material / RAL varnish
| roof frame | steel sheet, material no. 1.0037, varnished in grey RAL 7040 (more colours per request) or aluminium EN AW 6060 |
| multi-leaf damper | aluminium EN AW 6060 |
| pressure-controlling damper | aluminium EN AW 6060 |
Insulation
to avoid the entering of cold air, the diverting unit's roof frame is insulated on the inside and sealed by an insulated multi-leaf damper (DIN 1946-4 / DIN EN 1751)-
maintenance
The pressure-controlling damper as well as the multi-leaf damper can be accessed directly via the maintenance opening. Due to both dampers' special, sandwich-like manner of installation, they can be replaced easily.
