There are a number of ways to save energy. One of these is Grinotex^®. Sealing lips allow the external venetian blinds to close fully. This very durable external venetian blind system is extremely weatherproof thanks to the resilient steel lift and drive chains, the slat support connections made of stainless steel cable with UV-resistant plastic casing, the stable guides and the solid bottom rails. Finally, Grinotex^® can be used in places where intrusion protection is required due to the safety locking device, which works in any position. The safety sensing edge prevents the external venetian blind being damaged when encountering obstacles. The Grinotex Sinus^® version has a unique and impressive slat design. The robust and particularly kink-proof slat profile is also extremely elegant and adds that ideal touch to the facade of the building. As well as featuring the tried and tested characteristics of the Grinotex^® version, the Grinotex Sinus^® version also optimizes use of daylight and glare protection.
