Primary residence set in the beautiful woods of Grand Marais, Minnesota. We are finding the SIP construction to be superior to any home we have owned. The ease of erecting the SIPs proved helpful when the construction of our home entered the winter months. The house is well built and gives one the feeling of being in a very quiet, sturdy structure.

Our new home is in a climate with moderately warm summers and very cold winters. In summer, it remains cool even on a hot day. On a cold winter day, the home retains heat and is very comfortable. We anticipate the annual heating costs will be lower than if we had used traditional construction. 

SIP wall thickness and core material: 6" Neopor SIP roof thickness and core material: 10" Neopor  

Saved time and labor and due to location of the house being in the woods. 

Vaulted roof with SIPs and numerous architectural beams. 

HVAC system used on the project: Heating: Dual fuel, in-floor, radiant heat. Primary heat source for the hydronic fluid is an interruptible Slant Fin Monitron electric boiler (100% efficient). The secondary source is a Navien propane boiler (95% efficient) which also serves as a secondary source of domestic hot water. Vermont Castings Encore woodburning stove with FlexBurn technology also used for heating. EcoTech air exchanger provides outside air. 

Window U Value U-25. All LED lighting, energy efficient (HE, Energy Star, etc.) appliances, efficient Sierra Pacific windows. Low VOC paints, wood floors 

Owner comment: “Everyone should build with SIPs, I don't understand why they don't, their loss (energy).”
