What is Kiln-Dried Treated Timber?
Kiln-Dried Treated Timber is wood that undergoes pressure treatment to protect against rot and insects, followed by kiln drying to remove excess moisture and reduce the wood's moisture content to stable levels.
Why choose KDT over regular Pressure-Treated (PT) timber?
KDT timber is pre-shrunk and stabilized, meaning it is much less likely to warp, twist, or shrink compared to standard wet pressure-treated wood. It is also lighter to carry, easier to cut, and can be painted or stained immediately without waiting months for it to dry.
Can KDT timber be used indoors?
Yes. KDT timber can be used for structural interior framing, wall studs, and subflooring exposed to dampness. However, exposed treated wood should be avoided in areas near food preparation or on surfaces frequently touched by bare skin.
How do you maintain and seal KDT timber?
Although it resists rot, KDT wood should still be sealed with a water-repellent sealant or semi-transparent exterior stain to protect against UV rays and weathering. Always use hot-dipped galvanized or stainless steel fasteners, and apply an end-grain preservative to any cut edges.
What safety precautions should be taken when working with KDT timber?
Always wear an appropriate dust mask and eye protection when cutting or sanding treated timber to avoid inhaling wood dust and chemical preservatives. Never burn treated timber, as it releases toxic fumes and ash; dispose of all offcuts according to local rules.
