Could privacy films have a negative effect on thermal insulation?

With correctly selected and installed privacy films, no negative effects on thermal insulation should be expected. In fact, many privacy films can help to keep the heat in the room by reducing direct sunlight. This can reduce the need for air conditioning and thus contribute to an energy-efficient indoor climate.

However, it is important to choose a film that is specifically designed for this functionality. Some films provide both privacy and additional thermal insulation by reflecting heat or having insulating properties. To maximise the desired energy benefits, it is advisable to check the specifications of the films and seek professional advice if necessary. This will ensure that the optimum choice is made to maximise both privacy and energy efficiency.
