1 Energy renovation of the window opening

2 Energetic requalification of the window opening Recently, the attention towards energy saving, renewable energies and the rational utilization of energy resources has been exponentially growing. Italy, as many other western countries, has a negative energy balance, so it is forced to find sources of primary energy, such as oil, methane gas or charcoal abroad. To improve this situation, everyone can contribute to the energetic requalification of the private houses. According to recent studies carried out by ENEA, the more affordable energy saving interventions - thinking to value for money - are the requalification of the window frames (see Table 1): insulation of the old roller shutter box and installation of new weatherstrips. Fig 1. Renova system In this regard, Roverplastik promotes the requalification of the window opening with two types of interventions: Renova system for the roller shutter box requalification and the kit for the window/door frame renovation. The table below shows the payback time of the energetic requalification. It is calculated considering the price of the fuel, the average cost of each material used and the obtained energy saving, without considering the possible deductions. Fig 2. Installation of weatherstrips Climate zones Interventions D E F Payback time Weatherstrips Less than 4 years Requalification of the roller shutter box Less than 6,5 years Less than 4 years Table 1 98

To improve this situation, everyone can contribute to the energetic requalification of the private houses.
