Shepherd’s Gardens Heritage Opts for a Spray Foam Solution
By Alan AnnisUpscale senior living at its finest; that’s Shepherd’s Gardens Heritage. Spacious balconies, expansive windows, and social amenities like a theatre room, dining room, and coffee shop make Shepherd’s Gardens Heritage a virtual paradise for its residents. This 15-story, 59,900-square-foot facility located in Edmonton, Alberta is conveniently located near grocery stores, banks, and other necessities.
Residents also have access to the Light Rail Transit (LRT) and underground parking giving them the freedom to go wherever they want, whenever they want.
This new facility was created from modular panels that were pre-assembled off-site as large panels and then delivered to the facility construction site to be installed on the structure. This allowed for the construction of the building to take place at multiple locations and sped up the time it took to complete the new building. The panels averaged 30’ by 15’ in size and were constructed of 2”x 6” metal studs with 5/8” gypsum wallboard. The panels came to the site with 4” of Styrofoam on the outside.
For this project, it was determined by the building owner that spray foam would be the best insulation solution. Smart Choice Spray Foam & Coatings was chosen as the spray foam contractor due to the General Contractor’s prior working relationship with them. Smart Choice has a reputation for efficiency and getting the job done right the first time.
Smart Choice are true professionals when it comes to best practices in foam installation. Starting with substrate preparation, it’s important to verify adhesion before beginning. Testing on all of the substrates, including the exterior sheathing, was done prior to application. The foam had excellent adhesion and it was determined that no primer was needed. Each morning, the sheathing board was checked for moisture and wiped down thoroughly before the foam installation. This was required because the application was taking place in the late Fall of 2015, when condensation and frost were prevalent.
After the pre-assembled wall panels were installed, the Smart Choice crew would apply the 2” of SWD’s Quik-Shield 112 and seal the seams between panels. The spray pattern was adjusted using a distance of about 18” from the substrate, to allow the applicator to cover an adequate area per pass. The interior drywall was fastened to the assembly after the panels were sealed.
For a large portion of the project, the building wasn’t dried in. There were vast temperature differences between floors and wind tunnels were created that would cool the entire place significantly. In order to mitigate this, the spray crew had to wait until the rest of the construction crews had finished enough of the building so they could heat sections, and then they could only spray during the day.
The weather created the most difficulties for the team. Initially, they tried to work at night, to remove the concern with other trades working on site, but the humidity made that impossible. The temperatures at night fell to around -6°C (21°F), and the condensation and frost that formed on the studs and wallboard at night made it useless to try and spray. If one were to try and spray with the moisture present on the substrate, this would lead to popping of the foam, in which case the foam would need to be removed and reapplied. This would result in wasted time and materials.
In the morning, the spray crew would wipe down the substrate to remove moisture before spraying. Having to wait caused the project to take extra time, but it was worth it in order to make sure the job was done right.
Spraying the entire 59,900-square-foot. building took five months, on and off, and used 30,000 lbs. of closed-cell foam. The facility is scheduled to be ready for move-in during the Summer of 2016.
Optimum living comfort was at the top of the building owner’s goals. However, it was also important that the new building be extremely energy efficient, in order to offset the rising costs of heating and cooling. Just as significant was the clean and healthier environment provided by spray foam insulation’s seamless air barrier. The choice of spray foam insulation will help create an atmosphere free from airborne pollutants, allergens, and dust. Residents will be able to enjoy their golden years in comfort, without the detrimental effects of poor indoor air quality. Furthermore, the building owner would be able to save up to 40% on their energy costs.
