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.
The customer had been experiencing ice dams for over 30 years. Raking the roof every winter was just a part of their normal routine and they learned that taking a vacation during the winter was not possible after coming home to ice dam damage and water intrusion. Upon consideration of selling their home, they were curious to see if this long-standing problem could be resolved because they did not want to pass on the burden of ice dams to a new potential homeowner.
A home performance assessment was conducted to create a specific scope of work aimed towards preventing ice dams and improving overall home performance. It was determined that air sealing, adding insulation to the attic and ensuring proper attic ventilation was necessary. The work was performed and a final test was conducted to gather data for comparison. The overall air leakage of the home was reduced by 20%. Not only are ice dams no longer an issue, but the overall energy efficiency and comfort of the home have greatly increased. Now the homeowners feel that anyone would be lucky to live in their high performance home.
A homeowner recently remodeled but they were still experiencing high energy bills. During the first winter of the renovation, condensation in the attic was developing to the point that water was dripping into the newly remodeled areas of the home and the roof sheathing was beginning to show signs of deterioration.
Upon evaluation we found that the attic insulation had been disturbed during the renovation. The attic floor also had many gaps and penetrations from plumbing, electrical and framing components that had not been air sealed (typical for the age of the home). We also found that a whole-house humidifier was set to allow higher than recommended levels of indoor humidity during peak winter periods. We discovered that conditioned, moisture-laden air was migrating into the attic and forming frost on the underside of the roof. This migration was likely increased unintentionally due to upgrades in the home’s windows, doors and siding during the renovation.
Kinzler removed the damaged and wet insulation so that the attic floor could be properly air sealed, stopping the conditioned air from escaping into the attic and ventilation chutes were installed to allow for proper ventilation of the attic. A skim coat of spray-applied foam was installed on the entire attic floor for a complete air seal and supplemental fiberglass was installed to meet code R-values. The customer also consulted the manufacturer of the whole-house humidifier for recommended settings based on outdoor temperatures.
