If your home was built in the 90s, specifically in the years 1990-1996, chances are you have LP Inner-Seal Siding. To be sure, you can take a close look at your siding and find an LP in the knot pattern. This means that if you inspect your existing siding and locate a knot on a panel, you’ll be able to trace a very subtle “L” and “P” in the knot’s lines.
