The ASPIRE Solution

ApplicationRender_ASPIRE Hybrid Solution_UK_BI edited3
No one insulation type excels in all areas of performance. 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 both new and refurbished flat roofs.

The ASPIRE Solution utilises tapered EPS 150E insulation to create the required falls, over which a rigid PIR insulation layer is either fully adhered or mechanically fixed, and receives the waterproofing system. The ASPIRE solution is suitable for use with metal, concrete or timber roof decks – eliminating the requirement for other means of creating a fall such as structural falls, timber firings or screed laid to falls.
