Some roof sheet profiles are more than 1 metre wide as standard and we have tooling to make many such products. Often the rooflight pattern of an installation can include two or more rooflights adjacent to one another, depending on the daylighting requirements within the building. For other roof types, Barrel Vault Rooflights are available for daylight opening widths of 1000mm and 1200mm. Please contact us to discuss your requirements.
