The Triton Backer Board represents the next generation of tile installation substrates, offering a lightweight, high-performance alternative to traditional cement backer boards and gypsum underlayments.
Manufactured using advanced magnesium oxide (MgO) technology, Triton delivers exceptional strength and durability while remaining easy to handle, cut, and install. Its innovative composition allows installers to score and snap panels quickly, reducing labor time and improving jobsite efficiency.
Unlike conventional backer boards that may swell, peel, or delaminate over time, Triton is engineered to maintain long-term dimensional stability in both wet and dry environments. This makes it an ideal substrate for tile installations in showers, bathrooms, kitchens, laundry rooms, and other moisture-prone areas.
Designed with contractor productivity in mind, Triton creates minimal dust during cutting and contains no crystalline silica, VOCs, or harmful chemicals. The result is a cleaner, safer installation process without sacrificing performance.
Whether used on floors, walls, or ceilings, Triton provides a reliable foundation for ceramic tile, porcelain tile, natural stone, and other surface finishes. Its combination of lightweight handling, durability, moisture resistance, and code-compliant performance makes it a trusted choice for both residential and commercial construction projects.
For installers seeking a faster, cleaner, and higher-performing backer board solution, Triton delivers professional-grade results built to last.
