Project Profile. Home Performance

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.

Project Profile. Retrofit

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. 

 

Project Profile. HIGH-R Metal Building Insulation

Marion, North Dakota

Winters in the upper Midwest can be unpredictable which can present a challenge when insulating steel buildings.  A-Line Builders of Fargo was selected as the general contractor and steel building erector for this project and selected us as the subcontractor to complete the insulation scope of this 45,000 ft. metal building.  With winter quickly approaching traditional insulation methods were not ideal so A-Line and Kinzler worked together to set a schedule to get the structure dried out so that we could insulate the buidling from the inside.  Insulating the building from the inside once the structure was dry saved substantial downtime that snow, rain, or ice could have caused.  High-R Metal Building Insulation was installed after filling any condensation prone areas with blown fiberglass.  Then, Kinzler spray foamed around windows, doors, eaves, and gable ends to properly air seal this space.  Since purlin depths ranged from 10″-12″ we were able to achieve R values of R-40 on the ceilings and R-30 on the walls.  A big thanks to A-Line Builders of Fargo for allowing us to help you on this project.  For more information on HIGH-R, visit www.high-r.com

Project Profile. Closed Cell Spray foam

Minneapolis, MN

This homeowner has a story and a half home that was suffering from ice dams, water intrusion, comfort issues, and high energy bills. A home performance assessment was conducted to determine the “lowest hanging fruit” for resolving all of their issues. The home performance assessment revealed that the side attics, slants, and upper flat attic area were experiencing a lot of air leakage and had very low levels of insulation. Proper attic ventilation was a challenge based on the design and construction of the home. In order to gain access to the inaccessible attic areas, roof decking was removed and closed cell spray foam was installed from the exterior. The roof was re-decked and a secondary roof deck was iinstalled over 1″ sleepers providing continuous roof ventilation. The end result created an air tight, well insulated and well ventilated roof system. Another test was performed after the retrofit was completed and revealed that the total air leakage of the home was reduced by 33%. The scope of work completed will not only prevent ice dams, but also improves comfort and efficiency which reduces energy bills.
