The thermal insulation panels Aqua Top by Joma Thermoboden are products with high quality and functionality which also respect ecological aspects. The panels are laid in a system with tongue and groove in deck area and insulation. Thus, they are custom-fit and create no thermal bridges. The vapour diffusion via channels in the EPS eliminates the need for film. The panels feature a quality-proven EPS insulation and are extremely light-weight. The deck area is water resistant so that the panels can also be laid under leaking roofs. Ecology is regarded from two sides: the panels are completely recyclable and energetically redeem after about only three years.
