Firestop Putty FSP™ - Nelson Firestop


Firestop Putty FSP™, Nelson Firestop

Nelson Firestop Putty is a completely pre-mixed and ready to use formula that can be hand pressed into place forming an immediate fire seal. When exposed to fire the intumescent material expands to seal voids created from fire exposure on deteriorating penetrating items.  Firestop Putty is a blend of organic and inorganic materials that is hand moldable.

Firestop putty is ideal for metallic and non-metallic pipes, insulated pipes, cables and ductwork in a variety of fire rated floor or wall construction.  It is especially suitable for applications where re-penetrating the opening is needed after initial installation since the material remains pliable and does not set up.

Features:

  • Quick and Easy Installation - no special tools required.

  • Does not require cable derating.

  • No mix, no waste, no mess.

  • No curing or drying time. Provides an immediate firestop.

  • Reusable for convenient retrofit.

  • Non-toxic.

  • No Shelf Life.

  • Smoke and Gas Tight.

  • Weather Resistant.

  • Intumescent.

  • Easily Repenetrated
