Sometimes on power generation equipment, what is actually there doesn’t look just like the drawings.  as plants have cycled (sometimes thousands of times), ductwork and their expansion joints don’t go back just like new, and refractory and crown seals don’t either.

we understand that, and so does isomembrane®.  because we fabricate on site, we design to existing conditions, not to drawings.  this also means no manufacturing lead times.

isomembrane® is a long term solution to your expansion joint and dead air space leakage challenges. 

In 1997, High Temperature Technologies, Inc. was created with a desire to find innovative solutions to challenges that have plagued power plant operators.

Our product isomembrane® has an impressive track record successfully sealing air-in leakage control issues. 
If you have a challenge that you are interested in looking at from a new perspective, give us a call!
