Cross-Laminated Timber (CLT) with Flexible Insulation

A cross-laminated timber panel (aka 'Crosslam' or 'Xlam') is a ‘monolithic’ form of construction that uses timber to form load-bearing solid timber wall, floor and roof panels. Openings for doors and windows are incorporated within the panels. In many cases only insulation and cladding is added to the external face.

This example shows the use of insulation installed between timber joists attached to the outside of the timber panel and faced with sheathing board.

For an example of how rigid insulation is installed with this system, see also 'CLT with Rigid Insulation '

Cladding, insulation and finishes are added and completed by other contractors.

To learn more about the CLT as a building system see also 'Choosing a Building System'
