This background is the perfect choice of panels for terrarium, vivarium and tank backing. It is suitable for both small and large enclosures and is highly resistant to mould. The background creates a thick wall of grippy material that plants and animals can use to climb. The cork is easy to work with as well and can be used to pin decor, creating interesting vertical habitats. It’s also suitable for both high-humidity and arid habitats, so you can be sure it will fit into whatever you’re building. Cork is a great vertical foundation and a classic of UK reptile keeping as you can easily pin all sorts of things to it, including live plants, climbing decor and even reptile supplies like frozen food. It’s easy to work with and can be cut into almost any shape with relative ease, so you can get creative with it. The earthy tone and texture of the panels also create a nice natural look that will look better than a terrarium with no background or a flat image. Cork works great in high-humidity environments if the panels are fixed to the walls of your enclosure with a high-quality sealant. The cork will even absorb and rerelease some moisture, like some substrates, contributing to the overall humidity. Cork is resistant to mildew and other types of mould, so as long as you clean it regularly it should be fine in even the most naturalistic terrariums.If you just want to cover the back wall of your terrarium we recommend measuring the wall and buying a tile slightly bigger then it cutting to size. If you want to create something a little more complex we recommend buying the larger sizes of tiles and then cutting them to size. In particularly large enclosures you may find you need to buy several panels to cover a full wall.
