Everkem: High-Performance Sealants and Adhesives

Everkem is a leader in technical chemistry, offering a comprehensive range of firestop sealants designed for a variety of construction environments. Their products, such as the Flame Tech and Firestop 814+ lines, are engineered for superior adhesion and durability.

  • Versatile Applications: From HVAC ductwork and plumbing penetrations to electrical conduits, Everkem sealants provide a flexible, smoke-tight bond.

  • Intumescent Technology: Many Everkem products feature intumescent properties, expanding when exposed to heat to fill gaps left by melting pipes or cables.

  • Compliance Ready: These formulations are rigorously tested and UL Classified, meeting the stringent requirements of modern building codes.

Unique Firestop Products: Innovative Systems for Complex Penetrations

When standard caulking isn’t enough, Unique Firestop offers specialized hardware and sleeve systems that simplify the protection of cable runs and metallic pipes. Known for their “split-sleeve” designs, Unique Firestop products are the preferred choice for retrofitting existing structures where cables are already in place.

  • Easy Retrofitting: Their systems allow for the organized passage of communication and power cables without the mess of traditional putty or pillows.

  • Reusable Solutions: Unlike permanent sealants, many Unique Firestop systems allow for easy additions or changes to wiring, making them ideal for data centers and healthcare facilities.

We provide different types of fire protection items, including:

  • Special sleeves that block fire
  • Sealants that expand when heated
  • Protective collars for pipes
  • Fire-resistant putty pads

All our products do more than just meet safety rules—they go above and beyond to keep buildings and people safe.

We understand what building owners need and offer products that are both effective and eco-friendly.
