Radiant PEX-AL is a composite pipe engineered for radiant floor heating. It's proven, long lasting and maintenance free. Installers like it because it's lightweight, durable and can be shaped to fit any jobsite. The aluminum layer protects boiler systems against corrosion and it has superior temperature and pressure ratings. RadiantPEX-AL pipe and fittings are manufactured to American Standard Testing Methods for requirements and test methods for materials, workmanship, dimensions, environmental stress, cracking, sustained hydrostatic pressure strength, thermo-cycling resistance and bend strength, among other tests. RadiantPEX-AL meets or exceeds these specifications.

Zone valves are used to control hot and chilled water in heating and airconditioning
systems. Coupled with an electro-thermal control actuator and
managed by a room thermostat, they allow automatic on/off control of the
hydronic circuit on which they are installed.
Their special feature is their compact size and they can therefore be installed
almost anywhere including baseboard or directly in fan-coil units.

Distribution manifolds for radiant panel systems are used to optimally distribute the heating fluid in floor
heating system circuits and ultimately improve the control of heat emission from the panels. The manifolds
ensure that the flow of each circuit is regulated precisely and also control the shut-off, venting and automatic
removal of air from the system.
