Supplying high-performance windows and doors for a Passive House cottage on top of the mountain in Alcove, QC overlooking the lake

For this beautiful Passive House cottage in Alcove, Quebec, our team collaborated closely with an Ottawa-based architect to deliver timber-aluminum high-performance windows and doors that met all Passive House thermal standards with ease. Our proposal fit perfectly within the project’s budget, ensuring exceptional efficiency without compromise. Despite construction delays, InterHaus securely warehoused the order until the site was ready—demonstrating our flexibility and commitment to client timelines. The installation was carried out by the builder under our supervision service, ensuring precision and compliance with Passive House requirements. We also provided accurate rough opening dimensions and detailed installation guidelines in advance, facilitating a smooth and efficient build process from start to finish.
