In today’s economy, it is essential to conserve energy, not only for cost purposes, but also for environmental reasons. Heat Shield 19 vinyl replacement windows are the only product that control all aspects of glazing performance: visible transmittance, shading coefficient and R-value, as much as 74% higher than popular types of low e glass sold in many windows.
