"Removing drawers in vanities allows access to holes that will be invisible when the drawer is replaced.
There is a fantastic road barrier repair material that is sticky on one side. Using a heat gun it fuses to the barrier.…"
"Here are a couple of things to remember when measuring zonalpressures. First is that you want tomeasure the change in pressure caused by the Blower Door, so you will need torecord a baseline attic to outside pressure. Secondly zonal…"
"Zach - those are some good questions and I am going to relate what they taught here in a DOE based Weatherization course & some of my own experiences (non DOE weatherization). For more info on DOE & Mobile Homes I suggest you check out this…"
We have been duct sealing manufactured/mobile homes for years and have had great success. We are getting more and more requests to perform whole house air sealing in these homes. I find that newer homes are already tight, and the older homes, well it seems we are just moving the leaks around. With duct sealing we can almost always make significant reducitons, but reducing house infiltration has been much more challenging. Much of the challenge is that the actualy air barrier in the floor and…See More
"If I am understanding this correctly when the house is at 50Pa relative to outside and the attic is at 2Pa relative to outside then there is not much connection between those two zones. The 2Pa in the attic could even be due to stack. Sounds like…"
I got into a discussion with a college the other day about testing the attic connection to the house. When the house is depressurized to -50pa wrt outside, and the attic wrt house is -49pa, isn’t the attic more “outside” then “inside”? When the house was depressurized to -50pa I also looked at the attic wrt outside, and got just -2pa. My understanding is that if the Blower Door is putting -50pa on the house interior, and the attic only goes -2pa wrt the outside, the ceiling is pretty darn…See More
A hammer and a saw used to be the key tools for home contractors. Today, the best-in-breed also use high-tech equipment while performing a professional energy audit or verifying that construction has been done correctly.
"Does anyone have any good talking points for home owners that believe in the "buildings should breath" comment. I commonly use the "built it tight ventilate right" line. I also try and bring up the subject of "controlled…"
"We have had good success using rigid and one part foam to get those darn exterior wall top plates. Two part foam can be cost prohibitive. We use a fireblock foam with a dispensing gun that has a 3ft barrel. The long barrel gets out to those tight…"
Hey Zach, I like the "built it tight ventilate right" line, but I would add and the "IAQ will be outta site!" We spend so much time on build it tight syndrome, that we forget about materials and IAQ...
How much particle board, OSB, toxic glues and caulking does it take before we really understand the IAQ issues that we add with efficiency measures?
