Bitumen & Heavyweight Composite Facer for PIR/PUR/XPS/Polyiso Boards
A bitumen or heavyweight composite facer direction for PIR, PUR, XPS and polyiso boards. Review composite construction, facing side, mass or reinforcement where documented, bonding or lamination, handling and board-process fit; the facer alone does not establish roofing, weather-barrier or finished-system suitability.

How this route sits inside the buyer system
Layer stack is conceptual and must be adapted to the buyer final board construction.
Bitumen / heavyweight composite facer
Project-matched composite construction for barrier and structural review.
Bonding / lamination interface
Validated with the buyer adhesive, foam or board-facing interface.
PIR/PUR/XPS/Polyiso board
Board construction and production process determine final selection.
Route review path before sampling
QCRP-R300-1000 Series is shared with S15 but this page is the Bitumen / Heavyweight route. Selection is subject to sample and board-level validation.
Buyers should review composite construction, handling, bonding or lamination and dimensional behaviour in the intended board process; route suitability depends on matched data and samples.
Models, material type and area weight need to match the selected board construction.
Document availability depends on selected route, model and construction scope.
Request-gated document status
Availability is confirmed by selected route, model, application scope and internal review.
Product Brief
Shared after the intended board application and selected route are reviewed.
Technical Data
Reviewed by selected model, construction and buyer-side application context.
Sample / Evaluation Guide
A4 samples or small rolls support material and board-level validation.
Compliance / Sustainability
Availability depends on selected route, declared scope and current verification context.
Is S16 a separate model series from S15?
No. Both use the QCRP-R300-1000 Series; they are differentiated by their structural route.
Which properties need board-level confirmation?
Barrier, puncture, tensile or tear, adhesion, dimensional stability and the selected production conditions.
