There are many potential applications with Onboard panels, although they are most commonly used within showers, wet rooms, steam rooms and swimming pools.

Their versatility allows them to be used on metal and timber stud work, or on top of existing floors and walls to cover unstable and uneven surfaces. In addition, their lightweight design means there are no extra load requirements and they are very easy to handle and cut.

The cement coated design combined with the strengthened fibreglass mesh, provides high thermal insulation properties. This will ensure minimal heat transfer to adjacent surfaces, making them ideal for use below electrical underfloor heating.

These panels are manufactured to the highest specifications and have become the industry benchmark for stable, impervious and durable tile backer boards.

The Onboard range is suitable for use in conjunction with a tanking kit, which will create a completely waterproof surface for use beneath ceramic, porcelain, natural stone and mosaic tiles.
