Answer: It is not recommended to use them interchangeably. WPC interior wall panels do not contain UV-resistant components, and they are prone to fading and aging when exposed to the outdoors for a long time. WPC exterior wall panels focus on weather resistance, and their surface texture and sound insulation performance are less suitable for meeting the needs of indoor scenarios. Interchangeability would affect the usage effect and lifespan.

🔧

Question: Are the installation processes of these two types of wall panels difficult? Do they require special tools?

Answer: The installation is relatively straightforward for both. The WPC indoor wall panels can be installed using methods such as gluing or locking, making them suitable for DIY operations.
