Meet the Jackoboard Aqua Flat Centre drain, your go-to solution for level access on suspended timber floors. Made from 20mm thick extruded polystyrene foam, this board is not only water-repellent but also features a special coating on both sides, allowing you to lay tiles directly on top. With excellent thermal insulation, high compressive strength, and a cleverly incorporated fall for drainage in the centre, it's the perfect blend of functionality and ease.
