System Board 65 is designed for new build and refurbishment applications, Castellated panels are laid over foiled insulation forming a grid, pipe loops are then simply pushed in between the castellations.

This system ensures even centres and is particularly helpful when installing pipe at 150mm and 100mm centres. A minimum standard screed thickness of 65m is recommended, although some pumped screeds can be lower and will offer faster drying times.
A Warmis screed system will provide the highest heat output of all systems, furthermore, they are the cheapest to purchase, as in most cases the pipe loops are secured to foil faced insulation and then covered with a 65mm screed, this method effectively turns the building slab into the heat emitter.
