MgO board is very strong, with properties that often exceed or match traditional building materials like OSB and even concrete. Its strength comes from its unique mineral composition and the reinforcement provided by fiberglass mesh.

Here’s a breakdown of its strength properties:

Compressive Strength

MgO board has excellent compressive strength, which is its ability to withstand forces that push down on it. This makes it a great material for load-bearing walls and flooring applications. ...

MgO SIPs and OSB SIPs are two types of Structural Insulated Panels (SIPs), which are a high-performance building material. The key difference between them lies in the material used for the exterior and interior sheathing, or “skins,” of the panel.

SIPs in general are a composite building material consisting of a rigid insulating foam core (typically Expanded Polystyrene (EPS) or Polyurethane (PUR)) sandwiched between two structural facings. This creates a lightweight, strong, and highly insulated panel ...

Yes, you can use fiber cement board as an underlayment for a deck, but its suitability depends on the specific application and it’s not a solution for every situation. Here’s a breakdown of the key factors to consider:

When Fiber Cement is a Good Choice for a Deck Underlayment

• When installing a rigid surface: Fiber cement is an excellent choice when you plan to install ceramic tile or natural stone on your deck. It provides a ...

Fibre cement decking is a type of outdoor building material used for creating decks, patios, and balconies. It is a composite material made primarily from a mixture of wood fibers, cement, and other additives. This composition gives it the look of natural wood while providing the durability and low-maintenance properties of cement.

Fiber cement board is a durable, low-maintenance building material used for a wide range of interior and exterior construction projects. Composed of a mixture of cement, sand, and cellulose fibers, it’s known for its resistance to fire, water, rot, and pests.

Exterior Applications

Fiber cement board is most commonly used for a building’s exterior due to its strength and ability to withstand harsh weather conditions.

• Siding and Cladding: This is arguably the most popular use ...

A “60/60/60 fire-rated wall” refers to a wall assembly that has been tested and certified to resist fire for at least 60 minutes across three critical performance criteria. This rating is often a requirement in building codes, especially in commercial or multi-family residential structures, to ensure the safety of occupants and limit the spread of fire.

The three criteria in the Fire Resistance Level (FRL) rating are:

1. Structural Adequacy (60): The ability of the ...

Magnesium Oxide (MgO) board, often called magnesia board, is a versatile and high-performance building material that is used in a wide range of construction applications. Its unique combination of properties makes it a popular alternative to traditional materials like drywall, plywood, and cement board.

Here are the most common uses for MgO board, categorized by application:

Interior Applications
