Why choose flat roof insulation?

Keeping costs competitive is vital for winning contracts and building long-term client relationships. In the past, many contractors reduced flat roof insulation costs by selecting hybrid insulation solutions. These typically pair a thin, high-performance material like Polyisocyanurate (PIR Insulation) with a more economical, lower-performing option such as mineral fibre. This approach often meant reducing overall insulation thickness. Now, 100mm EcoTherm partners with contractors to refine hybrid designs, enabling thinner, more economical flat roof insulation solutions that maintain excellent performance—delivering both cost savings and superior efficiency. The perfect balance.
