Peace, mercy, and blessings of God be upon you. Who has the expertise or experience to help us with a solution? I have a ceiling in the villa opposite the stairs. The property owner made a glass ceiling (skylight) to let sunlight into the villa. A beautiful idea that gives the house an atmosphere. But the problem now, with the start of summer, the upper annex has become very hot, and the air conditioning in the house in the annex and the first floor does not cool due to the intensity of the heat. Has anyone been through the same experience, and would insulation for awnings work by covering the top of the ceiling to prevent heat?
