Welcome to Leaf EWP Ontario's First Glulam & CLT Facility

Glued-laminated timber is a quality product with superior strength that incorporates recent improvements in timber quality and processing. Its demonstrated versatility opens the door to a world of new construction designs. 

Uses - beams and headers, columns and posts, decking, floor and roof joists, decking, arches 

Species - Spruce-Pine-Fir (Douglas fir & SYP available for custom orders)

Cross laminated timber (CLT) is a large-scale, prefabricated, solid engineered wood panel. Lightweight yet very strong, with superior acoustic, fire, seismic, and thermal performance, CLT is also fast and easy to install, generating almost no waste onsite.

Sustainable CLT offers design flexibility and low environmental impacts. CLT provides new design possibilities. 

LEAF has developed a unique product concept, designed specifically for use in floor and ceiling joist applications, that will build on the key attributes of LEAF's MultiLam.

Changes prescribed in 2012 International Residential Code Section R501.3 have been adopted by many states. When the need to offer the required fire resistance rating is factored in MultiLam offers builders a significant cost advantage.

• Stress Grades 20F-E & 24F-E
  Used for members stressed principally in bending (beams) or in combined bending and axial load. Specify EX when members are subject to positive and negative moments or when members are subject to combined bending and axial load such as arches and truss top chords. 
• Compression Grades 16C-E 12C-E
  Used for members stressed principally in axial compression, such as columns. 
• Tension Grades 18T-E 14T-E
  Used for members stressed principally in axial tension, such as bottom chords of trusses.

• Appearance Grades
  Industrial is used where appearance is not of primary importance.
  Architectural appearance have a smooth, attractive finish intended to be exposed to view in the finished structure.
