Roxborough Park

The Roxborough Park CHH in Hamilton, ON is a 10-storey affordable housing community designed to the Passive House standard.  The new building is currently under construction with a completion date of early 2022.

Architectural Rendering of the Roxborough Park CHH

Roxborough Park CHH is built with insulated pre-cast concrete wall panels manufactured by Stubbe’s Precast. Stubbe’s Precast specializes in total precast structures, including supplying and installing fenestration into their wall panels, providing a fully enclosed structure upon erection.

Innotech manufactured our Passive House International (PHI) certified Defender 88PH windows for the project. Prior to installing our windows into the insulated pre-cast concrete wall panels, Stubbe’s Precast and RDH Building Science conducted diagnostic testing on two different installations to determine the best installation to achieve the desired air-water-structural performance.

Erection of the concrete wall panels started in mid-July with an estimated completion of October (of the same year!).
