Which window keeps the mould out?
The frame and the edge of glass decide whether a window carries mould risk and how comfortable it feels — not just its U-value. And the climate changes the verdict. Eight sills, one glass, three zones.
Pick a climate zone.
Tap a zone on the map. Every sill carries the same glass — see the eight ranked by TIRS™ score, with the Mould Index against the NCC limit and the Outcome X surface temperature against the 12.6 °C mould threshold. Tap any sill for all five conditions.
Scores and the Mould Index are TIRS™ assessment outputs; the NCC gate is Mould Index ≤ 3.0 (equivalent to a minimum surface temperature ≥ 12.6 °C). This is an assessment result — the appointed certifying authority determines compliance.
Compare two, side by side.
Pick any two sills and read them off against each other in the selected zone — the Outcome X thermal image, the scores and the interface numbers. Same opening, same glass; only the frame changes.

All 8 systems, every zone.
TIRS™ score and Mould Index for each sill across the three zones — the selected zone is highlighted. A window that passes in Brisbane can carry real mould risk in Melbourne. Tap any cell for the detail.
