The use of materials to make the walls pretty much choice. One of the best material ever, especially for wall panels are wood. However peru note, not all of the wood can be used for this purpose. Some of the wood has a very nice little moisture content used for wall panels for interiors.
But if it is hard to find wood with the above conditions, you can order wood that has been dried first, to near the limit of maximum recommended moisture content. This is so the durability of the wood may take longer than some wood that is not dried first.
In addition, any timber used for the purposes of the wall panels should have a pretty good texture, smooth and neat. This is because the use of wall panels is intended for special rooms, such as living room, family room, or dining room.
