A glass skylight can completely change the way a home looks and feels. It can bring natural daylight into dark staircases, living rooms, corridors, bathrooms, atriums, and other areas where conventional windows may not provide enough light. However, glass skylight installation is not simply about placing glass on the roof. Proper design, glass selection, structural support, waterproofing, heat control, drainage, and professional installation all play an important role in achieving a safe and long-lasting result.
