Katahdin Cedar Log Homes Introduces R-23 Energy Envelope System November 13, 2008

Increases Cedar Log Wall Energy Efficiency by 156%

Katahdin Cedar Log Homes extends its corporate philosophy of reduced energy consumption by introducing its new R-23 Energy Envelope System. The insulation system increases the R-value of exterior cedar log walls by 156%. The insulation system was developed to be able to meet or exceed new efficiency codes nationwide and qualify for green construction ratings without modifications.

"We've had increased demand for an enhanced insulation system for our already efficient cedar log homes," said David Gordon, president of Katahdin Cedar Log Homes. "Our design team has developed a unique system to enhance the natural high R-value of cedar logs. The Energy Envelope System offers a continuous insulation 'envelope' that keeps warm air inside in the winter and outside during the summer."

How does it work?

Katahdin's log homes are manufactured from Northern White Cedar, which naturally resists heat flow through its wood, referred to as the "R-value." The higher the R-value number, the more resistant the material is to letting heat transfer through. For many years, Katahdin has offered an insulation package that increased the R-value of their exterior walls by 56%, without losing the natural look and feel of a log wall. The new R-23 Energy Envelope System increases the log wall R-value by 156%, providing immediate energy savings, while maintaining the rustic log appearance.

The R-23 Energy Envelope is constructed from the log wall exterior toward the interior. A 1-1/2 inch layer of foil-faced rigid insulation is applied to the interior of the log wall. Then, an insulating 3/4–inch layer of dead air space is created by applying thin strips of strapping to the inside surface of the rigid insulation. Then the interior tongue and groove cedar, shaped to either a flat or round profile, is applied. The R-23 Energy Envelope has the extra benefit of allowing for easy electrical wiring that can save a homeowner significant wiring expense.

Superior Continuous Insulation

The R-23 Energy Envelope System outperforms conventional framed construction with two-by-sixes and fiberglass insulation, because it offers continuous insulation. A conventionally constructed wall conducts heat in and out through the two-by-sixes that become "thermal bridges" between the interior and exterior of a house. The two-by-sixes have a much lower R-value than the fiberglass insulation inserted into the spaces between the framing. With the Energy Envelope System, the entire log wall is covered by rigid insulation and thus provides an unbroken barrier in the exterior wall insulation.

Katahdin combines the R-23 Energy Envelope with high R-value, vented "double roofs," efficient Anderson Windows and Therma-Tru Doors to complete the exterior barrier to the elements. According to Gordon, "With the R-23 Energy Envelope System, Katahdin home buyers will find themselves prepared to meet or exceed most energy challenges thrown their way."

Founded in 1973 by Foster Gordon and two associates, Katahdin Cedar Log Homes is one of the largest log home manufacturers in the U.S. and is the largest processor of Northern White Cedar in the world. David Gordon continues his father's legacy by providing high quality, cedar log homes at affordable prices. Based in Oakfield, Maine, Katahdin Cedar Log Homes has more than 80 employees.
