Bathroom Fan Venting Oops

Today's sales call was interesting. A kneewall attic space with the usual issues. Of course, the prior contractors who came before me had interesting things to say. Let's see, "rockwool is the best..." "Fiberglass is the best..." "Foam is the best..." The poor client had information overload, so I helped contribute to it with my views on all of the insulation products. Of course HZG is a cellulose fan - however I acknowledged the benefits of the other insulation products (almost - the only benefit of rockwool is to remove skin from the body, which elicited a chuckle from the homeowner.)

None of the other contractors referenced air sealing - and they probably never will. This is a huge advantage on sales calls. This particular client had a 6" chimney chaseway in their attic. There was insulation installed on the kneewall - however it was backwards. The issue that I'm addressing in this blog is the bathroom fan venting oops. Not because it's more serious than the others, it's just been a while since I've seen it (and I'm sharing it with you...)

The gentleman decided to finish the attic space and put in a bathroom. It was done spectacularly -quality craftsmanship. However, I asked him how he vented the bathroom fan. Deer in the headlights... "What do you mean, vent it?" Egads... The ceiling was sloped and he installed a bathroom fan vent in the slope. He thought the slope was enough to vent the fan. When I slowly explained the process of moisture and venting, the light above his head went off and he asked what could be done. Fortunately, a termination kit precisely in stalled on the roof would solve the problem - however the drywalled ceiling with "moisture issue" would need to be fixed.

Again - venting must be encapsulated and moved to the outside of the building shell. Always...
