated and concrete floors
  • compensate uneven spots of the floor
  • do not absorb water
  • durable and chemical resistant
  • resistant to pressing and tearing
  • reduces the noise at a level below
  • easy to assemble and process
  • can be laminated with different products as LDPE, HDPE, metalized film, anti-slip, in different thicknesses
  • recommended for heavy duty floors
  • light and it lays evenly
  • they ensure high parameters of moisture and sound insulation
  • perfect for floor heating systems and places particularly exposed to moisture

Available options:

Luxury vinyl tiles (LVT) underlays

This underlay from 100 kg/m³ till 400 kg/m³ density and thicknesses from 1 mm till 2 mm is supplied in convenient rolls of 1m and 1,20m and lengths of 10m, 15m, 20m. Other lengths on request.

We have a full assortment of acoustical underlays for Multilayer Modular Floor coverings (vinyl flooring) who comply with the latest regulations following EN 16354; and are certified by leading European acoustic laboratories. We have reports from among other Tüv and the Dibt in Germany.

Laminate floor underlays

This underlay from 20 till 400 kg/m³ density and thicknesses from 1 mm till 3 mm is supplied in convenient rolls of 1m and 1,20m and lengths of 10m, 15m, 20m, 25m or longer strips for professional use.

Concrete floor underlays

Manufactured from 5 and 10 mm foam they provide acoustic and thermal insulation possible use:

  • Underlays for floating floors assembled between the concrete slab and the screed with the use of the edge dilatation strip
  • Protection from freezing temperatures and too quick drying of concrete
  • They are durable, do not absorb water and do not stick to the concrete


Thermo insulating products

Manufactured from the highest quality foam meshed with an additional thermal screen in the form of a metalized film:

  • it reflects infrared radiation thus contributing to better thermal insulation
  • used behind a radiator in houses or offices they optimize the heating costs

Dilatation tape

Ideal as compensating connectors which eliminate the unwanted influence of the thermal expandability of concrete floors:

  • light, durable, flexible and easy to use
  • resistant to chemicals used in the construction industry
  • can fill up the dilatation gaps in buildings, tunnels, underground passageways, bridges and roads

Available as premium:

  • with cuts
  • with a self-adhesive tape
  • with LDPE flaps
