Pressure-Treated Lumber

Definition

Pressure-treated lumber is lumber that has been impregnated with chemicals under pressure to retard decay or fire.

Purpose

Pressure-treated lumber is used to increase the durability and longevity of wood products by protecting them from decay, insect damage, and, in some cases, fire. It is suitable for outdoor and high-moisture applications.

Examples of Use

• Outdoor Decks: Providing durable and weather-resistant decking.
• Fence Posts: Ensuring longevity and resistance to rot and insect damage.
• Playground Equipment: Using treated wood for safety and durability.

Related Terms

• Preservative Treated: Wood treated with chemicals to resist decay and insects.
• Fire-Retardant Treated Wood: Wood treated to resist ignition and slow the spread of fire.
• Weather-Resistant Wood: Wood treated or naturally resistant to weathering.

Notes

• Handling: Protective measures should be taken when cutting or handling pressure-treated lumber to avoid exposure to chemicals.
• Environmental Impact: Treated lumber should be disposed of properly to prevent environmental contamination.
