Flat Roof Decking Plywood Insulation Panel (Ecotherm)

Flat Roof Decking Plywood Insulation Panel (Ecotherm) is a composite warm-roof board combining rigid PIR insulation with a bonded plywood face. It provides high thermal performance, stable load-bearing support and consistent membrane adhesion in flat roof build-ups. The closed-cell PIR core limits heat transfer and moisture absorption, improving long-term thermal integrity.

The plywood facing creates a strong substrate for mechanical fixings, single-ply membranes, bituminous systems and liquid-applied roofing. This supports fast installation and reduces the number of layers needed in warm-roof assemblies. The board remains dimensionally stable under load and temperature variation, helping maintain roof levels and preventing settlement.

The panel suits new-build and refurbishment roofing on timber, concrete or steel decks. It improves energy efficiency, reduces heat loss and helps achieve compliant U-values in modern flat roof designs. Buyers use this panel when they want reliable insulation, strong membrane bonding and simplified warm-roof construction.

Installation Guide:

• Ensure the structural deck is clean, dry and sound
• Position boards tightly with staggered joints to reduce thermal bridging
• Fix mechanically through the plywood face using approved warm-roof fasteners
• Seal or tape joints if required by the selected roof membrane
• Apply single-ply, bituminous or liquid systems directly to the plywood top layer
