Review: This cord can serve several purposes, but was great for my engineered log cabin. While engineered logs are supposed to require chinking, eventually the logs twist out of shape and the gaskets used two decades ago begin fail. We had our logs sand blasted for new finish and the amount of sand inside proved this! This chinking helped re-establish the tightness of our seal so well, we had to crack a window to light our wood stove! Exactly what was looking for…better insulation!
Review: Using this product for the space between the patio and the house to prohibit water entering.
