I live in Chicago , I look for very eficient windows for winter and summer.

My climate Ontario Canada..... ideally we would do regular 180 on N,E,S walls and 272 on West.... I try never to do 366 because it has so much of a tint to it, the way i explain that to people is have you ever seen the blue windows on a car dealer, thats 366.... but canada... we only cool our house for 1 month out of the year and heat for 8+, so Argon is our friend and 1 coating of LowE so we don't fade our floors is ideal.

@x2x_maggie-xoxo853 2 years ago

Jeff, can you answer this for me? I'm in south Florida and we are doing a new construction. The North side plan has big sliding glass doors. The North doesn't ever get direct sunlight. Would it be okay to do NO low-e coatings? I want the most amount of light coming into the house. Or is it still advisable to do low-e? Is there anything less than 270? Thank you!!!!

Jeff do you have a video about a low e hard coat that is on the room side that keeps heat from escaping like Andersen heatlock coating? I can’t find a video on it that shows how the different tint and reflectiveness looks and pros and cons

Is argon healthy to breathe?

Higher levels can cause nausea, vomiting, unconsciousness, coma and death. No occupational exposure limits have been established for Argon. However, it may pose a health risk.

@houstonwindowexperts - Jeff what is your selection criteria for recommending other window companies that are outside your area? What vetting process is done and how is it updated to make sure the recommended window company is still on your list?

@k303b4 2 years ago

I had a window company make a distinction about HOW MUCH argon gas a window contained, saying that companies will tell you their windows contain it but it's only at, say, 60% as opposed to theirs, which is at 90%. Can you please speak to this? Is this a factor to consider?

@stevekettel188 2 years ago

Hi Geoff, really interesting video. I wish you’d put the “just argon” window in front of the bulb though! I really want to stop heat entering through our large picture window, but want zero colour change / tint, and would have been interested to see how much heat transfer the argon window prevents without low e?

Is there any way to detect if my windows are with argon gas ?

Is it just sun/UV/IR? Does it also help with heat transfer in general; i.e. summer heat outside or winter cold outside. Will triple vs single low-e help keep a hot day outside cool inside and v.v. for cold outside. Most window people online talk mostly about sun from south/west. Unclear if this based on their location. I'm in central Alabama where it gets most hot and cold for a short while and we a few big windows in direct sun S/W. Those would likely be aided. But should I get all windows done with triple to help when it gets to 10F or 100 degrees outside my N/E facing windows to keep the heat transfer to a minimum? Is it only direct light based and keeping it out? Thanks in advance for any info! Cheers!
