Passive Purple: Tested & Certified
Passive Purple and the wider Intelligent Membranes range are among the most thoroughly tested liquid-applied coatings on the market — verified to both North American (ASTM / ICC-ES) and European (EN) standards, with Passivhaus certification, BBA and Kiwa approvals, European Technical Assessments and published Environmental Product Declarations. Every result below comes from an independent, accredited laboratory.
Passive Purple — performance at a glance
| Performance | Result | Tested to |
|---|---|---|
| Indoor-air emissions | French A+ — very low emissions (the cleanest band) | EN 16516 (Normec) |
| Low-emission class | Finnish M1 — free from VOCs & formaldehyde | RTS / VTT |
| Air barrier material | 0.02 L/s·m² at 75 Pa | ASTM E2178 · ICC-ES ESR-4715 |
| Airtightness — Passivhaus (incl. connections) | Class A (phA) — 0.02 m³/h·m² at 50 Pa | EN 12114 (Passive House Institute) |
| Reaction to fire | Class A (ASTM, Flame Spread 0) · Euroclass C-s1,d0 (EN); B-s1,d0 with FRED | ASTM E84 · EN 13501-1 |
| Watertight | PASS — seamless, no joints | EN 14891 |
| Vapour control | Intelligent VCL — Sd ~0.8–40 m | EN ISO 12572 |
| Solar reflectance | SRI 52 — reflects ~45% of solar energy | ASTM E1980 |
| Radon barrier | Diffusion coefficient D = 3.3 × 10⁻¹² m²/s | ISO/TS 11665-13 |
| Methane / ground-gas barrier | Low, verified permeability | ISO 15105 |
| Mould & fungal resistance | 10/10 — no defacement; rating 0 (no growth) | ASTM D3273 & ASTM G21 |
| Adhesion (pull-off) | Steel 2.7, CLT 1.83, gypsum 1.6, brick 1.5 N/mm² — the bond beats the substrate | EN ISO 4624 |
| Tensile strength & elongation | Flexible & crack-bridging — ~219–350% elongation | EN 12311-1 |
| Environmental impact | Published EPD — 2.38 kg CO₂e/m² (A1) | EN 15804 / ISO 14025 |
Note: ASTM and EN grade reaction to fire on different scales — Passive Purple is Class A to ASTM E84 and Euroclass C-s1,d0 to EN 13501-1; the Passive Purple + FRED system reaches B-s1,d0. Airtight White is the same formulation as Passive Purple, so every result applies to it too.
Code compliance & certification
- French A+ & Finnish M1 — the two leading European low-emission / indoor-air-quality credentials.
- Passivhaus certified — Passive House Institute Class A airtightness (EN 12114).
- ICC-ES ESR-4715 — evaluated against the 2021/2018/2015 IBC, IRC and IECC (with a City of Los Angeles supplement).
- BBA approved — independent UK Agrément certification for building-control confidence.
- Kiwa BDA Agrément (Passive Purple External) and European Technical Assessments ETA-23/0378 (Poseidon) and ETA-25/0471 (The GOAT).
- Environmental Product Declarations — third-party verified life-cycle data to EN 15804.
The wider range — also independently tested
Passive Purple External — fire-rated Euroclass B-s1,d0 (EN 13501-1) and ASTM E84 Class A; watertight Class W1 (EN 13859-2) yet vapour-open (Sd ≈ 0.6 m); crack-bridging A3/A4; CO₂ barrier C1; UK Kiwa BDA Agrément; Passive House component (phB).
Poseidon (bathroom & wetroom waterproofing) — ETA-23/0378 (CE), watertight and crack-bridging to EN 14891, tile-adhesive bond retained after water, heat and chlorinated water; US ANSI A118.10 & A118.12; 25-year working life.
The GOAT (liquid roof & balcony waterproofing) — ETA-25/0471 (CE, 25-year working life), external fire BROOF(t1), watertight at 150 kPa, crack-bridging 1.15–1.84 mm, ~344% elongation, and an 83% solar-reflectance cool-roof white (SRI ~104).

Tested both sides of the Atlantic — suitable worldwide
Because the range is verified to both ASTM (North America) and EN (Europe) standards — alongside Passivhaus, BBA, Kiwa, ETAs and published EPDs — specifiers can rely on one product family and one evidence base wherever they build.
