Skylights are a great addition to any home or business. Unfortunately, a heavy downpour or a hailstorm can make quite a cacophony. Even traffic noise can be a nuisance. For this reason, many manufacturers offer double and triple glazed glass on their skylights and roof windows to help minimize the noise. If you’re looking to soundproof an existing skylight, an additional fixed (or hinged) polycarbonate panel can be added to increase its sound insulation.
