Paineituista

Paineituista is a Finnish term that translates to "pressure treated" in English. It refers to wood that has been chemically treated to resist rot, decay, and insect infestation. This process is commonly applied to lumber used in outdoor applications where it is exposed to moisture and the elements.

The treatment process typically involves impregnating the wood with a preservative solution under pressure. This forces the chemicals deep into the wood fibers, providing long-lasting protection. Common preservatives include alkaline copper quaternary (ACQ), copper azole (CA), and micronized copper quaternary (MCQ). These treatments are designed to be effective while minimizing environmental impact and health risks.

Pressure-treated wood is widely used for various construction projects such as decks, fences, docks, playground equipment, and structural elements in outdoor buildings. Its enhanced durability makes it a cost-effective choice for applications requiring resistance to biological degradation. It is important to handle pressure-treated wood according to safety guidelines, which often include wearing gloves and a mask when cutting or sanding the material. Dispose of treated wood properly, as it should not be burned in open fires.
