Providing transparent and verified data on our products and their impact is very important to us. This is demonstrated not only by our Environmental Product Declarations (EPDs), but also published studies on the topics of energy saving and living comfort, which were carried out by the independent Passive House Institute (PHI) in Darmstadt.
8.6% less heating energy
Compared to aluminium spacer bars, high-efficiency plastic spacer bars deliver much lower energy consumption, CO2 emissions and heating costs.
Warm edge and thermal comfort
The PHI study “Living Comfort” investigated how comfort and hygiene criteria can be defined and adhered to for windows in different climate zones.
