Started siding
We finally decided on a siding material. Eastern white cedar shingles with 2 coats of factory applied Cabot solid stain (20 year warranty, limited of course), with home slicker 10, a Nylon mesh undercoating. Not sure how enviro. friendly this nylon mesh is but it does appear to create a good water drainage layer and airflow. I think all the old barns (and some houses) that still have their cedar shingles intact lasted because the air blew right through them. The shingles are reasonably enviro. friendly as they are sourced fairly locally (northern New Brunswick) therefore lower embodied energy and through so called sustainable harvesting. Pictures to follow.
