The ASPIRE Solution unites a tapered Expanded Polystyrene (EPS) base layer with a flat polyisocyanurate (PIR) top layer. The solution delivers an excellent combination of versatility and cost-effectiveness, making it a popular choice for many applications.


PIR insulation boards are available with a wide range of facings providing compatibility with all popular waterproofing membranes, and offer excellent thermal performance. The EPS base layer allows easy machining to provide great flexibility of falls.

The ACOUSTIC Solution combines high performance PIR insulation boards with mineral fibre and a Building Innovation High Mass Acoustic Membrane to provide a bespoke and optimised solution, designed to meet both acoustic and thermal requirements of a roof.


The PIR insulation boards are lightweight and their excellent thermal performance allows U-values to be achieved with practical thicknesses. The mineral fibre slab provides acoustic insulation, an important feature for educational and healthcare buildings.
