Why a house can feel drafty with the windows shut
Leaks and air falling off cold surfaces feel like a draft with the sashes shut.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A house can feel drafty with the windows shut because outdoor air still enters through gaps, or because indoor air cools and falls along cold surfaces. Skin reads moving air and a cold nearby surface as a draft, and that feeling does not require an open sash. The opening covers cold glass making air fall, leaks driven by wind and stack, and a register that feels like a draft.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
