New dowel laminated timber product to be used for structural applications
http://journalofcommerce.com/ Mar 27, 2017
StructureCraft Builders Corporation is building a 50,000-square-foot, all-wood facility in Abbotsford, B.C. to manufacture dowel laminated timber (DLT). DLT is made entirely from softwood and hardwood with no metal, glue or plastic….Today there are about 20 DLT manufacturers in Europe, most of them in Germany, Austria and Switzerland. DLT may be the most recent mass timber product, but it joins many others already on the market. Some of them are nail laminated timber (NLT), cross laminated timber (CLT), glue laminated timber (GLT), laminated veneer lumber and laminated strand lumber.

It’s about Amos Wood of Blockhouse who got a contract to replace six windows for the historical St. Mary’s Basilica in Halifax.
The windows will be constructed out of Sapele Mahogany, a hardwood from sub-tropical Africa. “Unfortunately,” says Amos of the material. “But it was less expensive than our Western Red Cedar, which would have been a good material to use, but cost ruled the day.” While the original windows were made of pine, Amos maintains that the pine available on the market today is “so young. “It simply doesn’t have the resistance factor that the slower growing, older wood from time ago had.” According to Amos, the forests are now working on a 60- to 80-year rotation, “which cannot give us 200-year-old wood.”
and this comment followed:
A poorer grade pine will grow up on the southwestern clearcuts, and will not be prized for the purposes this article addresses. Mills had best enjoy their “clear pine” while they still can. We know what the open grown pine looks like, full of knots and larger growth rings; generally poorer grade, and often hit by weevil, which ultimately reduces board footage. There will be far less quality pine grown from this point onward unless on private land by wise and more caring landowners. Current Crown land practices won’t grow quality pine unless by accident.
