The evolutionary Darwin shed is the perfect design if you want the look and feel of wood with all of the benefits and ease of plastic. A Keter shed provides ample airflow by having specifically placed vents but, as with any shed, condensation can form. If you do see signs of condensation here are hints to help you to protect the contents of your shed. To prevent condensation inside your shed, wherever possible, do not allow any excess moisture inside the shed. To do this try and ensure all equipment inside the shed such as camping gear or sporting goods are cleaned and dried before storing them in the shed. Try to let as much air inside the shed on cooler, dry days, by opening the shed doors. This will help the air circulation inside the shed and will drop the humidity level inside. Please note the durable material that all Keter sheds are made of will not be affected by moisture or condensation as part of the Keter no maintenance promise. Eco-friendly: Evotech material is long-lasting and fully recyclable, providing the look of wood without using any real wood. The ventilation grille prevents odor-causing moisture
