        "text": "The rough opening should typically be about 2 inches wider and 2 inches taller than the actual window unit dimensions, though exact manufacturer specifications always dictate final framing. This additional perimeter space provides roughly 1/2 to 3/4 inch of clearance on all four sides. That clearance allows us to shim the window frame perfectly square, level, and plumb, compensating for any minor out-of-square wall studs. It also creates the necessary cavity for proper low-expansion insulating foam and weatherproofing flashing tape without binding the window frame.",
