Griffolyn® VaporGuard® is a remarkable 3-ply laminate designed to provide robust protection in a lightweight package. Its unique composition consists of an aluminum core sandwiched between two layers of multi-axially oriented HDPE/LLDPE, offering exceptional strength and durability.
What is a 3-Ply Laminate?
This refers to the construction of the material. "3-ply" means there are three layers stacked on top of each other. In the case of Griffolyn® VaporGuard®, these layers consist of:
- An aluminum core: This is a layer of aluminum, which is a strong and lightweight metal.
- Two layers of multi-axially oriented HDPE/LLDPE: These are types of plastic that are arranged in a specific way to make them strong and durable.
So, when we say Griffolyn® VaporGuard® is a "3-ply laminate designed to provide robust protection in a lightweight package," we're saying it's made of three layers (aluminum and two types of plastic) that are put together in a way that makes them strong and durable, while still being lightweight. This makes it effective at protecting whatever it's used to cover, while also being easy to handle and work with.
What Makes VaporGuard Unique and Effective?
-
Low Permeance: VaporGuard's combination of HDPE/LLDPE and aluminum delivers extremely low permeance, making it ideal for specialized applications such as radon protection, cold storage facilities, museums, and computer rooms.
- What is "Permeance"? Permeance refers to how easily something allows gases or liquids to pass through it. In the case of Griffolyn® VaporGuard®, it has "extremely low permeance," which means it doesn't let much moisture or air pass through it. This is important because it helps prevent things like water vapor or gases (like radon) from getting through the material and causing damage to whatever it's protecting.
-
ASTM Compliance: It meets Class B, ASTM E-1745-11 Standard Specification for Water Vapor Retarders Used in Contact With Soil or Granular Fill Under Concrete Slabs, ensuring reliability and performance in demanding environments.
- What is ASTM Compliance? ASTM is an organization that sets standards for many different materials and products to ensure they meet certain quality and safety criteria. When something is "ASTM compliant," it means it has been tested and meets the standards set by ASTM for its specific use. In the case of Griffolyn® VaporGuard®, it meets the ASTM E-1745-11 standard, which is a specific standard for water vapor retarders used in certain construction applications.
