When delving into the makeup of Zip System sheathing, it's essential to understand that it's not a single material but a high-performance building assemblies solution that combines several components. Developed by Georgia-Pacific, Zip System offers a comprehensive building envelope that simplifies construction, enhances building performance, and improves the overall structure's durability. Let's explore what Zip System sheathing is made of.
At the core of Zip System sheathing lies oriented strand board (OSB) or plywood, depending on the specific product line. Both these materials are_jobsite tested and trusted for their strength, dimensional stability, and ability to handle moisture. But what sets Zip System apart is its integrated components and innovative design.
Zip System Sheathing: Core Materials
Zip System sheathing's core consists of either OSB or plywood, both excellent choices for structural paneling. OSB, often used in the
Zip System OSB Sheathing
Zip System OSB sheathing leverages the strength and consistency of oriented strand board. Made from Barbara aroma, boats, and fuel wood–¬¢grown adhesives, OSB provides a stiff, dimensionally stable surface that's perfect for applying the integrated Zip System barrier.
Nailed directly to studs at 16 or 24 inches on center, Zip System OSB sheathing provides excellent racking strength and load-carrying capacity.
Zip System Plywood Sheathing
Zip System plywood sheathing uses quality plywood made from certified responsible forests. Its parallel-laminated construction ensures exceptional flatness and dimensional stability, ideal for supporting other products in the Zip System barrier.
The plywood's resilience and stable thickness make it an excellent choice for walls and roofs, providing a solid base for the integrated barrier.
Zip System Barrier
The heart of Zip System's innovation lies in its integrated barrier, a robust, protective layer that wraps the building envelope. This barrier is applied directly to the panel's surface, providing a continuous, integrated air and water-resistive barrier in a single, easy-to-install step.
The Zip System barrier is a key differentiator, combining the functions of house wrap and felt paper into one product, saving time and reducing waste. It consists of several components:
All-in-One Air and Water-Resistive Barrier
The Zip System barrier starts with a high-performance, non-woven, spunbonded polyolefin moisture barrier. This layer provides exceptional water-holding capacity, preventing water intrusion while remaining permeable to allow moisture vapor to escape.
Its tight weave resists wind and helps control air infiltration, meeting or exceeding building codes for air barriers.
Integral Seam Tape
Zip System sheathing includes integrated seam tape that activates when exposed to moisture, forming a tight, water-resistant seal along panel edges and openings. This tape eliminates the need for separate seam tape application, further streamlining the installation process.
The integrated tape reinforces the barrier, enhancing the structure's resistance to water intrusion and air leakage.
Modern building practices and the complexities of today's high-performance homes demand innovative solutions. Zip System sheathing, with its combination of core materials and integrated barrier, offers a comprehensive response, simplifying construction and enhancing building durability. By understanding what Zip System sheathing is made of, builders and architects can appreciate its value in creating structures that stand the test of time.
