✅ Breathable Eco House vs Normal Airtight House
| Topic | Normal Airtight House | Breathable Eco House (Diffusion-Open) |
|---|---|---|
| Main idea | House is sealed to stop air leaks and reduce energy loss | Walls are diffusion-open so moisture can move safely through layers |
| Airtightness | ✅ Airtight (in theory) | ✅ Airtight (still required) |
| Energy efficiency | ✅ Very good | ✅ Very good (when airtightness is done correctly) |
| Drafts / comfort | ✅ Less drafts | ✅ Less drafts + more natural indoor comfort |
| Indoor air quality | ⚠️ Depends strongly on ventilation system | ✅ More forgiving, healthier indoor climate |
| Humidity control | ⚠️ Can build up if ventilation is not perfect | ✅ Walls help regulate moisture naturally |
| Condensation risk | ⚠️ Higher risk inside construction if moisture gets trapped | ✅ Much lower risk — moisture can dry out |
| Mold & hidden damage risk | ⚠️ Higher risk (wet insulation, mold, wood rot possible) | ✅ Lower risk (better drying and moisture buffering) |
| Ventilation dependency | ❗ High — mechanical ventilation must work correctly | ✅ Still needed, but system is more forgiving |
| Feeling inside the home | “Warm, but sealed” | “Warm, fresh, natural” |
| Summer performance | ⚠️ Can overheat more easily | ✅ Better heat delay → cooler longer |
| Materials | Often synthetic (EPS, foils, sealed layers) | Eco/breathable (wood fibre, cellulose, breathable membranes) |
| Construction difficulty | Easier and more common | Requires correct detailing and materials (no shortcuts) |
