At Specified Technologies Inc. (STI) we focus solely on the firestopping business. With over 25 years of firestopping experience, the founders of STI are committed to the development of innovative, reliable firestopping solutions. This is no small task considering the complexity of today's building construction and the increasing use of combustible penetrants. Marketed under the SpecSeal® and EZ Path™ brands , the STI product line is simple in design yet powerful in performance. The result is a low cost, outstanding fire protection system that is easy to install.

All our systems are third-party tested to the highest industry standards and provide the best "F" & "T" ratings in the business. They are also an excellent smoke seal because of their remarkable speed of expansion. Since the intumescent materials in SpecSeal® products are highly water-resistant you can count on maximum long-term performance.

The development of a line of products that would allow safe and effective sealing of nearly any through penetration could be considered nothing less than a work of art. We have mastered the art of firestopping.

At STI we are pushing the "Art of Firestopping" to a new level.
