During the cold season, sunlight streaming directly into the room through skylights increases the heat storage temperature of the floor and walls, reducing the frequency of heating use and achieving passive solar heating. Our roof skylight cover is made of thick galvanized steel plate and aluminum frame. We have added a 7.5 centimeter (2.9 inch) wide reinforcement at the center of the lid, making it more load-bearing and sturdy. Suitable for long-term indoor or outdoor use, can withstand harsh weather conditions and be widely used The sealing rubber gasket at the contact part between the flip cover and the bottom frame minimizes the noise caused by friction, ensuring a noise free operating environment and facilitating a quiet opening and closing process. At the same time, it can effectively prevent rainwater, dust, debris, etc. from passing through the gaps The manhole frame is equipped with four fixed holes and four expansion bolts, suitable for concrete structures. If used for wooden structures, you can purchase self tapping screws for installation. If you want it to be more waterproof, you can fill the gaps with glue The 90 degree rotating handle can easily close and open the lid, making it easy to use. Locks are easy to lock inside. It can only be opened and closed from the inside, not from the outside. The roof hatch has 2 air columns that can serve as buffers and shock absorbers, supporting the lid upwards and opening it, with a maximum angle of 90 degrees It can not only be used as attic skylights, escape routes, basement exits, emergency entrances, wellheads, cellars, and manholes, but also for home decoration, industry, commerce, schools, and more.
