What is the difference between allowable limits and minimum thickness?
• Damage Depth vs. Window Thickness: Limits and minimums are dictated by the manuals. The maximum allowable damage depth is a gauge for mandatory window repair or replacement. When damage is removed, the amount of material removed by grinding and polishing is a bit more than the damage depth. When that amount of acrylic is removed, a measurement is taken to insure the minimum window thickness is still present. Minimum thickness of the window has to be preserved or the window must be replaced. Likewise, for the repair option to be approved, the damage cannot penetrate below the window’s minimum thickness. • We will assess the damage status before recommending the work.
