Norbreck Expert/Design Tip

When ordering radiator valves, always check your pipework first! Straight valves like these are only for pipes coming up through the floor. If your pipes come out of the wall, you will need "Angled" valves instead. For a truly high-end finish, don't leave the copper pipes exposed; we always recommend using matching pipe shrouds (sleeves) in the same finish as your valves to create a seamless look from the floor to the radiator.
