Covertec Double membrane roof Double membrane roof maximizes storage volume of biogas plants The Covertec double membrane roof is an innovative, premium-quality roof system for the biogas industry. The system comprises two separate membranes manufactured from polyester woven fabric, PVC-coated on both sides, with a minimum weight of 27 oz/yd² (900 g/m²) and a minimum tear resistance of 900 lbs per 2 in. (4,000 N per 5 cm). The double-layer assembly is designed to even out pressure fluctuations in the container while the hemispherical and rotunda shape serves to maximize storage capacity. At the same time, the domed surface protects the cover against external weather action, such as heavy snow loads in winter.
