TRUST WHATS UNDERNEATH

TSU-01 plywood underlayment is an engineered hardwood plywood designed to provide the ultimate substrate for floor coverings.
Manufactured using fully exterior-grade phenol-formaldehyde resin and precision-engineered hardwood veneers, you can trust in “what’s
underneath.”
BS 8203 TSU-01 plywood exceeds the requirements of BS 8203:2017, Annex A — flooring-grade plywood guidelines.
FSC® FSC 100% veneers. Eucalyptus, a non-tropical hardwood from FSC-certified plantations, helps protect tropical rainforests and the wider
environment.
GLUE BOND Conforms to the highest bond class standard, BS EN 314-2 Class 3, using phenol-formaldehyde resins and veneers dried to 8–10% moisture
content.
STRENGTH Four-ply construction provides greater strength and stability than usual three-ply panels. Eucalyptus veneers give a density of 585–650 kg/m³,
enhancing screw-holding and fixing capability.
CORE Machine-jointed core veneers help prevent gaps or overlaps that could telegraph through the finished floor covering.
FACES 1.3 mm face veneers help prevent blistering and weak bonds associated with thinner veneers. Natural face defects are repaired, filled and
sanded.
CFA Manufactured in accordance with, and certified as fully compliant with, CFA Guidance and BS 8203:2017 — Code of practice for installation of
resilient floor coverings: plywood specification.
