It's salt. Water soluable. Sales reps do a lot of side stepping and double talking, but there is now way around the fact that salt applied to wood exposed to the exterior will eventually leach out. I dug into this in considerable detail some years ago and found independent research studies verifying that salt-based preservative treated lumber exposed to weather never lasts long, despite manufacturers claims to the contrary. If meant for use in a protected application (sill plates, for example), then this is an excellent choice. what is the importantance of indicating the species? I don't see that as relevant.

TimberSil claims to be a silicate-infused wood product (with some unfortunately florid marketing language about "glass wood fusion"). The MSDS does not indicate any salt, and the leachate data on the MSDS does not support Anon's claims. The website information states that normal exterior exposure fasteners and hardware may be used, which would not be true if TimberSil utilized salt in its process. So I am curious where the salt claim originates. I cannot find enough information about what TimberSil is from the website in order to be able to specify it with confidence. The manufacturer would be wise to obtain an ICC-ESR and also to publish performance data based upon newer ASTM standards editions. Plus invest in some downloadable guide specs and tech data sheets. And maybe lose the "glass wood" stuff - at least when talking to specifiers.

In the absence of the product being addressed by AWPA an evaluation report is only a professional opinion regarding code compliance. How much you can rely upon this professional opinion depends on the knowledge of the individual who prepared the opinion. anon (Unregistered Guest) Unregistered guest Posted on Wednesday, January 04, 2012 - 05:53 pm:    And I stand corrected, thanks Phil. My comments were in reference to what I thought Timbersil was - a borate preservative treatment. It is not. I found this to be an excellent source of information on this product, and learned something today! http://www.finehomebuilding.com/item/9172/timbersil-decking Catherine Bradshaw (Unregistered Guest) Unregistered guest Posted on Thursday, June 06, 2013 - 07:53 pm:    Can anyone tell me if Timbersil would be appropriate for vegetable garden beds, or if the pressure treatment poses any danger of chemical leaching. Thanks. Rafaelo (Unregistered Guest) Unregistered guest Posted on Thursday, October 24, 2013 - 01:50 pm:    Sadly, it appears Timbersil does not live up to its hype. The following article discusses problems with decking, and with garden beds. The problem is not leaching. The problem is warping and rotting. Apparently a University of Oregon study concluded Timbersil is only slightly more rot resistant than untreated pine, which is to say--it rots. http://www.gazettenet.com/news/7882121-95/special-report-summit-house-projects-woes-linked-to-wood-choice CHalunen (Unregistered Guest) Unregistered guest Posted on Friday, January 17, 2014 - 01:08 pm:    The class action law firm Halunen & Associates is investigating defective TimberSIL glass-infused wood products. These products are vulnerable to warping, rotting, and paint adhesion failure.
