![]() Welcome! I know nothing about log cabin building but I want to suggest your local library for books to read. I'll probably need to adapt a lot of things for use on 4x4's, but as long as I have the theories and reasoning why each joints is the way it is, I'll be able to translate theory to my problem. Are there any websites that describes and SHOWS the different types of joints for flooring, dovetail notches, roofing, etc? If not, any good books that illustrate really well how to build a log cabin? I've read many reviews on amazon, but I'm lost as to which book is good and will give me the info I need. Perhaps glue them in place?Īs you can see, the whole process of joinery / setting the logs is foggy to me. Maybe add a long dowel rod into all of them or do a thong/groove type thing on each one (ouch, time consuming.but if we have too). I was also thinking that I'd forgo the chinking and pile the logs one over the other. I use 2 sleeping pads one over th eother when I winter camp in a tent and they have an R-value of 2-3 each. ![]() So, for a 4x4 (3.5"), it would almost give us R-5.which isn't that bad. I read (on this forum I think?) that for every inch of wood, it gives approx an R-value of 1.41. Also, this is why 6圆 or bigger beams are out of the question. So, if we can use mecanial means to gain strength (dovetail joint) vs putting in 2-3 nails, we'll go for it. Our budget is very limited, so the lower the better. It then dawned on me to try and build a log cabin style camp with 4x4x12 dimensional lumber using dovetail notches. After adding all the numbers, it seems to add up quite quickly. Well, I started day dreaming about a little hunting camp lately (12x12 with sleeping loft). Small Cabin Forum / Cabin Construction / 12x12 Log cabin with ing 4x4's? Such climates generally exist in the Earth's temperate zones between the 15th and 40th parallels.- Forums - Register/Sign Up - Reply - Search - Statistics. This generally increases the apparent R-value of a log by 0.1 per inch of thickness in mild, sunny climates that have a substantial temperature swing from day to night. Logs act like "thermal batteries" and can, under the right circumstances, store heat during the day and gradually release it at night. Because of the log's heat storage capability, its large mass may result in better overall energy efficiency in some climates than in others. The extent a log building interacts with its surroundings depends greatly on the climate. ![]() Your state energy office may be able to provide information on energy codes recommended or enforced in your state. To find out the log building code standards for your area, contact your city or county building code officials. Based only on this, log walls do not satisfy most building code energy standards. Ignoring the benefits of the thermal mass, a 6-inch (15.24 cm) softwood log wall has a clear-wall (a wall without windows or doors) R-value of just over 8.Ĭompared to a conventional wood stud wall (3½ inches (8.89 cm) of insulation, sheathing, and wallboard, for a total of about R-14) the log wall is apparently a far inferior insulation system. The R-value for wood ranges between 1.41 per inch (2.54 cm) for most softwoods and 0.71 for most hardwoods. In a solid log wall, the logs provide both structure and insulation. A material’s thermal resistance or resistance to heat flow is measured by its R-value.
