These 3/8" double cell shades were purchased at lowes for roughly 250$ and are remote controlled. They are really reducing the heat flow into the house and worth every penny.
Just wanted to say thank you for this. It’s so hard to find folks who actually test things. I’m in the process of trying to reduce my energy consumption to try and eventually go Net Zero, so this helped.
@@twiincentral8780 furnace with traditional ac condenser. I am installing a heat pump soon so I will not have any more bills. Going to do a video on that as well. Lots of good ideas for vids, just not a lot of time to make them. :)
The best thing that I have found to limit heat gain from windows is solar screens. You can buy screening material that is heavier gauge up to your preference. I bought some 90% at the old house and it reduced the temperature directly inside of the window, behind the cellular shades, by 30F. I think the cellular shades help... but it mostly just slows down the transfer. That heat is already inside your house, at this point. The solar screens diminish the amount of light entering the windows at all. I installed these as our old HVAC at the old house was nearing its end of life and it helped us limp along with it for a couple more years (and even helped us live for a year with it failed and just a couple of the portable ACs; they wouldn't have stood any chance to keep us comfortable without those solar screens. It did work out that they were only on the back of the house (the most windows and southwest facing... so a huge impact).
If your referring to solar screens that are external, yes 💯 agree. Agree with your shade comment. Heats already in the house. Shades just reduce the rate of transfer. Lots of folks don't understand this. Most films and screens work better on outside.
This is such an awesome video. I have been looking for this kind of data for weeks b/c I was thinking about ordering some double cell shades. Thank you!!
@@stem_saving1644 I have ordered a set of double cell, light diffusing shades from Select Blinds and then another set (same specs) from Blindster. I'm going to compare the two companies and see which is better at temperature regulation.
I just spent 2 days scraping off my 20-year-old window tint (not fun at all). I was planning to use one of the new Ceramic window tints, but after watching this video, this might be better.
The tint on the inside is worthless. It really needs to be on the outside to really block radiant energy. All the inside one does is heat up. The key is total energy rejection not just radiant but thermal as well.
You say the data shows a three degree drop in temperature but when you were demonstrating lowering the shade, the readings seemed to drop significantly lower than 3 degrees. Can you please clarify this for me. Thank you.
Your looking at room temperature vs shade/window temperature. Not the same. Room temp is dependent on a few variables, mostly how many btus enter per unit time and area. Similar concept as lighting a match that's 300+f... doesn't mean the room will reach that temperature.
With cellular shades, is each cell completely open from one side to the other? It appears that way from photos. I don't understand how they can be insulating with the cells totally open. Maybe I've been just looking at the cheap one?
Yes. It uses the dead air in the shade as a means of insulation. There is some air movement on the sides, but way better than not having shades. There was a company that had track sealing sides, but they never returned my questions.
@@stem_saving1644 Hi, did you end up posting those? Couldn't find them in your channel. I'd be interested in comparing other types of blinds too (like 2" Venetian) , I haven't been able to find anyone that compares them! Yours was the best by far in regards to the cellular. Thanks!
@@stem_saving1644 we have been considering double panes on west looking windows for a while but could not decide if we would still need cellular shade afterwards. I guess we will try the shades first, then, jump to double panes if necessary later on. Considering shades are much cheaper as a first step.
The real key is blocking the radiant heat that comes in. The best way is low e glass, combined with cellular shades, this will really help. I'm looking for new windows for my home. I'm in the market for triple panes. The more panes the better. Let me know how your shades work out. Best of luck.
@@stem_saving1644 Hey, wanted to check out if you have upgraded to triple panes. also as a follow up, were the ones in the video Low-e already? Thanks.
