Electrical outlet protection
STI offers excellent solutions for electrical outlet boxes, the most common penetrant on a typical construction project. SpecSeal® SSP Putty Pads, intumescent, non-hardening putty pads, are tested for 1 or 2 hour ratings on a wide variety of metal and plastic boxes with metal or plastic face plates.
STI’s SpecSeal® Series EP Box Inserts are intumescent pads that insert into the back of electrical boxes. The thin, supple pads do not significantly reduce available box volume, and in the event of fire, expand up to 60x to ensure ratings of 1 or 2 hour walls are maintained.
