What Is Drywall and Where Is It Used?

Drywall is one of the most widely used construction materials in modern building, especially in prefabricated and eco-friendly homes. Lightweight, versatile, and affordable, it is commonly used in both new construction and renovation projects. In this article, we’ll introduce the key characteristics of drywall, its advantages, and the role it plays in modern prefab homes.

1. What Is Drywall?

Drywall (also known as plasterboard or gypsum board) is a flat panel made of compressed gypsum sandwiched between durable sheets of paper. The most common types include:

• Standard drywall – suitable for dry rooms

• Moisture-resistant drywall – specially treated to resist moisture, ideal for bathrooms, kitchens, and utility areas

• Fire-resistant drywall – contains additives that slow down combustion

• Acoustic drywall – enhanced sound insulation properties

2. Where Is Drywall Used in Prefab Homes?

Drywall is an essential part of the interior construction in prefab houses. It’s commonly used for:

• Interior partition walls – lightweight and easy to install, allowing flexible layouts

• Ceilings – conceals electrical or ventilation systems and supports recessed lighting

• Dry flooring – used in specific dry floor systems

• Wall cladding – pairs perfectly with insulation materials like rock wool for improved thermal and acoustic performance

  
  

At iHaus, drywall is used in many of our home models – both standard and moisture-resistant types, depending on the area (e.g., bathrooms).

3. Advantages of Drywall

• Lightweight and easy to install – ideal for fast modular construction

• Smooth surface for painting, wallpaper, or decorative finishes

• Fire resistance – especially with fire-rated panels

• Sound insulation – when combined with insulation materials

• Allows concealed installations – ideal for hiding wiring, lighting, or plumbing

  
  

4. Myths and Facts About Drywall

• ❌ "Drywall is fragile" – Not true. When properly installed on metal framing or OSB backing, it’s very durable

• ❌ "It can't be used in wet areas" – Moisture-resistant drywall is designed specifically for bathrooms and kitchens

• ✅ "Can it be reused?" – Not always after dismantling, but drywall is recyclable and eco-conscious
