Pacific Northwest project planning

Detail for drainage,
drying & seasonal change.

Wide trim can be sensitive to uneven moisture exposure. Thermal modification reduces movement, while backing, flashing, fastener placement and finish help control the installed result.

Thermal modification reduces moisture uptake and seasonal movement compared with the same species untreated. Tight joints, secure fasteners and finish life still depend on acclimation, correct installation, drainage and maintenance.

Thermal modification reduces dimensional movement; compare product-specific data for the selected materials.

HEAT + STEAMHeat-and-steam process

Modified with heat and steam, without added wood-preservative chemicals or plastic resins.
