Cross Laminated Timber (CLT)

LISTEN...


Cross Laminated Timber is relatively new to the industry, but some manufacturers are going to the effort of making the panels air-tight in fabrication.

CLT roof installation in progress. Note taped seams and crane 'pick points'

Important considerations for Cross Laminated Timber application:

  • May be able to act as multiple layers - structure, vapour retarder, air barrier, and finish
  • Long lengths of panel may make for quick closing in of buildings and ease of install for windows and doors
  • Some manufacturers provide milled precision for edges and openings, adding uniformity to air barrier continuity.
  • CLT panels are very heavy. Specialized installation with a crane truck is required.
  • A plan must be made for service cavities, chases or bulkheads to be added for utilities.
