Engineered to manage moisture, airflow, sound, and load—where building assemblies fail first and performance matters most.
Structured Strand™ is a customizable, three-dimensional entangled polymer mesh engineered to preserve critical space inside building assemblies.
By maintaining open drainage paths, continuous airflow, and resilient separation layers, it prevents the collapse, compression, and blockage that lead to moisture damage, poor acoustics, and premature system failure.
For builders, Structured Strand™ delivers consistent, predictable performance across walls, roofs, floors, and foundations—without relying on organic materials that warp, rot, or degrade. Lightweight, easy to install, and engineered for specific applications, it simplifies construction while supporting long-term durability, code compliance, and system reliability.
Structured Strand™ is engineered into application-specific forms—using rigid high-density strands for rainscreen cladding, resilient strands for tile uncoupling and sound control, rigid open strands for roof ventilation and drainage, high load-bearing strands for foundation drainage, and lightweight flexible strands for masonry and stone walls—so each assembly gets the exact performance it demands.
Structured Strand™ isn’t an off-the-shelf component—it’s a core technology Keene Building Products has engineered, refined, and manufactured for decades. By controlling strand density, rigidity, thickness, and bonding methods in-house, Keene designs application-specific solutions rather than one-size-fits-all products.
When architects and contractors specify Structured Strand™ systems, they’re relying on a manufacturer that understands how assemblies behave—not just how products are sold.
Structured Strand™ technology is the foundation behind many proven projects across residential, multi-family, and commercial construction. From rainscreen wall assemblies that dry properly over decades, to quieter floor systems in multi-story buildings, to roofs and foundations that continue to ventilate and drain long after installation—these systems are performing where it counts.
Keene Building Products and Eco Gardens transformed a 5,000 sq. ft. Chicago rooftop into a sustainable urban retreat with a green roof, sports courts, and outdoor kitchens. Featuring Keene Green’s RB-20 Root Barrier, PCD-45 Drain, and Aqua Balance Mat, the system optimizes water retention and drainage for long-term performance.
Keene Building Products partnered with Habitat for Humanity of Mahoning Valley in Fall 2024 to enhance a SIP home in Salem, Ohio, using ViperVent™ CDR. This drainage and ventilation mat prevents moisture buildup, reduces rot, and extends roof lifespan. Ideal for cedar shingle/shake applications, it promotes durability and energy efficiency. By integrating ViperVent™ CDR, the project ensures long-term structural resilience while supporting sustainable building practices.
To prevent moisture damage behind stone, stucco, and fiber cement, this Austin luxury apartment complex used Keene’s Driwall™ Rainscreen 020-1. The drainage mat ensures proper ventilation and moisture control—protecting wall integrity and long-term project profitability.
To reduce floor-to-floor noise in the largest U.S. multifamily project of 2015, Quiet Qurl® 025 by Keene was installed in this 989-unit Irvine, CA complex—delivering quiet, comfortable living in a high-end, amenity-rich community.
It preserves critical air and drainage space inside assemblies, preventing moisture entrapment, restricted airflow, sound transmission, and long-term degradation.
Unlike organic or rigid components, Structured Strand™ won’t rot, warp, corrode, or permanently compress. It’s polymer-based and engineered to maintain performance over time.
Yes. Products utilizing Structured Strand™ are designed to meet or exceed applicable building code and testing requirements for their intended applications.
No. Most Structured Strand™ products are lightweight, flexible or semi-rigid, and designed for fast, contractor-friendly installation with common tools.
Yes. Structured Strand™ is engineered into solutions for walls, roofs, floors, masonry cavities, and foundations—each optimized for its specific performance demands.
