In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
My boiler is in a very small closet in a finished basement. I added a direct air intake to the boiler from outside and want to replace the closet door. I have the following questions:
- If I install a wood door, does it need metal flashing on the inside by code?
- what door vent products are recommended to reduce noise?
Thanks in advance for your help.
