Increase the energy performance of your home

Smart and automatic shading from Harol not only improves the energy performance of your home, but also contributes to a pleasant indoor climate. Here are three ways our products achieve this:

  1. Heat protection: Roller shutters, screens or outside venetian blinds reduce incident sun rays. This prevents excessive heating of the home. This reduces the need for air conditioning, resulting in lower energy consumption.
  2. Insulation: External sun screens serve as an extra layer of insulation, resulting in less heat loss in the winter and the home heating up less drastically in the summer. This contributes to better temperature regulation of the home.
  3. Regulation of daylight: Screens and outside venetian blinds help to effectively regulate daylight. This allows you to make optimal use of natural daylight and reduces the use of artificial lighting. This reduces the total energy consumption of the home.

Why prevent overheating?

On sunny days, the indoor temperature in well insulated homes can rise considerably. This also happens in poorly insulated homes. Overheating is not only unpleasant, but it also reduces productivity and is harmful to health. Overheating can also lead to the use of energy-intensive cooling systems, which runs counter to the global ambition to save energy.

Why natural cooling

Our mission statement, “We Believe in Natural Cooling,” lies at the heart of all our efforts. We consider smart sun screens to be the most natural and energy-efficient way to block heat. Compare it to a tree providing shade: just as you seek natural cooling under the branches of a tree, sun screens keep the sun out and your home, patio and workplace pleasantly cool. They offer natural air conditioning for your home which is healthy but also environmentally-friendly.
