HydroFlame™ Firestop Putty Pad

Install trusted fire seals around electrical boxes with putty pads from HoldRite.

HoldRite™ HydroFlame™ fire putty pads are a non-curing, single component, fire-rated material for membrane-penetration firestop sealants. They are ideal for protecting recessed electrical boxes – metallic and non-metallic. The intumescent properties cause our fire putty pads to expand when exposed to heat, creating a fire-rated seal that will stop penetrants from spreading.

Installing Firestop Putty Pads

Since our putty pads are single component, there’s no additives required or on the job mixing. Up-to-code and easy to install, it’s no wonder pros trust HoldRite putty pads on the job site. Simply peel off the backing and apply the fire putty where needed. The adhesive putty pad is moldable and will stick to all common building surfaces. The seal is instant, providing UL-Listed fire, smoke and gas protection with no curing period.
