Glaverbel develops a glass to reduce heat in summer and warm in winter

When the heat of the Sun is most intense, Energy N ensures several hours of comfort in relation to other glazings. This model of Crystal rejects up to 58% of foreign solar heat, generating a decrease of the internal temperature that has proven to be a minimum of 7 degrees, compared to the temperature of an environment equipped with double glazing traditional. This thermal difference reached twelfth on tests involving the use of air conditioning. Similarly, the glazing with Energy N involves less time use of the systems of heating and air conditioning, made that entails lower energy costs and a reduction of emissions of CO₂ into the atmosphere. Traditional times more than double glazing to two isolates. All this with a transparent, colourless glass, of high light transmission; Energy N is lined with a double and ultra-thin, invisible layer of silver, element that lets the light in abundance.
