    Wood cracking in a recent structure

    Why not use glued laminated timber for columns supporting crane beams? My factory has them in a very similar situation as this case. And they have been doing their job properly since 1940! Not only are the columns of glued laminated timber construction, the support beams for the steel rails and...

    80 years of glued laminated timber

    Casein adhesive was utilized in the glued laminated timber industry by and large until the 1960s. It is a good adhesive, not waterproof of course, so can only be used for interior applications. Waterproof resorcinol and phenol resorcinol adhesives were used during World War II for marine...

    The Peshtigo Fire was on 08 October 1871 the same night as the Chicago Fire. The Peshtigo Fire destroyed 1.2 million acres and killed between 800 and 2,000 people. It destroyed much more than just the village of Peshtigo and adjacent areas. At that time Peshtigo was home to the world's largest...

    The structural glued laminated timber industry in North America is now 80 years old. The very first glued laminated timbers made in North America were in 1934 at Peshtigo, Wisconsin. Those arches are still standing and supporting the roof of the school library in Peshtigo.

    Existing Glu-Lam Beam size question

    9 inches was a standard width for structural glued laminated timber prior to circa 1970. You indicated the beam was installed in 1993. Do you possibly mean 1963 or some other pre-1970 date? 8 3/4 inch is today's standard width and it has been since circa 1970. Sided and molded dimensions vary...

    Glulam beam cost

    That's only 9,072 BF and that piece would be 15,963 pounds in Southern Pine. Of course, standard industry width is 10 3/4" not 11". We've made a single piece up to 45,000 pounds. Fun moving that thing around in the factory! Yes, get in touch with several manufacturers. Contact American Istitute...

    timber arch bow string (tied arch)

    Does not sound like this is a bowstring truss. Sounds like a glued laminated tied-segment. These were very common in agricultural and light industrial and commercial buildings in the 1940s - mid 1960s. Are there any vertical and diagonal webs that connect curved upper chord to the horizontal...

    Existing glulam stamp

    P-149 will be the identification of the manufacturer. Plant #149 as licensed by the American Institute of Timber Construction (www.aitc-glulam.org). It took a while, but I dug out some old records. P-149 was the Weyerhaeuser Company plant at Cottage Grove, Oregon. This operation was closed down...
