Our PassiV Future Proof window (formerly branded Future-proof) has been certified as a Passive House suitable component by the Passivhaus Institut, Germany.
Our PassiV Future Proof range was specifically engineered to make ultra low-energy windows generally accessible to all. The Future Proof range provides U-values as low as 0.134 BTU/hr.ft2.F – thermal performance that, until now, was typically available to but a privileged few. Now home owners, architects and builders can surpass building requirements and make buildings future-proof for years to come. See some examples of our products on our projects page.
