SpecSeal® SSP Putty & Putty Pads – High-Performance Fire, Smoke & Sound Sealing

SpecSeal® SSP Putty is a non-hardening, intumescent compound designed for sealing through-penetrations and certain membrane penetrations against the spread of fire, smoke, and hot gases. Expanding up to eight times its original volume when exposed to high heat, it is soft, pliable, and easy to install by hand. SpecSeal® SSP Putty Pads deliver the same performance in a convenient release-lined pad, perfect for protecting electrical boxes and reducing sound transmission.


Key Features & Benefits

  • Non-hardening formula allows easy retrofitting and reuse
  • Endothermic fillers absorb heat and release water for added protection
  • Aggressive adhesion to most construction materials, cables, and pipes
  • Soft and pliable for tool-free installation
  • No water-soluble expansion ingredients – enhanced water resistance
  • Excellent sound attenuation properties (STC 62)
  • UL Certified and FM Systems Approved for up to 2 hours of protection
  • Zero VOC formula (complies with SCAQMD Rule 1168)

Applications

  • Sealing through-penetrations in walls and floors
  • Membrane penetrations such as med-gas valve boxes, shower valves, and clean-out tees
  • Fire and smoke protection around electrical boxes
  • Soundproofing to reduce noise transmission through electrical and communications boxes
  • Cushioning against movement from settling, vibration, or thermal expansion
