Insulation is a major problem when living in the city. Double glazing gives sound proofing and thermal insulation. Protect from the cold in winter and keep the air-conditioned coolness in the in summer.
About 15% of the total loss (or gain) of heat in house is through windows. Double glazing conceivably reduces fuel bills by cutting the heat/cold loss from each room. This saving recovers quickly the higher cost of installation.
