Prove the window won’t grow mould.
TIRS™ is forensic hygrothermal analysis of the actual window and its interface — producing the AIRAH DA07 Mould Index for health, amenity and moisture management. Modelled to ISO 15099 and validated against THERM, it’s condensation evidence your certifier can rely on.
Condensation is the 2026 frontier — and it’s misunderstood
H/F condensation compliance on glazed facades is genuinely misunderstood — by consultants as much as anyone. TIRS™ settles it with a forensic, standards-based assessment of the real detail.
The real surface temperatures
A static-state, 99th-percentile hygrothermal scan of the window and interface — where the cold spots and risk actually are, not a rule of thumb.
AIRAH DA07
The output is the DA07 Mould Index — the measure your design is assessed against for health, amenity and moisture management.
Validated vs THERM
Modelled to ISO 15099 and validated against THERM, via Verification Methods F8V1 / H4V5 — evidence your assessor can stand behind.
Independent & product-neutral. AFRC Lab is a third party. We map the method, specify the performance it must meet, train your people and verify the outcome — we don't supply, sell or endorse any product or brand. You procure systems and materials from your own suppliers; our role is to make the result defensible, whoever you buy from.
Your standard aluminium system — does it actually comply?
Condensation and mould management is now written into the NCC (F8 / H4) — not optional. Aluminium runs cold where the frame meets the glass, and that edge is exactly where condensation forms and mould takes hold. And it isn’t just a cold-climate issue — we’ve seen standard aluminium struggle right across the country, Brisbane to Melbourne. Every system is different, though, so the only way to know is to assess the real one, the way it’s actually installed.
We’ve noticed standard aluminium is struggling to comply. One thing we’ve learnt over the years: it’s far easier to prove compliance upfront than to scramble once you’re engaged. Send us your system and we’ll assess it against F8 / H4 — your first one’s free.
AFRC Lab assesses the real window and interface for condensation and mould risk (the AIRAH DA07 Mould Index) to ISO 15099, validated against THERM — independent and product-neutral. Every system is different; yours gets its own assessment.
