MGO Board Fire Resistance Official Ratings

Magnesium Oxide (MgO) boards are officially rated for fire resistance using various international standards that categorize their non-combustibility and the fire-resistance duration of the assembly they are part of.

Here are the key official ratings and standards for MgO boards:

Reaction to Fire Classification (Non-Combustibility)

This classification determines if the material itself will contribute fuel to a fire, ...

Yes, Magnesium Oxide (MgO) board can be corrosive to metal fasteners and framing, but the risk largely depends on the board’s composition and the environmental conditions.

The primary factor is the presence of magnesium chloride as a binding agent, which is common in traditional or lower-quality MgO boards.

The Cause of Corrosion

The corrosion risk stems from the chloride content in the ...

Yes, some types of Magnesium Oxide (MgO) boards can “sweat” or leach fluid in humid conditions due to a process similar to deliquescence.

This phenomenon, often called “crying” or “sweating” boards, is a serious concern primarily associated with MgO boards that use magnesium chloride  as a binding agent, which forms magnesium oxychloride cement (MOC).

The Mechanism of Leaching/Sweating

The “sweating” is a ...

The material’s composition gives it a set of properties that make it highly suitable for furniture, especially pieces exposed to harsh conditions like kitchen, bathrooms, or outdoors.

• Unrivaled Durability and Strength: FCB is incredibly strong and resistant to breaking or cracking under stress. This robustness translates to furniture that can withstand heavy use and last for decades.
• Weather ...

It is generally NOT recommended to use a high-pressure power washer on fiber cement siding.

Why You Should Be Cautious:

• Damage: High-pressure water can damage the surface finish of the siding, leading to erosion or a chalky appearance.
• Water Intrusion: High-pressure jets can force water behind the siding panels, which can lead to moisture damage and potential issues with the underlying structure ...

The best and safest way to clean your fiber cement siding is with gentle methods and mild cleaners to protect the finish. It’s generally recommended to clean it about once or twice a year.

1. General Dirt, Dust, and Chalk

For routine cleaning and light buildup, you only need simple tools and a gentle touch.

• Tools:
  • Garden hose (for rinsing).
  • Soft cloth or a ...

The wood texture fiber cement plank is designed to provide the look of natural wood without the drawbacks, and this includes a high resistance to insects and termites.

Here is a breakdown of why this material does not typically attract or host termites and other pests:

 Does Not Attract Termites or Pests

The core material of fiber cement is what deters insects:

• Inedible Composition: Fiber ...

Fiber cement plank, including the wood-grain varieties, is highly resistant to moisture because its primary components are cement and sand, not organic wood fibers that swell and rot.

Here is a breakdown of how the plank resists moisture and the potential for water collection in the grooves.

Moisture Resistance Mechanism

Fiber cement plank is a composite material made from a dense mix of:

• Cement ...

Fiber cement board (FCB) is increasingly recognized for its use in furniture applications, moving beyond its traditional role as a building and cladding material. Its unique composition of cement, cellulose fibers, and sand/silica provides several advantages that make it suitable for both indoor and outdoor furniture

Fiber cement board (FCB) is increasingly recognized for its ...

In terms of impact resistance, fiber cement siding is significantly superior to vinyl siding. This difference is due to the fundamental composition and thickness of the materials.

Here is a detailed comparison, focusing particularly on resistance to weather phenomena like hail:
