I have a strange question that has never come up before. I have a customer that would like vinyl batts adhered to the wall of a metal frame work shop. The original batts where simply glued with the…Continue

Timothy Renz replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?Timothy Renz replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?"I can agree that the Owens Corning product can easily be applied too thick and create a problem for the drywallers but that problem is all in the installer not with the product. Form personal experience it takes a few tries to get good at the…"
Robert H replied to Timothy Renz's discussion Indoor Humidity Levels"Something to remember is that newer high SEER AC's have a higher coil temp than the unit it replaced. This reduces the ability to dehumidify. If you compare a new A coil you will see that they are larger than old A coils. More…"
Timothy Renz replied to Caleb Simon's discussion Spray Foam and 2009 IRC codes? Your interpretation?"When we use this product we place a laminated technical data sheet in the given area and give the home owner a copy to keep with their receipt to show any one that may ask what the product is and that it does not need to be covered with a fire…"
Bob Blanchette replied to Timothy Renz's discussion Indoor Humidity Levels"Running the blower at a lower speed can help with humidity issues. A simple humidistat hooked to the "dehum" terminal on the furnace board can help."
Timothy Renz replied to Timothy Renz's discussion Indoor Humidity Levels"Thanks for the advice Bruce and Kevin,
I had a gut feeling that the HVAC system has been over sized so I asked my HVAC guy to the house to check for those issues. I also conducted a blower door test on the house and found that that there was .44…"
"Unfortunately there is some missing information here, which of course you'll have a chance to gather. I also would take a look at the basement and what the humidity levels are there. It's interesting that he gave you the RH…"
Bruce Navin replied to Timothy Renz's discussion Indoor Humidity Levels"I would look primarily at the "70% finished basement" --did they seal the CMU before putting up drywall? What about the floor? If they have a ceramic tile in the basement, efflorescence is a good indicator of moisture movement…"
Timothy Renz replied to Caleb Simon's discussion Spray Foam and 2009 IRC codes? Your interpretation?"I do not have a full cavity foaming rig, but when I do I sub the work out to a subcontractor. He carries a full cavity open cell spray foam product that is fire rated and does not need to have an ignition barrier on it. The product is…"

I am going to meet with a homeowner this after noon and he is concerned about Humidity levels in the house. This is what he has shared with me about his house so far: That sounds great. Look forward to it. I work close to our home so could meet you fairly quickly with some advanced notice. I think there are two keys with our mostly brick veneer house...the attic and basement. Today, we are currently sitting at right about 50% humidity on the first and second floors. When it got in the…See More

Timothy Renz replied to Ronald L. Stevens's discussion How to help new energy pros migrate into our new career as fresh students right out of class?"One piece of advice is to have an idea of the cost of the recommended repairs to the home you test. That is one question that all homeowners want to know. If you do plan on staying on only the audit side find some local reliable…"
Timothy Renz replied to Patrick Michaelyan's discussion Treating crawl spaces (with ductwork) when the adjacent basement ceiling is insulated."I agree with your preferred option. If the connected space is climate controlled then stopping moisture and outside air from entering is the best option. Only putting the FG batts in the ceiling of the crawl space would…"
Timothy Renz replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?"I am also a certified installer of the energy Complete System based out of St. Louis. Like many other s have said this system i great for minimizing the unwanted air flow into a home and through the insulation itself.
Very recently…"
Ed Ballard replied to Timothy Renz's discussion Vinyl batt to metal frame ware house"Timothy---------I agree with you and Bruce. the adhesive will fail. We have done similar projects with this type of building and insulation. We have drilled holes in the purlins and formed a wire grid to hold the insulation in place

Timothy Renz replied to Timothy Renz's discussion Vinyl batt to metal frame ware house"Thanks Bruce, all great points and I could not agree with you more as far as being willing to walk away form a job. If i do not feel comfortable standing behind my work and am wiling to guarantee the work, I will not do it. I have…"
