HELLA attaches great importance to energy saving and designs its products in such a way, that they are efficient in this field.

 

3 important terms of energy saving are

  • U (U-value): Thermal transfer coefficient in W/(m²K)
    The U-value (former k-value) specifies how much heat capacity flows through a component area of one square metre at a temperature difference of 1 K (1 Kelvin is 1 °C). With regard to the product only.
  • Psi-value: Linear thermal transfer coefficient in W/(mK)
    The Psi-value specifies how much heat capacity flows through a component with a length of 1 metre at a temperature difference of 1 K (1 Kelvin is 1 °C). Different installation details according to DIN 4108-2.
  • fRsi: Temperature factor
    Specifies the difference of minimum interior surface temperature to the exterior air temperature/difference of interior temperature to the exterior air temperature ratio.


Saving energy

 

Sustainable energy efficiency
 

Prevailing outside temperatures find their ways into all buildings. As long as these temperatures are agreeable, we feel comfortable indeed. Heat or the cold, however, need to be locked out. This requires cooling or heating energy. However, thanks to modern building and home technology this energy requirement can be reduced significantly - and hence costs can be lowered. HELLA sun and weather protection products reduce the energy requirement to create a comforting atmosphere by up to 50 %! There is a pleasant side effect: They are thereby protecting our nature.

  • Less COOLING ENERGY in the SUMMER

  • Less HEATING ENERGY during WINTERTIME

 

 

Outdoor Blinds & Venetian Blinds

 

RaffstorenRaffstoren
Heat can enter the living space without hindrance.    The temperature inside the room is unpleasantly high.The air circulation between outdoor blinds/Venetian blinds and windows largely eliminates heat transfer via convection.
 RaffstorenRaffstoren
In cold temperatures windows and glass facades function like a thermal bridge: The warm air escapes and it becomes unpleasantly chilly in the living area.When the outdoor blinds/Venetian blinds are closed, an air cushion is created in front of the glass, which prevents circulation of air. As a result, the warm air stays inside the living area and keeps the cold air outside.

  

 

 

Roller shutters

*Special feature daylight roller shutter: Light spreads evenly through the room. Heat, cold and noise remain outdoors.

Heat can enter the living space without hindrance.    The temperature inside the room is unpleasantly high.Special designs provide ideal thermal protection due to a reflective shimmering effect and an aluminium-metallised surface.

As a result the warm air stays inside the living area and keeps the cold air mostly outside.
