許多當地法規要求安裝天花板輻射防火閘，以保護浴室排風扇開口，防止熱和火災經由風管擴散。防火閘安裝於外殼與格柵之間，採用隔熱毯，透過熱敏熔斷裝置在緊急情況下關閉開口。我們的防火閘符合UL標準 555C，並標示可用於防火樓板/天花板結構。

Miles ★★★★★ Oct 18, 2026

Installing this was straightforward since it sits right between the housing and grille, and the metal flaps close firmly when I test them by hand. It gives me peace of mind knowing the bath fan opening is properly protected against fire spreading through the ductwork, which my inspector will appreci

Bought this to finally get our remodel signed off, and it dropped right in between the housing and the grille with no trimming needed. The metal feels solid enough that I'm not worried about it warping over a hot shower.

Our inspector flagged the missing damper during the final walkthrough, so I grabbed one of these to get the bath fan up to code. It fit cleanly between the housing and grille, and you honestly can't tell it's up there once the cover's back on.
