Welcome to Northern Built, where we discuss building science, construction techniques, and energy for homes built in a cold climate.
Condensation in walls
Something we run into on occasion is condensation on the interior side of wall sheathing during the winter months. In this project, we had an elevated humidity level, missing continuous exterior insulation, and no vapor retarder. Interior moisture easily moved through the fibrous insulation and condensed on the interior side of the wall sheathing. When we removed the insulation, we found it frozen to the sheathing.

Code Minimum House-Blower Door Testing
Переглядів 1 тис.21 день тому
This was a new build I was involved with back in 2020. We began blower door testing before windows and doors were installed. I decided to see how many 2.5-inch holes it would take to bring the home from 0.55 ACH50 to 3 ACH50. As it turned out, it took quite a few.

Finding air leaks in homes has traditionally been done using a tool that produces a pressure differential, better known as a blower door test. This new tool uses ultrasonic waves to find building encloser deficiencies.
Testing the packaging for an Andersen window

My visit to Andersen included watching the ASTM D999 test, Standard Methods for Vibration Testing of Shipping Containers. These containers include the cardboard packaging used by Andersen.
Structural testing of an Andersen patio door

The ASTM E123 is a test where windows and doors are tested for structural integrity using cyclic or varying pressures to simulate wind loading of the unit. Amazing how much deflection of larger patio doors can occur during this test.
Andersen Windows and Doors Impact Test Part 2

Part 2 of my recent trip to Andersen Windows and Doors Garofalo Center for Research, Development, and Innovation. Continuation of the ASTM E1886 test, exposing the window damage to cyclic pressure differentials. To pass the test, the damaged glass must remain inside the window frame.

I recently had the opportunity to visit Andersen Windows and Doors Garofalo Center for Research, Development, and Innovation where I watched a 2x4 get launched into a window designed to handle hurricane force winds and flying debris. This test is called ASTM E1886, Standard Test Method for Performance of Exterior Windows, Curtain Walls, Doors, and Impact Protective Systems Impacted by Missile(s...
Tape Testing on Interior Membranes

A quick test to see how a standard interior air sealing tape compares to Siga's Rissan tape. In the video, I referred to Siga's Majrex product as Majvest, which is an exterior WRB. My appologies.

Just a tip, when you export and upload them, use the vertical video formats. The way it's done here makes a very small image. Thanks for sharing!
Was that a leak? How did you fix it?
Great demonstration! Awful code minimum 😂
Great video!!! Thanks for sharing.
And what about devices that generate heat…. hmmm.
Hopefully any device drawing high levels of current to produce enough heat to cause damage to a plastic electrical box trips the circuit breaker first. All electrical boxes are required to be UL listed for the purpose, meaning 3rd party testing and verification.
I learned a lot very valuable information thank you.
That’s not polystyrene, it’s polyisocyanurate. It’s an open cell fiber glass foam .
No, it is XPS, the yellow color is similar to Polyiso and the dirt stuck to the one side makes it look like it has some sort of facer, but it is XPS.
It’s open cell. It absorbs water wherever it’s at.
Yes let a bag of open cell shaving sit in the rain then try to move it😂 it’s goes from like 40lbs to 500lbs
You are right, and open cell spray foam and polyisocyanurate would absorb moisture when buried. This is XPS and it's not the first time I've seen it absorb much more water than the listed water absorption rate listed by the manufacturers.
@@northernbuiltpro7197 so not to be rude but what are you showing that the moisture absorption is higher than rated and can’t be a problem in homes if it’s not dealt with before it’s a problem? Or are you trying to figure out a way to prevent it?
@greggcallahan1580 My hope was to create awareness that moisture absorption can change how the insulation performs. The video is a companion to an article on my blog discussing frost protected shallow foundations in cold climates. www.northernbuilt.pro
@@northernbuiltpro7197 thank you 🙏
Yikes, any idea what caused the failure?
Closed cell spray foam shrinks slightly as it cures. This places the foam under a tension. Usually, the polyurethane foam provides a good enough bond where the connection between the surfaces is maintained. Occasionally, wood framing will twist just enough to break the bond, what you see is the result. The foam acts as both the insulation and air seal, in cold climates, this failure of air control can lead to moisture damage from air moving along the broken connection and condensing on any cold surface behind. Good question.
@@northernbuiltpro7197 Thank you for the explanation!
I'm really curious to see more of this and how it turned out. It looks really nice!
Ahh, nice but best if door comes with a handle to pull on...
Nice! For the people that wing it every step of the way until the end, when it matters, like me.
I like it
Hey guys do you do orders for UK or Hungary?
It would be interesting to see if the range in temperature on the wall (looks like 66.2 - 62.4, roughly) divided by the temp difference from outside to inside (18) is consistent, or if the temperature range gets disproportionately larger / smaller as the outside / inside delta gets larger. I suppose a complicating factor is that the temp difference for outside / inside is not super constant, so what you see on the IR camera may be influenced by the difference from several hours ago, too.
I'll do this again when the temps get really cold and use the video feature on the thermal camera so you can see the temp scale.
Oh boy should be scared for winter
I'll try to post a couple updates as temperatures continue to cool. Thanks for the comment.
