What materials are vertical blind slats made of?

Vertical blind slats are made from various materials to suit different preferences and needs. Some common materials used for manufacturing vertical blind slats include: 

1. Vinyl/PVC: Vinyl or PVC (Polyvinyl Chloride) is one of the most popular materials for vertical blind slats. It is durable, easy to clean, and resistant to moisture, making it suitable for areas like kitchens and bathrooms.

2. Fabric: Fabric slats add a softer touch to the window treatment. They are available in different colors, patterns, and textures, allowing for more design versatility. 

3. Solar Screen Fabric: Solar screen fabric slats are designed to filter and block sunlight effectively. They help in reducing glare and heat, making them ideal for sun-facing windows.

Each material has its own advantages and considerations, so when choosing replacement slats or new vertical blinds, it's essential to consider factors such as the room's purpose, style preferences, and maintenance requirements.
