HoSt offers single and double membrane roofs for biogas storage. Due to the special design of the membrane roofs there is minimal penetration of biogas. The membrane roofs are characterised by the minimum gas permeability, durability and maximum gas storage volume.
HoSt Insulated Bioroof®
HoSt also provides a double insulated flexible membrane roof. This roof is designed for projects where heat retention is particularly important and can be supplied to third parties or for projects where biogas is upgraded to natural gas. Heat loss is typically reduced by 60% compared with standard membrane roofs.
