1. Waterproof WPC Interior Doors – Ideal for Humid Areas

WPC doors are highly resistant to moisture, making them perfect for kitchens, bathrooms, and high-humidity regions. Unlike traditional wooden doors that warp or swell, WPC maintains its shape and durability even in wet conditions.

Key Benefits:
No rotting or fungal growth – Unlike wood, WPC does not absorb water.
Low maintenance – No need for frequent repainting or sealing.
Longer lifespan – Resists cracking and peeling better than MDF or solid wood.

Comparison:

Feature	WPC Door	Traditional Wood Door
Water Resistance	Yes (fully waterproof)	No (requires sealing)
Maintenance	Low (no repainting needed)	High (regular varnishing)
Durability	15+ years	8-12 years (with care)
Risk of Warping	None	High in humid conditions

2. Eco-Friendly Composite Interior Doors – Sustainable & Stylish

For environmentally conscious homeowners, composite doors made from recycled wood fibers and plastic offer a green alternative. These doors reduce deforestation and minimize waste while providing excellent insulation.

Key Benefits:
Made from recycled materials – Reduces environmental impact.
Energy-efficient – Better thermal insulation than standard doors.
No harmful chemicals – Unlike some engineered woods that contain formaldehyde.

Comparison:

Feature	Composite Door	Solid Wood Door
Eco-Friendliness	High (recycled materials)	Medium (requires tree cutting)
Insulation	Excellent (better thermal retention)	Good (varies by wood type)
Cost	Moderate	High (premium woods)
Chemical Emissions	None (no formaldehyde)	Possible (depends on treatment)

3. Lightweight WPC Doors for Homes – Easy Installation & Versatility

WPC doors are significantly lighter than solid wood or metal doors, making them easier to install and handle. Their reduced weight doesn’t compromise strength, offering a practical solution for modern homes.

Key Benefits:

Easy to install – Ideal for DIY projects and quick renovations.
Gentle on hinges – Less strain, reducing wear and tear.
Versatile designs – Available in various finishes (woodgrain, smooth, painted).

Comparison:

Feature	Lightweight WPC Door	Solid Wood Door
Weight	20-30% lighter	Heavy
Installation	Simple (DIY-friendly)	Complex (may need professionals)
Customization	High (multiple finishes)	Limited (natural grain only)
Hinge Longevity	Longer lifespan (less strain)	Standard (may sag over time)
