Weatherstripping
Weatherstripping is the seal around a door or operable window that blocks air and water.
Why it matters
Good weatherstripping reduces drafts, improves comfort, and keeps water out.
Where people get this wrong
A good seal requires proper adjustment, not only material. Weatherstripping wears out and can need replacement.
Real-world example
You stand by the front door and feel a cold line of air at your ankles. New weatherstripping and a door adjustment can fix that faster than changing the whole door.
Where this hits your build
This comes up during selections and installation. Performance depends on the product and the install. A good window installed poorly still leaks.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
