Nonostante Giemme System sia un prodotto studiato come seconda chiusura e non abbia quindi la necessità di essere certificato come serramento GM Morando ha voluto testimoniare la qualità del suo prodotto ottenendo la conformità alla normativa UNI EN 14351-1. Tale norma regola le performance dei serramenti per quanto riguarda la tenuta agli agenti atmosferici. La tenuta all' aria è garantita dalle guarnizioni trasparenti in policarbonato tra le ante e sui 4 lati, appositamente brevettate per eliminare ogni spiffero d'aria. Quando la vetrata rimane chiusa, le guarnizioni trasparenti ad “U” in policarbonato, poste tra un’anta e l’altra, si incastrano perfettamente con il vetro creando una parete trasparentissima e conferendo solidità all'intera struttura.

Regulations Conforming to European regulations Among the questions we receive most often are those relating to the resistance of atmospheric elements. Despite the fact that the Giemme System was conceived as a product for second closure and therefore doesn’t have to be certified like traditional windows and doors, GM Morando wanted to demonstrate the quality of the product by obtaining compliance to UNI ENI EN 14351-1.

This rule regulates the performance of windows and doors regarding resistance to atmospheric elements. Air-tightness is guaranteed by transparent, polycarbonate seals between the doors on all four sides. The product was specially patented by GM Morando to eliminate any draft or passage of air. The transparent, polycarbonate seals are shaped in the form of a U and placed between one door and another. When the glass doors remain closed, the seals fit perfectly with the glass creating a highly transparent wall and giving solidity to the entire structure.
