WOOD MEETS CODE
Advanced technology and modern building codes are expanding the opportunities for wood in construction.
WOOD COSTS LESS

Wood products offer advantages in terms of material, construction and environmental costs.

WOOD IS RENEWABLE

Wood is a renewable and responsible choice that helps reduce our environmental footprint.

Glulam

Guardian is the only manufacturer of Glulam in Ontario as we typically manufacture it for bridge and now building applications.

  • Straight Beams
  • Curved Beams
  • Double Tee and Triple Tee
  • Slabs 
  • Slabs for concrete...see Bubble Lam

Glulam (laminated beams) is the natural alternative to steel or concrete. Glulam is a natural structural material that is economical, strong, and attractive looking.

Glulam is made by gluing together, under pressure laminates of timber that have been accurately planed. The resulting product is strong, stable, and corrosion proof with significant advantages over structural steel and concrete.


Glulam is made with wood from sustainable forests. Canadian forests are some of the best managed in the world, where reforestation and environmental considerations are given high priority. The trees used are usually  Douglas Fir, Black Spruce or others.

 


The manufacture, distribution, and treatment of Glulam, all consume less energy than any other building materials. Glulam is a long-lasting material that’s easy to work with.

 

 

Curved and Twisted Beams are available .

Glulam (glued-laminated timber) is a structural timber product manufactured by gluing together individual pieces of dimension lumber under controlled conditions. The attributes of this wood product account for its frequent use as an attractive architectural and structural building material.

In the manufacture of glulam, the wood pieces are end jointed and arranged in horizontal layers or laminations.

Laminating is an effective way of using high strength lumber of limited dimension to manufacture large structural members in many shapes and sizes. Glulam is used for columns and for beams and frequently for curved members loaded in combined bending and compression.

The lumber used for the manufacture of glulam is a special grade (lamstock) which is purchased directly from lumber mills. It is dried to a maximum moisture content of 15 percent and it is planed to a closer tolerance than that required for dimension lumber.

Canadian glulam is manufactured in three species combinations: Douglas Fir-Larch, Hem-Fir and Spruce-Pine as shown in Table 3.6.

 Table 3.6: Commercial Species for Canadian Glulam
Commercial Species Group Designation Species in Combination Wood Characteristics
Douglas Fir-Larch
(D.Fir-L)
Douglas fir, western larch Woods similar in strength and weight. High degree of hardness and good resistance to decay. Good nail holding, gluing and painting qualities. Colour ranges from reddish-brown to yellowish-white.
Hem-Fir Western hemlock, amabilis fir, Douglas fir Lightwoods that work easily, take paint well and hold nails well. Good gluing characteristics. Colour range is yellow-brown to white.
Spruce-Pine Spruce (all species except coast sitka spruce), lodgepole pine, jack pine Woods of similar characteristics, they work easily, take paint easily and hold nails well. Generally white to pale yellow in colour.

 

All Canadian glulam is manufactured using waterproof adhesives for end jointing and for face bonding and is therefore suitable for both exterior and interior applications. However, the specified strengths used in design will depend upon whether the service condition is wet or dry
