Skylight shades are not only valuable in the summer, but vital in the winter. As you heat your house in the winter, that heat is rising and escaping through that skylight. So you are paying higher energy costs that are escaping from your home. A skylight shade is made from cellular shade or honeycomb shade material, so it acts as a barrier to keep unwanted heat out, but also to keep valuable heat in! It is estimated that home or business owners can lose 2-5% of their heat through skylights in the winter. So rather than paying higher prices in energy bills for years to come, invest in a skylight shade.
