Educate yourself about different rating systems to help
select windows replacement as per your unique needs.
For instance, if you need windows that are good at
keeping heat in, you should focus on U-value or U-factor.
You should opt for windows with lower numbers. Similarly,
if you want windows that would stay visible during the day,
you may want to consider visible transmittance ratings.
Consider the cost of added features carefully. You may
have to pay extra money to enjoy certain features. For
instance, you may need to pay additional $20 to have
grilles between the glasses. The grille usually goes between
layers of insulated glass. Similarly, hardware-finish
upgrades may cost you more than $50. If you are in
hurricane zones, you may need windows with impact-
resistant glass, which may cost up to $325 or more.
