"This system solution is a pitched roof system with thrust protection, for roofs with slopes of 15 to approx. 35°. From this degree of roof pitch, shearing protection is necessary to prevent erosion and problems that can arise during heavy rainfall. No special requirements have to be met for the thrust protection system, it can be used on all roofs with a pitch of up to approx. 35°. The thrust protection is available in different units of measurement and is therefore easy to adapt as required. This system solution can also be used for roofs in special shapes and with much greater roof pitches. However, these cases require very detailed planning, which needs to be done in collaboration with ClimaGrün’s experts. When it comes to complex green roofs with special pitches, ClimaGrün is a specialist."
