Does bathroom insulation need a vapor barrier?

• <div><p>Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.</p></div>

Shawn was great. He fixed our vintage door bell. It was a tubular doorbell that chimes with pipes. It was an old original from the 70â s and no parts were available. Shawn worked his magic and itâ s working great. Love my doorbell. Thanks to Shawn. Highly recommend him.

Very polite and courteous crew that was actually a bit early. When does that happen? These days you're lucky if they show up on the day they scheduled! Materials and installation were very high quality as good as I've ever seen. Very impressed in everyway from the salesperson to the installers...

I appreciated Mad City Windows quick response time to questions. They had great suggestions for replacing my windows and the installation took only one day. I have noticed a drop in my electricity bill too, which is always a plus!

Nick, was the plumber that installed the water heater and recirculating pump for us. He was knowledgeable, efficient, neat, and courteous. The project had no surprises and was accomplished for the bid price.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures.
