Range of Sizes

Available in sizes from 1050x1050mm up to 1800x1800mm which stagger up in 150mm increments. If your size doesn’t appear here, we will be happy to assist with any query.

Measuring Guide for fitting to builders upstand

Acceptable tolerance:

  • Internal builders upstand = (dome size – 150mm) +20/-0
  • External builders upstand = dome size +40/-20mm

If you are installing on your own upstand, the upstand height should be 200mm. For example, on our website is a drop-down menu for you to order from, ff you choose 1050x1050mm this would mean your structural opening would be 900x900mm. The builders upstand should be 75mm in width.

Measuring Guide for domes with PVC kerb

Measure internal roof opening

Acceptable tolerance = dome size +20/-30mm

If you purchase with an upstand then the size you order from our website’s drop-down menu will be the structural opening measurement (shown in the diagram above in red). Please note this does not apply if you fit on your own upstand.
