Material Overview

Perfected in our lab. Tried and tested in the harsh Canadian climate. TechBoard is a superior magnesium cement sheathing and backer board based on ZS2’s proprietary material science. TechBoard is both climate resilient and environmentally responsible without compromising on performance.


TechBoard is a proprietary magnesium-cement board formulated at ZS2 Technologies by our in-house R&D team, led by Dr. Doug Brown. They’ve developed a healthier, safer and stronger cement sheathing board that also has a greatly reduced carbon footprint compared to other cement and gypsum boards.

Testing & Certifications

We don’t just meet industry standards; we set them. By heavily investing in testing and certifications, ZS2 can confidently and safely bring innovative constructions to market that seamlessly integrate into existing regulations and industry standards.
We’ve built rigorous Quality Assurance (QA) and Quality Control (QC) procedures into our manufacturing processes to ensure streamlined delivery from production to construction. This ensures that our building materials undergo rigorous assessments to guarantee enhanced durability, resilience, and long-term performance in diverse environmental conditions. This proactive approach minimizes the risk of failures, enhances safety, and protects the investments made in construction projects.
Our team proudly collaborates with QAI Laboratories (QAI) for testing, certification, and Code Evaluation Reports for ZS2 building products. From inspecting our manufacturing equipment to batch testing our TechBoard before panel assembly, QAI acts as an independent third-party testing, inspection and certification organization to ensure transparency at every step of the process.
QAI’s certification mark is recognized with building officials throughout North America including the CCMC, the Florida Building Commission, Miami-Dade County, Los Angeles City Building Department, California State Fire Marshal, and others.
This ensures all ZS2 products that arrive on site meet and exceed project requirements.

TechBoard FAQ

Building with TechBoard has increased benefits to the overall longevity of buildings. TechBoard can be used to replace traditional sheathing products like plywood, OSB, or drywall with a fire, mold, and water-resistant solution. Additionally, TechBoard has increased structural capacities compared to traditional materials.

TechBoard is our proprietary magnesium-based cement board. Our R&D team, led by Dr. Doug Brown (Ph.D. Chemistry), has developed a proprietary high strength cement formulation which is highly fire, water, mold, and pest resistant with a significantly reduced carbon footprint vs. other traditional cement products.

ZS2 Technologies utilizes a proprietary magnesium cement formulation to create TechBoard. Magnesium oxide (MgO) is one of the most stable and highly resistant minerals to heat, which is why it’s used to make molds for molten metals, and even heat shields on spacecraft. TechBoard is highly flame resistant, produces no toxic off gasses and prevents significant heat transfer. The reason? Nearly 50% of TechBoard is chemically encapsulated water. Nearly double the amount of drywall, which is traditionally used to build 1 and 2 hour fire walls.
