Sainte-Germaine-Cousin is a project for the community. Located in Quebec, the church of Ste-Germaine-Cousin has come a long way, overcoming an asbestos closure in 2005.
Today, the revitalized church building stands central with a new addition, a curvy, s- shaped structure, of affordable housing with 126 affordable (PAPA type) units and intermediate housing for seniors.
Asbestos within Ste-Germaine Cousin Church presented a considerable financial challenge. After the closure of the church building, it was 7 years later in which construction began with asbestos removal and groundwork for the new addition. However, perseverance has proven successful, providing an exceptional building of great heritage value.
Steel is the most popular framing material for non-residential buildings in the US. As the AISC’s slogan goes, “There is always a solution in steel.” It is sustainable and readily available, strong in both compression and tension, and allows acceleration of project schedules making it a cost effective construction option.
If you are familiar with Schock Isokorb® you may associate it with products that limit thermal bridging in the wall portion of the building envelope in such areas as balconies or canopies. These solutions provide a continuous insulation layer in the vertical plane of the wall. As we look at the building envelope in a holistic approach, we can focus on other problematic areas that can be resolved with additional Isokorb® products.
Parapet walls, much like balconies, are thermal bridges that allow conductive materials to transfer energy through the thermal barrier. The two differ, as balconies are typically added as an aesthetic, giving the appearance of an extended living space within a unit, yet parapet walls are designed as part of the structural integrity of the building.
Parapet walls are designed to resist variable wind pressure differences, protecting mechanical units and other roof assemblies mounted on top of buildings. As an integral part of the building structure, parapets can prove problematic in many forms, such as: lateral failure, membrane failure, water intrusion, and improper water drainage. Therefore, when considering all of these possible setbacks, continuity of thermal insulation may be a secondary thought. The current, traditional practice to remedy such problems is to wrap the parapet with insulation. However, this application could become complicated in areas where the parapet wall is adhered to insulation, and the insulation is adhered to the roofing membrane.
As Yogi Berra once said, “In theory, there is no difference between theory and practice. In practice, there is.”

Building performance codes have become more rigorous in Canada, especially in the Ontario Province with SB-10 standards. Architects are looking for more options to meet these code requisites, and projects in Ottawa such as St. Patrick’s, Tweedsmuir and Cathedral Hill are setting the bar.
These three projects are currently in construction in Ottawa, and all share the similarity of using Isokorb concrete thermal breaks, yet they are distinctive in building design and purpose. The St. Patrick’s home is a short and long term care facility, Tweedsmuir a low rise development in the Westboro neighborhood, and Cathedral Hill is a high rise condo/apartment building in downtown Ottawa.
During last month’s American Institute of Architects (AIA) tradeshow, a noteworthy study was released, which compares the thermal performance and whole energy impact of concrete balconies. The research was completed by Morrison Hershfield, a leader in building physics, who also completed the ASHRAE 1365-RP, Thermal Performance of Building Envelope Details.
Every balcony, penetrating the building envelope with scenic window walls, has three main issues to be addressed: thermal bridging, forces at the balcony/slab connection, and water intrusion. The Schöck Isokorb® Type CM is the effective solution for these obstacles, reducing the heat flow from the inside to the outside, while also conserving full structural integrity.
On February 5th and 6th Alex Krenzcik and myself had the opportunity to speak at two events in the Denver, Co area. The first day the Building Enclosure Council (BEC) of Denver hosted the event to the crowd of over sixty attendees in which we presented our accredited AIA presentation on Structural Thermal Breaks for Balconies, Canopies and Beams. In attendance were architects, engineers, façade consultants, and other various professionals in the building industry. I was really impressed by the attendance and interest the BEC displayed on limiting thermal bridging problems that are becoming more realized. There was a lot of dialogue throughout the presentation and still currently on how to integrate Isokorb® into varied projects.
My name is Adam Kimble, born and raised in the suburbs of New Orleans, LA. Explored the world in previous business roles only to land back in Louisiana. Now, I have the great opportunity to start a new adventure in the great city of Chicago, IL, where I will manage Midwest sales for Schӧck USA Inc.
With a degree in Civil Engineering and Business Administration, I have been afforded the honor to work for multiple international companies in various capacities from business development to director of operations.
Now I have the special honor of joining Schӧck to introduce Isokorb® in the U.S.A. which will provide high performance solutions to the long outstanding problem of thermal bridges at balconies and other external wall projections. … read more
