Spacers between the glass. The good, the bad, and the ugly.

The material and structure of what's used between each pane of glass in a window or door will determine part of how energy efficient the glass is around the edges as well as prolonging seal failure.

You mentioned the drilled hole in the four piece aluminum spacer being a problem specific to that type of spacer. Doesn't the stainless steel one piece have the same problem? Or did companies find a way to teleport argon/krypton gas through glass/steel into a sealed unit..?

[@gregcorwin8316]

Prier to being sealed, the stainless IG unit enters a closed chamber where air is evacuated, argon is injected, and the IG unit is closed and sealed. The level of argon is controlled and no holes are punched into the spacer.

Thermoses are made from stainless steel because of durability and ease of cleaning, not because stainless steel is a thermal insulator. You should come up with a better sales gimmick.

[@Jaker788]

To be fair, many stainless steel alloys thermal conductivity is very low in comparison to aluminum. Only silicone and foam are lower than stainless steel.
Also the strength of stainless steel allows it to be thinner, less cross section means less thermal transfer.

[@VictorDelPrete]

Wait. “Thermally Efficient” means highly temperature conductive right? You said that was bad for aluminum, but good for stainless.

What about the duralite spacers???

[@nathanielb659]

Garbage

[@mikedreyer6737]

You usually have good stuff but this is totally mis leading the spacer that you are showing that is bowing isn't super spacer its the old swiggle seal .

[@gregcorwin8316]

swiggle was/is total crap. At 3:40 is heat mirror system
