Inspected a home today built in 1998 or 1999 and I’m about 90% sure this is LP siding. It was in good condition with no visible defects however I know this particular siding has been problematic.
Is this LP siding?
Here’s a little help. Some of the links are old and don’t work but it’s still a helpful site.
Yes it is. If you look closely at the knot you will see an L and a P which was their signature in those days. Newer versions dropped the knot signature.
