Kinzler was hired by Hammerback Remodeling to insulate a custom lake home North of Bemidji, MN. Kinzler insulated the walls with five and a half inches of open-cell spray foam. Kinzler installed a hybrid insulation system in the attic, starting with three inches of open cell spray foam, and covered it with R-40 of blown fiberglass insulation to achieve an R-50 assembly. This created a very efficient and quiet home for our customer.
Because of the “bonus truss” roof system, the customer needed to install a roof venting system and spray foam in the roof area. This also allowed the customer to place heating and air conditioning ducts in the conditioned attic space.
Kinzler installed open cell spray foam in the garage area bonus room portion of the 8,000+ square foot home in -30 degree weather. The customer originally wanted to used closed cell spray foam, but couldn’t because of the temperatures. Kinzler worked with a general contractor to design an efficient insulation system that could be installed in sub-zero temperatures without compromising the quality. It was decided that the best solution would be to do the bonus room in open cell spray foam, initially, and to come back the next fall to replace with the closed cell spray foam that they requested but couldn’t install because of the temperatures. Additionally, we put open and closed cell spray foam insulation in the attic with R60 blown-in fiberglass over the foam.
Due to a vaulted roof system and mechanical ducts located in the attic space, Kinzler installed a polystyrene vent system and twelve inches of open-cell spray foam. To improve the overall performance, we also installed five and a half inches of open cell spray foam in the exterior walls. The result was an extremely well-insulated and quiet retirement home for the customer.
One of the prime examples of passive houses in the United States is the Waldsee BioHaus Environmental Living Center at the German Language Village in Bemidji, Minnesota. Constructed in 2005-2006, Waldsee BioHaus is the first Florida + biohaus1-22-09 088 officially certified Passivhaus on this continent representing modern German architecture and sustainable building design. The BioHaus is both residence and environmental learning center for language enthusiasts who come to Waldsee, not only during our many summer programs, but also year round, to learn about German culture, the environment, renewable energy systems, and sustainable living while being immersed in the German language.
For a couple of years Go-Devil Boats, based in Baton Rouge, Louisiana, had been facing issues with their existing insulation which was falling and causing a mess. High-R Metal Building Solutions came to the table with a cost-effective solution to solve their insulation issue and improve the aesthetics of their facility.
With over 30,000 square feet of area to install, High-R called upon Kinzler Construction Services of Ames, Iowa and Garland and Jones Insulating of Tyler, Texas to attack this project with a high level of experience and professionalism. While installing the new RetroPan system, the High-R crews worked safely around the employees of Go-Devil Boats on a daily basis, and kept up the production rates of both companies.
The project was completed in approximately 5 weeks, coming in on schedule and budget, without any major setbacks. With a satisfied customer and a great looking facility, this is just another success story for the High-R team.
Kinzler was hired to do excavationless foundation insulation at a home in Minneapolis. This home was built in 1907 and was recently purchased by a new homeowner that is in the process of turning it into a net-zero home, pursuing Green Star certification. The foundation insulation is one of the first items in this big project.
This is the third home where the excavationless foundation insulation procedure has been done. The procedure originally came out of a U.S. Department of Energy field study and involves using a Hydrovac truck to vacuum out a 4” trench of dirt down to the footings around the outside of a home. After that, 1.5” of rigid foam board is installed against the dirt and the remaining 2.5” of the cavity is filled with a special blend spray foam that was made specifically for this application.
The excavationless procedure works well on existing homes. The alternative approach is to use an excavator to dig out the foundation and insulate it using a different strategy. This alternative could take longer, be more expensive and will cause more damage to grass and landscaping.
In the next few months, when the home is ready, we will return and insulate the rest of the foundation above grade so there is a seamless transition between the exterior wall and the foundation insulation. Kinzler will also be insulating other areas of the home including the walls and ceilings. We are excited to be part of such an innovative project and is happy that the homeowner will now have a more comfortable, durable and energy-efficient home.
