The 'engine' of a panel system is the insulation core. Kingspan's unique PIR insulation formula creates a superior closed cellular core fundamental to the panel system in terms of fire and thermal performance. This combined with the robust engineering of the Kingspan Curved roof panel, with its steel facings and superior joint design, make the Kingspan roof unparalleled as a weather-resilient, air-tight, low energy and highly fire resistant solution.
