Aluminium windows from heroal are real energy savers and are therefore certified by the Passive House Institute Dr. Feist for passive houses.
heroal's own profile composite
heroal's own profile composite - heroal is the only company producing thermally insulated aluminium-PVC-composite profiles under external monitoring (ift Rosenheim, testing institute).
Modular composition of sealing zones
Modular composition of sealing zones - Thanks to the modular composition of sealing zones, individual customer requirements become possible - from high thermal insulation to passive house suitability.
Optimised isothermal curves
Optimised isothermal curves - Due to optimised isothermal curves, the thermal conductivity via the edges of the sealed glass pane is considerably reduced.
Low-E glass - To make sure that valuable thermal energy is not lost via the glass pane, our specialised partners will be pleased to give advice on the suitable insulating glass for your requirements. Depending on the required thermal insulation, coated Low-E glazing or triple glazing may be used.
heroal foam-filling process
heroal foam-filling process - In their modular insulation areas, heroal aluminium composite profiles are filled with PU-foams. The special process developed by heroal ensures that the insulation chambers are 100 % foam-filled, which leads to a better thermal insulation than other processes.
Patented insulating strip technology
Patented insulating strip technology - heroal's innovative insulating strip technology combines high capacity with minimal loss of heat. The geometry of the insulating strips reduces the energy flow and thus also reduces heat conductivity significantly, exceeding the current requirements of EnEV, the German energy saving regulation, by far.
