Construction and Materials
Biewer Lumber specializes in high-quality treated lumber products designed for durability and extended lifespan. Their treated lumber is manufactured using advanced pressure-treating processes that force preservatives deep into the wood fibers, offering superior protection against decay, fungal growth, and insect infestation.
The core material for Biewer Lumber's treated lumber products is typically kiln-dried lumber, which is a crucial step in preparing the wood for the pressure-treating process. Kiln-drying reduces the moisture content of the lumber, allowing for deeper and more uniform penetration of preservatives. This also helps to minimize warping and checking after treatment.
The specific preservatives used by Biewer Lumber are designed to be effective and environmentally responsible. While the exact chemical formulations can vary based on industry standards and specific product lines, common treatments for wood preservation include:
- Alkaline Copper Quaternary (ACQ): A widely used copper-based preservative that provides excellent protection against fungal decay and termites.
- Copper Azole (CA): Another copper-based preservative known for its effectiveness and environmental profile.
The construction process involves:
- Selection of Quality Lumber: Biewer Lumber sources high-grade lumber to ensure structural integrity and optimal treatment penetration.
- Kiln-Drying: Lumber is dried in kilns to a specified moisture content.
- Pressure Treatment: The dried lumber is placed in sealed cylinders, and a vacuum is drawn. Then, the preservative solution is introduced under pressure, forcing it deep into the wood cells.
- Drying/Fixation: After treatment, the wood is often dried again to allow the preservatives to fix within the wood structure.
This combination of carefully selected materials and rigorous construction methods ensures that Biewer Lumber's treated lumber products are suitable for a wide range of applications, including decks, fences, patios, and other outdoor structures where exposure to the elements is a concern.
