3.5mm Isocheck Underwood is a rubber crumb underlay for use with laminate and wood flooring to provide resilience, durability and support to protect against undue stress in wood and laminate flooring. Isocheck Underwood is manufactured mainly from recycled vehicle tyres bound in a unique latex formulation. The integrated metallised scrim ensures good resistance to moisture transmission, eliminating the need for additional polythene sheeting. Isocheck Underwood is ideal for underfloor heating systems beneath laminate and engineered wood flooring.

CHARACTERISTICS
  • Made mainly from recycled vehicle tyres,
  • Suitable for laminate and wood flooring,
  • Excellent impact sound insulation properties,
  • Ideal for underfloor heating,
  • Integral moisture barrier.
  • Can be used also on concrete floors, on top of the screed.
APPLICATION
  • Over existing floorboards,
  • On timber joisted floors,
  • Refurbishment,
  • Conversion projects,
  • New build.



INSTALLATION
  • Lay Underwood over the entire level floor with all joints tightly abutted.
  • Most t&g or interlocking engineered timber panel floor finishes can be laid directly onto Underwood.
  • Finished timber floors should be isolated from the skirting using Isocheck Acoustic Flanking Band.
