BauderModel Profiled PIR -Infill Overlay System

SHARE

The Profiled PIR Infill Overlay 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 PIR FA. U-values are calculated using the thickness of both the PIR infill and PIR FA flatboard insulation boards.

Plus points
  • 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’.
  • A comprehensive range of guarantee packages to suit project and cover requirements.
  • The system will bring the construction up to current building regulation requirements.
Assessments and verifications
  • BBA Certificate 06/4354 for Thermofol and 04/4120 for Thermoplan:
    Fire classification BROOF(t4) to BS EN 13501-5 tested to TS 1187 test 4 for external fire exposure on defined permutations of product build up.
    Fire properties – membranes deemed “unrestricted” in certain circumstances as categorised in the BBA certificate.
    Service life > 30 years for a Thermoplan system and >35 years for Thermofol.
  • EPD Certification:
    Our membranes and insulations have recognised environmental product declarations (EPD).
  • Benefits:
    Cost-effective compared to stripping and renewing waterproofing.
    Different thicknesses of insulation are available to deliver U-value required by the project.
    Lightweight solution (circa 6kg/m2 for 140mm PIR with single ply overlay).
    Minimal interruption to the internal workings of the building.
