Increased focus on limited energy consumption and reduced CO2 emission have led to even greater requirements for home insulation. The flip side to this coin is the reduced circulation of fresh air and the increased risk of moisture, fungus and allergies. This is why efficient ventilation is a necessity.
Natural ventilation through open windows is no longer enough. This technique results in an annual heat loss of up to 6,000 kWh for the average home making it impossible to meet new low energy consumption requirements.
The solution? Ventilation and heat recovery.
