Engineered Wood Products

Sustainability – High Quality – Consistency

Wood products | Griff Building Supplies

Today’s building industry is limited by having to utilize younger and smaller trees for their lumber. Cutting down old growth forests for wood fibre is not an option anymore. Engineered products are increasingly becoming the norm for building materials as the market realizes its advantages, benefits and sustainability. In fact, traditional methods of sawing lumber from trees wastes the strongest part of the tree. Engineered wood methods reconstitute this fibre to produce sustainable, consistent and highly effective products. These new products use 75% of the tree, as opposed to 50% from traditional sawmill methods.

Microllam® LVL

Microllam® LVL

TJI Joist Floor System

TJI Joist Floor System

The biggest culprit in floor squeaks is inconsistent material as with dimensional joists. Even kiln dried lumber can warp, twist and shrink. Engineered I-joists take these factors away by providing products which are manufactured to be exactly the same. Add to this that one can put all plumbing, electrical and ducting through the joist without any loss in performance, and you’ll witness another of the many advantages engineered I-joists have over conventional wood.

Silent Floor TrusJoist

TimberStrand® LSL

TimberStrand TrusJoist

This innovative product technology has a wide array of product applications. TimberStrand is used as studs, stair treads, rim board and header material. The patented process utilizes fast-regenerating species such as aspen and yellow poplar.

TimberStrand® Rim Board

TimberStrand® Rim Board

When lateral forces, vertical loads and seismic forces are a concern in your project, TimberStrand rim board is the solution. 1.25” thick rim board is manufactured in all the depths applicable to TJI silent floor joists. Rim board is also the perfect solution as strong, stable stair stringers. They’re straight, consistent, have no knots and won’t split like dimensional material.

TimberStrand® Studs
