I want to create a letter to introduce TimberSil an EPA Approved Non Toxic and Class A
Fire Retardant Lumber to Architects and Engineers, so it can be specified for LEED projects

Hi, kjgawlick!

I'm sure that you know more about that product than anyone else here. So, my suggestion to you, would be for you to post a draft of the letter here, without putting any contact information in it, so that we can then take a look at it to suggest to you ways that you might make improvements to it.

Thanks!
