How To Measure Up For A Metal Radiator Cover

With overall productivity down in light of recent events, now might be a time to start preparing for future projects. 

This blog about measuring for a metal radiator cover has been updated in March 2020 with updated information and images. 

We're regularly asked how to measure up for a metal radiator cover.  It's a pretty straightforward exercise, but we thought it would be extremely useful if we were to post some simple instructions to help explain the process quickly and clearly.


Measuring For A Standard Floor Standing Flat Top DeepClean Radiator Guards

First of all, you will need a few basic items ready before you start;

  • Tape Measure
  • Pen & Paper, or even better a Contour Survey Sheet
  • Camera/Camera Phone (just in case there are some tricky bits you want us to be aware of)
  • A spirit level if you think the floor or wall may not be too level.

Once you have got all of this to hand, you are ready to measure your radiator for a metal radiator cover.

The process is to measure the length (width) of the radiator, the height from the floor, the depth from the wall and measure up any skirtings for the factory made cutouts (this eliminates site cutting and makes your life easier when installing the radiator covers).

Step 1 - Measure Up The Guard Length / Width

Carefully measure the widest point of the radiator, this is normally from valve to valve.

Once you have measured this length, add at least 50mm to give you tolerance either side for the 20mm fixing return that the Deep Clean guard has on the frame.  Write this dimension into the length box on our site survey form.


How to measure the radiator width for your radiator cover Add 50mm to the overall length of the radiator, including valves, to give enough clearance for the radiator cover to easily fit over the radiator.


Step 2 - Measure For The Cover Height

To get this measurement you need to add 50mm to the highest point of the radiator.

Always make sure you check both sides of the radiator to make sure the floor isn't running out.

If your floor isn't level we can manufacture a radiator guard with a tapered plinth to give you a level top.  You may want us to survey this for you.

Step 3 - Measure for The Radiator Cover Depth

For the Deep Clean guard, our standard tolerance is 65mm deeper than the deepest point of the radiator. On a 90mm deep radiator, you will have a 155mm deep guard.

The 65mm Tolerance is due to the plinth detail we have on our guard which allows the door when opened to lie flat on the floor.

CAreful measurement of the depth ensures a good fit for the radiator cover

Step 4 - Measuring For Skirting Cutouts

If you require a cut out for the skirting board or vinyl flooring (cap and coved) we will require the height and depth of this along with the radius of the cove so we can achieve the detail below.
If Anti-ligature we recommend the skirting be cut back and butted up to the side of the guard.

If you have surface mounted pipework then provide us with the height and depth + 10mm tolerance to each. As this will generally be covered up by Pipe boxing.


Take Care When Measuring For Skirting Cutouts It's important to carefully the skirting board on both sides of the radiator. It isn't unusual for them to not be 100% the same!


Do You Want Us To Survey Your Radiator Guard Project?

We offer site surveys free of charge as an integral part of our comprehensive service.

Our surveyors, all having considerable installation experience, will identify the correct size and quantities of products required. They will take note of any special requirements that are necessary including cut-outs.

Modifications can then be programmed into manufacture, making the installation process more efficient. Contour’s team of surveyors can work with you to suggest innovative and alternative design modifications on your original concepts, helping you reduce installation time and costs.
