I've got two situations where I need help with holes in my walls.
In the laundry room, the rigid pipe dryer vent is going out through the
garage wall, then venting outside. In the winter, the laundry room is ice
cold. I've got insulation surrounding the pipe. Is there some sort of
collar I could use to not only dress this up, but help with the air
Along the same lines, I need to run a 3" pvc pipe through a wall in my
utility room for a radon system. Is there anything I could use to dress up
the entry point where the pipe is going through the wall? I hate the idea
of a pipe sticking in a wall without some sort of collar around it.
Thank you for your time.
