Ventilation in the attic/loft calculator


The calculator is used to calculate the ventilation capacity in an attic or loft for the minimum, normal and extreme thermal conditions of the environment depending on the area and height of the room and the roof pitch. The fan removes warm air from the room and should be mounted at the highest possible point for the best efficiency.
Enter the length, width and height of the room at the highest point. Choose whether the roof is flat or pitched.
