- Everyone wants their homes to bring in the beauty of the outdoors, but which products are best and which installation techniques can hurt your performance and potentially create headaches? The Lunsfords debunk the myth of windows and doors causing all drafts, teaching stack effect and demonstrating the blower door test of their own fully-enclosed home build.
Featuring a visit to the Alpen Window factory in Colorado to meet with high performance window expert Alison Ray, footage from Bill Spohn’s fascinating high performance home built entirely in a factory by EcoCraft Homes, sun tubes from 475 High Performance Building Supply, and a rough-in blower door test. You can consult with Corbett long-distance, or find a testing professional near you to pursue excellence in your own home.

Great episode! Love the technical nature of the windows, and the comparison of why you get what you pay for, and the trade offs needed.
Your channel successfully communicates the complicated topics of home performance. We in the HVAC industry appreciate all you do!
Aw thanks Andy- I bet a lot of HVAC folks are gonna hate my guts a few epiodes from now
@@HomePerformance i'll go ahead and help you fire up homeowners. Over 70% of HVAC systems are not producing the rated performance. As you know, airflow is usually the culprit. I'm glad you're talking about these issues. They won't be on a consumers mind unless they know the problems. Again, thank you for your help getting out valuable iHVAC performance information for homeowners.
@@AndyHoltOutdoorUniversity yeah i just had to tell someone that yesterday because they built a deck around the heat pump blocking off half its airflow. people can't see airflow so they tend not to care about it.
Andy what market are you in? Im in NC.
@@HomePerformance dont threaten me with a good time!
The flow of this episode with that ending music was spectacular. The building science and alpen factory were good too😊.
Thanks Will- I’m very happy to have personally edited this season of the show, the music is really important to me.
I love how your blower door numbers were so low on your first try. Caulk, foam and care!
Even if not building a energy home.. Good windows are worth it. Cuts down on heat through window. And less noise from outside.
Yes its more.. But worth it once you experience it.
I regret doing sliders. They have more spots for dirt to stay.
most of the sliders we have are very very air leaky. you have to go high end to get anything that remotely seals well. a cheap fix is to simply not install them.
Great video. Only thing I wish it had was on wall to window ratio.
We hit that in Episode 12 T!
@@HomePerformance just something thats worth mentioning when your talking about designing windows. i do realize you have to draw the line somewhere but its a critical topic and should always be in the window conversation.
Blower door test...
What do you do for the bathroom vents or other external vents on something like this. I never see it covered or mentioned.

what software did you use for energy model? It looks feature rich.
REM/Design
having spent 20 years in remodeling I can tell you Skyligthts are just the worst. HOT as the sun beats down on them. Easy to get to 160 degrees in the shaft. With expansion and contraction they are a source of humidity and condensation. they are a source of leaks and even with the best of the best at some point there is going to be a problem.
Risk reward ratio :(
Would love to know the savings annually on double pane vs triple pane
Completely depends on everything else in the system of a particular home
What do you think about PCO air purifier? Are they safe way to remove VOC?
just had a quick read up on them and i will say no. first of all they are not designed to remove VOC's at all. they make hydroxyls to kill bacteria. but because they use UV they also make ozone, which creates all sorts of other nasty stuff. you really want to avoid anything that has UV in it.
use plenty of clean ventilation, that will dilute and push voc's outside. simple cheap and effective.
Ooh, ditto on the no if they use hydroxyl radicals to disinfect. Very chemically unpredictable.
Can you refill the gas in the glass if it empties? How do you know if it has emptied? Thermal scan?
No, I don’t believe so. You’ll know because a broken seal allows moisture between the glass and you can’t see through it when it fogs up.
Did you consider any other window manufacturers or wording your windows from Europe? Did your exterior doors come from there as well?
We considered Bewiso in Austria, but we really didn’t want to be telling our US audience that if they wanted good windows they’d have to ship them from across the ocean.
It kills me how window and roofing marketing tells you youll save 40% on energy bills. But fenestration and roofing are a small percentage of a home's energy load. So these upgrades save you 40% on only a small slice of the pie, not the whole cake.
40% is a magic marketing number that screams BS
One of the interesting things I think about the windows is how many operable windows are still in homes these days, as if we use exterior air to condition our homes any more. I know you need egress windows but most people especially in the south never open their windows. In a high performance house I would never, ever open a window unless the building is on fire. So I would go with absolute minimal egress requirements for operable windows. Rest picture.
we still get people that think polluted, pollen/dust filled, damp air is "healthy". not to mention all the noise and insects it also lets in. but having said that we have a passive home here that has no opening windows (not sure if thats even legal here). you always want fire escape but also the ability to have ventilation if the ventilation system fails.
@@tweake7175 yeah here in usa we need egress windows in bedrooms. I think everything else can be picture window.
Why not replace the windows with outdoor cameras and large flat screens?
Dammit, too late
I had to laugh at "single glazing of the '60's" it's more like single glazing of the 2000's over here.
But the scenery tho
@@HomePerformance yes you can view the nice scenery through your wall to wall windows while you wear multiple layers of clothes and huddle on the sofa under a blanket.
but thats is slowly changing, new insulation laws starting this year here. thanks to your channel and others for showing whats possible.
Maybe hobbit houses are the way to go in NZ after all
