- EASY ACCESSIBILITY FOR MAINTENANCE AND OVERHAUL ACTIVITIES

The Air Blown Cover is an innovative double membrane roof with a relatively large, variable gas-storage volume, for biogas installations and other purposes. Its shape and membrane pressure mean that weather influences have little effect on the AB Cover.
