Refractory Guidance – Informational Links
F.S. Sperry is a refractory contractor. Back in 2013, we began sharing our thoughts and experiences via our blog and email newsletter. We decided that it was time to catch up with many other industries who share information digitally.
We also found that it was helpful to create articles that answer many of the questions we heard on a regular basis regarding materials, installation methods, equipment, cost, etc. This article is a summary of key links to refractory guidance that you might find useful (so you don’t have to sift through the individual blog posts). We’ve grouped these by category.
Feel free to bookmark this page for easy future access. We’ll continue adding links to new articles as we create them. Since many of our jobs are confidential, we can’t provide photos or descriptions, but we are able to talk about our capabilities one-on-one, so reach out to us if you have questions that you don’t see answered here.
