“In 1995, the steam system in Indianapolis pioneered the use of Fibrelite rings and covers over steam vaults. Since then, Fibrelite products have continued to be used with good success in sidewalks and street crosswalks to eliminate the burn hazard associated with metal rings and covers.”

Cleveland Thermal, LLC

“Cleveland Thermal has found Fibrelite steam manhole covers and frames to be an excellent alternative to the standard, cast iron covers. In an urban environment with high pedestrian traffic, Fibrelite steam manhole products offer the greatest reduction in external surface temperature of the cover and have much more aesthetic appeal compared to the cast iron covers that corrode and become unsightly. In addition to the Fibrelite steam manhole cover’s surface temperature reduction, they are much lighter, reducing both liability and personal injury to workers during handling. I would consider this a fabulous product with exceptional customer service.”

Duluth Steam Cooperative Association

“The Duluth Steam Cooperative Association as an agent for the City of Duluth began installing Fibrelite covers in 2002 and they are now the only manhole (steam vault) cover we use. There are currently 46 covers in the system. They were purchased because of their weight – they reduce the risk of back injuries compared to steel covers and also their insulating abilities. If a steam leak occurs in a vault a person can stand on the cover and not be affected by the heat in the vaults. The covers are installed in street situations and when a proper concrete apron is used we have had no problems with snow plows, buses or trucks popping the covers out.”

UVM Physical Plant Department

“We liked that the covers were light, easy to remove, and were rated for the H20 loading. Our scepticism was around how well the covers in the roadways would hold up to Vermont winter snow plowing, and how well they would seal out surface water. To date we have had NO issues with any aspect of these covers. Since our first 6 covers installed, we have installed 8 others. We are working with Fibrelite to develop plans to retrofit our older vaults in the near future. The Fibrelite covers met an important need on our campus to find a light; durable; temperature, corrosion and abrasion resistant cover that seals out the surface water.”
