With no venting capabilities, this option provides the best seal and the greatest degree of energy efficiency. The vinyl construction offers you improved insulation over the aluminum frames that exists in many homes, and will help to eliminate drafts and leaking.
You will also notice a decrease in your energy costs as a result of our two key thermal features: argon gas and low E glass.
Argon gas is slower moving than oxygen, and when placed between the panes allows for less temperature transfer, preventing the loss of heat in the winter, or cooling in the summer.
Low E works to reflect the hot rays of the sun out during the warm months, and reflects the warm air from your furnace back into your home in the cold months.
