The process for specifying your curved is very simple, however it is important to be accurate with any dimensions to ensure your radiator is built correctly, there will be opportunity to double check all figures against technical drawings before finalising the order.

Please follow the 3 simple steps below:
Work out the BTU output required to heat your room. To do this you will need to have details to hand of the room height, width and depth, as well as the type of window glazing (single or double). Use our online calculator to work it out.

Next choose a radiator that has a suitable output and meets the size requirements.
See our curved radiators.

Measure your chord and camber in the bay of your room.

Curved radiator measurements

If the radius of your curved wall is too small we won't be able to manufacture a radiator. The limit for 4 column is higher than the limit for 3 or 2 column because of the depth of the radiator.

 Use our curve check tool to see if your radiator can be manufactured.

To use the checker enter your measured chord and camber values in mm. Then select 2, 3 or 4 from the column selector. Then click the Submit button.

The mid radius of the radiator is:


The minimum values required are as follows:

2 Column 3 Column 4 Column
1000mm 1000mm 1300mm

Your radius value must exceed the minimum required value.
