Spring Bronze The Gold Standard of Weatherstripping
Why do professionals swear by spring bronze? Because it’s:
Extremely effective at sealing gaps from 1/16″ up to 1/2″
Incredibly long-lasting (100+ years of maintenance-free performance)
DIY-friendly (Unlike other metal weatherstripping, you can install it yourself)
Beautiful (Ages gracefully to a deep copper patina)
Once you install spring bronze properly, you will never have to weatherstrip that window or door again.
