This change was done in an apartment in Chicago Illinois
The room often felt stuffy even when the weather was cool
Before the update opening windows did not help much
Air movement was weak
During the work fitting the new window took longer than expected
The frame needed small adjustments
After the upgrade airflow improved and the room felt fresher
Sleeping became more comfortable
The change was small but it made a noticeable difference
One window still needs further sealing
If you live in Chicago and deal with poor airflow windows are worth checking
Real note
Comfort often comes from
small fixes
