Our winter garden structures and sliding doors are made basing on Belgium CORIALIS systems – semi-finished products are imported from Belgium.
The Corialis system allows use of pinned connection in the eaves and the roof ridge, allowing roof pitch adjustment, and the integrated water removal systems (drip profiles) ensure tightness of the entire structure. Vinterglass experts each time conduct detailed analysis of strength of the designed structure, selecting solutions that will withstand the load (e.g., rafters additionally strengthened with steel or aluminium inserts). One of the advantages of this system is also the lack of necessity to change the existing roof elements, since owing to clever trim boards roof work was limited to the absolute minimum. The client can ask for a classic or elegant finish (the VICTORIAN system contains additional decorative finishing components).
We especially recommend Corialis Aliver 2000 (available also in the elegant Victorian option) and Aliver 5000+ systems.
