Log Home Packages
A Flexible Log Home System
Introducing the Woods of Woodruff precision milled and kiln-dried logs. From rustic weekend retreats to executive homes, no other type of building characterizes the natural beauty and relaxed lifestyle of our Wisconsin Northwoods like a log home.
The advantage of the Woods of Woodruff system is that kiln-drying the logs virtually eliminates the risk of the logs shrinking and twisting after construction. No more worries about calculating allowances for settling! Corners are factory notched, ensuring a weather-tight fit, and high density foam sealer between the logs prevent water and air infiltration. The result is an affordable log home that is easy to build and easy to maintain. Our system is so flexible, we can build your home from conventional home plans. Bring your plans in or contact our design staff to design your own home.

Log Profiles
Our milled logs are kiln-dried Eastern White Pine in the following sizes and shapes: 8" x 8", 6" x 8" and 6" x 6", D-log (flat on the inside and round on the outside), C-log (round on both sides), and square. The logs are Forest Stewardship Council (FSC) certified, which means they are sourced from well-managed forests, mainly within 100 miles of our sawmill.
Factory Direct Savings on Your Log Home
Bottom line—factory direct keeps your cost down. Unlike most log home manufacturers who sell their models through a network of distributors, we can offer you a better price on your log home package - factory direct. You get manufacturer support from the people who know the product best and single source accountability. And, in most cases, the lower price holds true even if shipping a considerable distance. We sell all the components that are necessary to build your log home, including windows, doors, stain chink, cabinetry, wood flooring, and roofing materials.
Flexible and Distinctive Log Home Design
Our system is so flexible, we can build your home from conventional home plans. Bring your plans in or contact our design staff to design your own home. With our in-house residential design department we can take your log home from dream to reality. Let our experienced design specialist help you design the home of your dreams

What is the insulation value of the log walls?
When shopping for your new log home, one of the first questions that you are sure to ask is, "What is the insulation value of a log?" Most sales representatives will stumble on this question even though they have heard it before. Why? There is no simple answer. First of all, for every one inch of wood between you and the outside, there is an R value of 1.5. So if you have an eight inch log, the R value will be 12. On a typical framed house the insulation in the wall will be rated at R-19. Now, this is where people become confused. How is it that a 4" wall filled with fiberglass insulation has a better R value than a solid log? The simple answer is that air is the ultimate insulator. However, an eight inch thick log is in effect the better of the two choices. Fiberglass insulation traps air in thousands of individual pockets preventing heat from conducting through your wall. If you were able to afford it, a 2x6 wall with R-30 insulation will give you almost the same benefits as an eight inch log wall. To understand this you must understand two different concepts.
R-Vlaue vs Thermal Mass
Heat will always travel from a warmer area to a cooler area by one of three ways, conduction, convection and radiation. Conduction is the direct transfer of heat through a material such as a pan on a stove. Convection is the movement of heat through the air. When air is heated it becomes lighter and less dense than the cooler air which being denser tends to sink, the currents produced by the flow of warm air up and cool air down is the basis of convection. Much the same as your oven works. Radiation is similar to convection; however, heat is transferred through the air and absorbed by another material. The rate of flow depends not only on the material but also the difference in temperature on opposing sides of the material.
First of all let’s start with R value and how it is determined. R value is based on K value. (1/k) is the Thermal Resistivity and refers to unit thickness and is defined as the reciprocal of thermal conductivity. The K value or Thermal Conductivity specifies the rate of heat transfer of a given material. If a material has a K value of 1, it means that for every 1cubic meter of material it will transfer heat at a rate of 1 watt for every degree of temperature difference between opposite faces. This is expressed as 1W/mK. The lower this value, the more resistance to heat transfer.
When you consider that fiberglass has a K value of .050 and wood has a K value of .144, why is a solid log more efficient than an insulated framed wall? This is where thermal mass comes into play. Thermal mass is a materials ability to absorb and hold heat. In building terms, thermal mass is the ability of a material to absorb heat during the day when you prefer to be cooler and then radiates this heat inside at night keeping the building at a more steady temperature. Ideal materials for thermal mass are those materials that are high density and have low thermal conductivity, which makes logs a perfect candidate. A better example may be a concrete basement that is surrounded by earth. Basements such as these are usually cool as they are not only built of thermal materials but the earth around them is also excellent thermal materials. However in the case of such a basement, this is too much of a good thing. If you were to try to keep a basement at 78 degrees, you would find that any heat source would have to work overtime to achieve this result. The reason for this is that the concrete and the earth are constantly absorbing the heat and storing it away from the area you want to heat. Like most things, too much of a good thing is bad. If a thermal material is too thin versus too thick, the heat from outside would sink right through the material and be radiated into the home. So, there is a balance to these things.
Determining your wall thickness can be calculated by your architect or even by your budget. However a good rule of thumb would be a minimum of 6" anywhere. If you live above 45 degrees north it would be a good idea to have a minimum of 8". If you live in the extreme north, such as Alaska, I would recommend at least 12" of log between you and the outside world.
On a final note, there is little doubt that log homes offer a more natural and soothing home than any man made or fabricated material. It is important that you understand the advantages of the Thermal Mass of logs if you are trying to decide between conventional construction with log siding and a real log home based R-Value insulation factors. However, regardless of your preference, none of this matters if your doors and windows are not properly installed. The largest loss of heat in any building besides the roof is around window and door jambs. Pukall Lumber has proven energy efficient systems for sealing all the openings in your home. The Design Center/Log Home Model has achieved a WI Energy Star award and is one of the few log homes in WI with such a distinction.
