What affects the price

Replacing your windows with impact-rated glass involves a few variables that shift your final total. First, the size and number of openings in your home play the biggest role, as custom measurements require more material and labor. The style of window you choose—like single-hung, casement, or sliders—also changes the math, as does the frame material, such as vinyl versus aluminum. If you live in an area with stricter wind-load requirements, that might necessitate thicker glass or specialized hardware.
