| The specifications of Frame for ceiling with insulating building boards are following: |
|
| The width of the frame should be sufficient to provide a minimum nailing surface of 50mm. |

| The longitudinal and header scants are arranged in such manners that the boards can be fixed to form the panel arrangements. |
|
| The longitudinal scants to which the boards are mainly fixed are spaced at 30 to 45 cm centers. |
|
| The spacing depends on the width of the cut board in the panel arrangement. |
|
| All edges of the cut board units are supported either on the longitudinal or the header scants. |
|
| The framing centers should be 3 to 6 mm to allow space between boards where the joints in the board are to be covered. |
