Premier Refractory Service Provider

R&I owns a patented, high fiber system: Mono-MaxTM. Mono-MaxTM is a compressed, high temperature fiber system able to withstand temperatures up to 2800℉. This is a great system for non-metal contact applications such as furnace doors and roofs and pre-heater covers. Mono-MaxTM is popular in such environments due to its durability, light weight, and ease of replacement.

If you are interested in a Mono-MaxTM door, roof, or cover, please contact R&I today.


R&I’s precast delta and annular combination has taken us from 50 heats per roof to over 400 heats per roof. We have saved money on refractory and labor and we no longer have to stock a truckload of bricks. We will never go back to bricking our roofs.
