Manufactured with an extruded polystyrene foam core and a special coating on both sides, Jackoboard® construction boards form an ideal base for tiling. The surfaces of the Jackoboard® system provide an extremely strong bond and can be used on virtually any substrate. The boards are waterproof, thermally insulating, lightweight and very strong.
Premium Inverted Roof Insulation
An inverted roof construction places thermal insulation above the waterproof layer. This maintains the waterproof membrane at an even temperature and protects it from the damaging effects of UV radiation
