Passive Purple: Tested & Certified
Passive Purple and the wider Intelligent Membranes range are among the most thoroughly tested liquid-applied coatings on the market — tested to both North American (ASTM) 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 |
| 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 |
| Vapor 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 |
| Mold & 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).
- Independently tested to ASTM E2178 and ASTM E84 — air barrier material (0.02 L/s·m² at 75 Pa) and Class A surface burning. In the US, code acceptance is through the test reports, submitted to the code official; ask us for copies.
- 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 vapor-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).
