I have been building in the northeast for some time, a lot of my work is located close to the shore or right on the water. With the idea to make the outside of the houses maintenance free, other than natural white cedar shingles left to age.
I use a lot of AZEK or similar trim. When I install trim in the summer, the trim shrinks up to 1/4″ in the colder months. I have glued each joint bonded each seam, but the shrinking still occurs. Is there some way to keep this from happening or is just not the perfect science yet.
