Why choose flat roof insulation?

Keeping costs down is vital for winning contracts and building customer loyalty. In the past, contractors have reduced flat roof insulation costs by choosing hybrid insulation solutions. These often pair a thin, high-performance material, like Polyisocyanurate (PIR Insulation), with a more economical, lower-performing material such as mineral fibre. This approach typically meant accepting a compromise on total insulation thickness. Now, 50mm EcoTherm partners with contractors to refine hybrid schemes, enabling thinner, more economical flat roof insulation solutions that maintain excellent performance—delivering both cost savings and superior efficiency. It's the ideal combination.
