Insulated logs: End view of an 8x12 D-log with {4"} of EPS insulation. This log averages an R20.
We have developed an insulated log to meet any construction requirements. These logs work equally well to keep the cold out or the heat out. We offer the only fully insulated stacked log available. Our normal insulation is an "EPS" foam with an average R5 per inch. An optional "EPU" foam is available that meets an R7 per inch. The insulation is built into the log as the product is laminated. Our insulated logs erect the same as our whole timber logs. The log shown is our 8x12 D-log, but an insulated core option is available in any of our log profiles.
