    • What are tapered insulation wedges and what are they for?

      “Tapered wedges are angle-cut PIR elements used to create a fall on a flat roof — without screeds or loading the structure. They ensure proper drainage (water runs to the outlets instead of ponding) while also insulating the roof. It is a lightweight, fast-to-install solution designed individually around the outlet layout.”

    • What fall do tapered wedges provide?

      “A 2% fall is the standard design (in line with flat-roof requirements), but the layout is set individually — typically from about 1.5% to 8%, with counter-falls and sumps around the outlets. Based on the roof plan and outlet locations, BOKKA prepares a wedge layout design with a parts list.”

    • What is the unfaced PIR board (izoGRASS) and how does it differ from termPIR®?

      “izoGRASS® are PIR boards cut to size, without facing — BOKKA's own production. They are used in covered/ballasted flat-roof build-ups (under bitumen felt, membrane, ballast). The lack of facing means reaction-to-fire class E and λD of about 0.027 W/(m·K). It is a different product from faced termPIR® — izoGRASS is not intended for ETICS systems or as a finishing layer.”
