IKO Permatec LI
IKO’s flagship hot melt: a monolithic hot-applied compound of refined bitumen and synthetic rubbers, supplied as 12 kg fully-dispersible blocks with a zero-waste wrapper, for inverted roofs and podium decks. Anti-Root variant available; BBA approved; marketed as lasting the design life of the building.

Carbon and evidence
Product Evidence
Evidence currently held for the IKO product record.
Recorded Carbon Result
A1–A3 GWP-total per tonne of Permatec LI compound, per EPD Hub HUB-1377. Includes −172 of temporarily stored biogenic carbon largely re-emitted in later modules — GWP-fossil for the same unit is 325. Per tonne of compound, not per m² of roof.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

Covers Permatec LI and LI Anti-Root (stated GWP-fossil variation <1.1%). Declared per tonne of compound — coverage varies with application thickness, so no per-m² figure exists and none is derived. Biogenic caveat: GWP-total (154) sits below GWP-fossil (325) because −172 kgCO2e/t of biogenic carbon is booked into A1-A3 and largely re-emitted in A5 and C — the A1-A3 total benefits from temporary biogenic storage.
