Featured Products

A safer, stronger, healthier way to build.

NEXGEN MAXTERRA® MgO is a best-in-class, innovative, and versatile mineral-based building material primarily composed of magnesium oxide and sulfate. It stands as a superior alternative to conventional materials such as OSB, plywood, gypsum, and gypcrete by offering unmatched non-combustibility, fire resistance, water resistance, as well as mold and mildew resistance, all without the use of harmful chemicals.

Distinctly mineral-based, it’s free from VOCs and quartz silica. Its sulfate-based formulation distinguishes it from traditional chloride-based MgO products, addressing corrosion issues and aligning with future safety and environmental compliance standards.

Every product from NEXGEN is third-party certified by the International Code Council Evaluation Service (ICC-ES), ensuring compliance with rigorous building code standards so that you can build with confidence.

Rmax ECOMAXci® Ply

Continuous Insulation for Cladding Attachments in Commercial Exterior Walls

Rmax ECOMAXci® Ply is a composite product of polyiso insulation with inorganic, polymer coated glass fiber mat facers bonded to 5/8” or 3/4” fire retardant treated plywood (FRTP). This insulation has been tested for multiple NFPA 285 assemblies and is approved for use in exterior walls of buildings of any height.

R-Guard Cat 5

Air and Waterproof Barrier

Cat 5 is a primary air barrier designed for use over above-grade structural surfaces prepared with Joint & Seam Filler and FastFlash. Cat 5 produces a highly durable, seamless, elastomeric weatherproofing membrane on exterior sheathing, CMU backup walls, and precast concrete. Proven to prevent water and air penetration of the building envelope in conditions ranging from everyday to the 155-mph winds of a Category 5 hurricane.

ACM Series System

Aluminum Composite  Panel Systems

ACM Series panels allow for larger surface area coverage than aluminum panels and can be lightweight. ACM panels offer excellent weather resistance and a very long lifespan.

Kingspan Light + Air

Skylights, Canopies and Translucent Wall Systems

Whether you’re designing a manufacturing facility or an office complex, daylighting should play an important role in the building’s overall design and function – and should also be cost-effective for the building owner. While there are numerous ways to deliver sunlight into interior spaces, perhaps the easiest and most bottom-line friendly method is through light-transmitting wall systems.
