There are possible glass combinations according to the purpose of the building and its geographical location.
North (northeast,northwest) location
Low-E glass is recommended. It prevents heat escaping through your windows to the cold outdoors. Low-e glass has an invisible coating which dramatically reduces heat transfer and reflects interior heat back into your room.
East, West and South location
We recommend multifunctional glass. It keeps warm in the winter and cool in the summer, offering year-round comfort. It can be used for roofs and vertical glazing and is perfect for greenhouses It reduces the heat loss, has excellent solar protection and good aesthetics, corresponding to the rest of the glazing.
