Parapet walls
The minimum thickness and maximum height of parapet walls should be as indicated in the diagram below.
If the criteria indicated below cannot be attained design calculations should be submitted to indicate suitability.
Type A cavity wall
Thickness | Parapet height H to be not more than |
---|---|
t1 + t 2 equal or less than 200 |
600 millimetres |
t1 + t 2 greater than 200 equal to or less than 250 |
860 millimetres |
Type B solid wall
Thickness | Parapet height H to be not more than |
---|---|
t=150 | 600 millimetres |
t=190 | 700 millimetres |
t=215 | 860 millimetres |
Note: t should be less than or equal to T
Note, the above guidance relates only to structural aspects of parapet wall design.
Further advice should be obtained with regard to moisture penetration.
