About This Product


SpecSeal SSP Putty is a non-hardening, intumescent compound designed to seal through-penetrations as well as certain membrane penetrations (med-gas valve box, tub & shower valve, clean-out tee) against the spread of fire, smoke and hot gasses. SpecSeal Putty expands up to eight times its original size when exposed to high temperatures or flames.

Requiring no tools, SpecSeal SSP Putty is soft and pliable making it easy to install by hand packing into openings. Its aggressive adhesion makes it suitable for use with all common construction materials as well as cable jacketing and pipes. SpecSeal Putty remains soft and easy to reuse or retrofit.

SpecSeal SSP Putty Pads provide this same level of protection in a release lined pad for easy application to electrical boxes or other penetrants. The pad is conveniently sized to fit a typical 1-1/2 in (38 mm) deep 4S box with no cutting or piecing required. Faced on both sides with a convenient poly liner, SpecSeal Putty Pads are easily applied with no mess or excessive residue.

SpecSeal SSP Putty and Putty Pads are used to seal through-penetrations as well as construction gaps and blank openings. SpecSeal Putty Pads are used to seal around electrical boxes to reduce sound transmission (see Technical Update) and increase fire resistance. These pads also provide a metered method of application when sealing through-penetrations and in some applications, are used to provide a cushion to allow movement due to settling, expansion and contraction, or vibration.


The firestopping putty shall be a one-part, two-stage intumescent, non-hardening compound. The putty, when exposed to high heat or flame shall be capable of expanding a minimum of five times. Range of continuing expansion shall be from 230°F to less than 1,000°F (110°C to less than 538°C). The putty shall be soft and pliable with aggressive adhesion and shall not contain any water-soluble intumescent ingredients. The putty shall be UL Certified and/or FM Systems Approved and tested to the requirements of ASTM E814 (UL1479), CAN/ULC-S115 and UL263 (ASTM E119, NFPA 251).
