We always try to stories with our photographs to help teach what we do, to show you, someone who doesnt do what we do, how or why we do it. Here is a great example that is very relatable as far as seeing it from the living space. In this before and after you will find a bathroom fan from the attic view. Here is how we air seal this area!
***This is a great example of the bathfan. We were not contracted to replace the venting or improve it. However we would like to point out that this fan is vented poorly. You should always use smooth bore pipe (4 inch metal duct work), with a 1/4 inch per rise or greater (NJ code), sealed with duct mastic, and insulated with a minimum of R-8 insulation.***
