Profiled PIR Infill Overlay System

The system incorporates a PIR insulation infill that is cut to match profiled sheet metal and roof structures. The system then adds a BauderPIR FA flatboard insulation and a single ply membrane to complete the overlay solution.

When to specify...

The Profiled PIR Infill Overlay System is primarily intended for refurbishing profiled sheet metal roofs whilst also increasing their thermal performance, bringing the construction up to current building regulation requirements.

The PIR insulation infill boards are cut on site to ensure they match the existing sheets and can support the FA PIR. U-values are calculated using the thickness of both the PIR infill and FA PIR flatboard insulation boards.

Characteristics of the system

■□ Overlay system for upgrading thermal properties of an existing profiled sheet metal roof.
■□ Suitable for use with Thermofol (PVC) & Thermoplan (FPO) systems.
■□ Single source supply of all components.
■□ FM Approved Assemblies for Thermofol as defined on the FM online database ‘RoofNav’.
■□ Comprehensive range of guarantee packages to suit project and cover requirements.
■□ The system will bring the construction up to current building regulation requirements.
