Opening Rooflight

How to specify Vario by VELUX rooflights

• Structural Opening - the structural opening (hole in the roof) has to be +30mm larger than the clear internal for both the width and length

• External frame measurement - this measurement is +250mm larger than the clear internal for both the width and length
