Description

This 120mm Inno-Bond product features a fibre-free, rigid polyisocyanurate (PIR) insulation core, combined with coated glass tissue facing on both surfaces to enhance durability and performance characteristics.

Why choose flat roof insulation?

Cost management plays a vital role in winning contracts and building lasting client relationships. Contractors traditionally reduce flat roof insulation costs by selecting hybrid insulation solutions that combine high-performance materials like Polyisocyanurate (PIR Insulation) with more economical, lower-performance options such as mineral fibre. This approach often meant accepting reduced overall insulation thickness. Modern solutions like 120mm EcoTherm enable contractors to refine hybrid schemes, delivering thinner, cost-effective flat roof insulation that maintains excellent thermal performance—achieving both financial and efficiency gains. The ideal balance.
