The house building quality like windows was a big surprise for me too when moving to the US.
Currently more and more houses do triple glassing by default in Switzerland. Double glassing is already done since the 80’s and mandatory for all new house since a long time.
Obviously its more expensive so energy saving standards and energy prices have a lot of impact on how houses are built or renovated. Especially in Texas energy is cheap and I can see that there are not a lot of incentives to invest in lower energy usage by building more expensive.
