Our Story
MagSheathing™ was founded by builders, for builders. Having worked in construction and seen firsthand the limitations of OSB and drywall — warping, mold, fire risk — our founders set out to bring a better product to the North American market.
After years of sourcing, testing, and refining our supply chain, we launched MagSheathing™ with a simple mission: supply the highest-quality Magnesium Oxide boards available, backed by real technical knowledge and responsive service.
Based in British Columbia, we supply builders, contractors, developers, and architects across Canada and the United States. Whether you're framing a single-family home or developing a multi-unit commercial complex, we have the product and the expertise to support your project.
Our Values
Quality First
Every batch of MagSheathing™ is quality-controlled to meet or exceed North American building standards. We don't ship product we wouldn't use ourselves.
Honest Service
We give straightforward advice on product selection, specification, and installation — even if it means recommending a competitor for a niche application we don't cover.
Sustainability
We believe the building industry has a responsibility to reduce its environmental footprint. MGO is our contribution to a greener built environment.
Reliable Supply
We maintain inventory and relationships to ensure product availability when your project needs it — without long lead times or supply surprises.
Serving Canada & the USA
MagSheathing™ ships to construction sites and distribution centers across Canada and the continental United States. Our BC base gives us excellent access to Pacific ports and competitive freight rates for Western Canada and the Western USA, with nationwide shipping available.
We work with individual homeowners, renovation contractors, production home builders, commercial developers, and everything in between. No project is too small or too large — contact us to discuss your needs.
