Terence McCann Posted June 7, 2006 Report Share Posted June 7, 2006 What year did they start and stop producing T1-11? TIA Quote Link to comment Share on other sites More sharing options...
Scottpat Posted June 7, 2006 Report Share Posted June 7, 2006 I did not know that it was not still be produced. I could have sworn that I saw it at the lumber yard last week. As for when it was first produced, I would say it was back in the mid-1960's. Quote Link to comment Share on other sites More sharing options...

hausdok Posted June 7, 2006 Report Share Posted June 7, 2006 Hi, Sure, but he titled his thread "Masonite" T1-11. Does Masonite still make it? T1-11 is a pattern designation originally used for grooved plywood graded for use as both sheathing and siding. Then manufacturers began producing engineered wood products that looked similar. Around here, I see the plywood product, L-P has a version and Weyerheauser has a version. I'm sure there are others. Can't say that I've ever seen the Masonite product around here though. Did you try contacting Masonite directly? ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
Paul MacLean Posted June 7, 2006 Report Share Posted June 7, 2006 T1-11 was first developed as a siding pattern by the Douglas Fir Plywood Association, now APA (http://www.apawood.org/index.cfm). It was very popular when I was an APA field rep back in the late '60s, and may date from the late '50s. It is still being produced today. I have it on my house and replacement panels are available. The real T1-11 is not Masonite, but Masonite probably has a similar siding panel design. If you really need to know, you can ask APA at their web site.

Jim Baird Posted June 7, 2006 Report Share Posted June 7, 2006 Terry, I have seen the Masonite panel product only once, and the one application had failed miserably. It bowed and puffed out and puuled out past nailheads and left seams open. The homeowner was still trying to get some kind of remedy from vendorand/or manufacturer at the time.

Les Posted June 7, 2006 Report Share Posted June 7, 2006 As I recall, T 1-11 was a Champion Lumber product. It was structural at 19/32nds and tongued. 11inches of face and one inch groove. I believe it was made with a propriatary process of extreme pressure and heat under license from a company in Germany. First I knew was 1961 with a major process change in 1976 that eliminated the voids in the skin. Around here any patterned plywood is commonly referred to as t 1-11 Quote Link to comment Share on other sites More sharing options...
