The question of whether MgSO4 board is a structural sheathing material is complex and depends on the specific product and its code approval, but the general answer is Yes, specific, high-density MgSO4 formulations are engineered and approved for use as structural sheathing

Here is a breakdown:

1. Structural vs. Non-Structural

• Sheathing is a board or panel material covering the outer wall framing (studs).
• Structural ...

Magnesium Sulfate (MgSO4) Board is unequivocally more suitable for high-humidity and exterior applications than Magnesium Chloride (MgCl2) Board.

The reason is the absence of high concentrations of chloride ions in the  (MgSO4) formulation, which eliminates the core problems associated with  (MgSO4)boards in wet environments:

1. Corrosion: (MgSO4) boards are non-corrosive to metal fasteners and steel frames, whereas (MgCl2) boards can leach corrosive chloride-salt ...

An MGO (Magnesium Oxide) board is generally considered a safe and environmentally friendly building material, often marketed as a greener alternative to traditional options like gypsum drywall and cement board.

Here is a detailed breakdown of its safety and environmental attributes, along with a crucial safety consideration：

Safety and Health Profile

MGO boards have several characteristics that make them a safe choice for ...

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 ...

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 ...
