Not usually. Well-specified double glazed lanterns generally meet the limiting values for rooflights. Triple glazing is an upgrade, not normally a requirement. Your building control body can confirm for your project.

Yes, the glass is roughly 45% heavier. Plan for extra hands or lifting equipment on larger lanterns.
