Use Pro Clima airtightness products to achieve Passivhaus airtightness below 0.6 air changes per hour (ach). Making a building more airtight saves energy and reduces damage to the building structure from uncontrolled water vapour penetration into the building fabric. Pro Clima products have been tested and approved by the Sentinel-Haus® Institute to meet their stringent standards for healthy buildings with good quality indoor air.
Passivhaus Store mostly ships direct from supplier to you to minimise transport, reduce lead-in time and avoid costly double handling of goods. If your order contains products despatched from more than one source, our delivery cost calculator will add up each delivery charge to give you a total delivery cost. Note that our policy is simply to pass on the cost of delivery to you, not to use delivery charges to make hidden profits.
