Why choose flat roof insulation?

Cost management plays a vital role in winning contracts and building long-term client relationships. In the past, many contractors reduced flat roof insulation costs by selecting hybrid solutions that combine high-performance materials like Polyisocyanurate (PIR Insulation) with budget-friendly, lower-performance options such as mineral fibre. This approach frequently meant accepting reduced overall insulation thickness. Now, 140mm EcoTherm partners with contractors to refine hybrid designs, enabling thinner, more economical flat roof insulation that maintains excellent performance—delivering both cost savings and superior results. The perfect balance.
