Seal or not to seal? What to do with the cracks in your logs.

It is virtually impossible to prevent logs from developing cracks and checks as they age and dry. That's because as a large piece of wood seasons, mechanical stresses build up until the surface stress becomes so great that the wood cracks. We call these stress cracks "checks."

Do checks need to be sealed? Depends upon the depth and direction of the checks. Upward facing checks can collect water increasing the interior moisture content of the log. If they continue to collect water and the wood remains damp, they can eventually result in internal wood decay as well as provide nesting sites for carpenter ants and other insects. It is not necessary to seal checks on the bottom half of round logs since they do not collect water. For a uniform appearance of your home, you may want to seal them as well. It is not usually necessary to seal checks or fissures that are less than 1/4" wide since they cannot accumulate that much water.

The Joy of Color

Accent the Natural Beauty of Wood

Staining your log home is a humbler art. Whereas paint transforms the color of a surface, leaving no trace of its previous hue, stain is typically used to accent the natural beauty of wood. Its purpose is to bring out the best in what's already there. Semi-transparent stains from Perma-Chink Systems are designed to let the beauty of the wood shine through and to add a colorful twist to your interior or exterior.

Thermal Efficiency of Log Chink Joints

In today's economy energy efficiency is a subject that most people are aware of including log home owners and those people contemplating the purchase of a log home. With this in mind, we occasionally get asked about the R-value of our chinking and/or backing materials since many people assume that they provide some insulation value to the exterior walls. In point of fact, neither the Perma-Chink nor the backing material contributes any significant insulation value to a wall. What they do is eliminate outside air infiltration into the home. This has a much greater impact on the overall energy efficiency of a home than adding a minor amount of insulation to a wall.

Understanding Mill Glaze

Although there is some controversy regarding its cause, the most commonly held theory about the formation of mill glaze is that it is created on logs, siding and trim by heat and mechanical compression generated during a high speed milling process. The combination of compressed wood fibers and high temperatures that melt the sugars, cellulose, and other water-soluble extractives present in the wood end up forming a surface glaze.
