How much does double glazing reduce heat?
Double glazing works by trapped air between the two panes of glass acting as an insulator, reducing hear loss from condition from the inner glass to the outer glass. Using efficient double glazing can reduce the heat loss from windows by over 50%.
Does double glazing make house hotter in summer?
