Thanks for the visit, review and positive criticism. I think you meant the ceiling. Before our renovation we actually had the ceiling boards that we usually see in many places but where defeated by extreme temperature that often reaches 40 degrees in that part of Namibia. The corrugated roof underneath the solar pvc on top of the roof and an internal spacing of half a meter between the heat shield and the peralol-impregnated zinc ceiling actually cooled the place. Thanks to the advice by our Bavarian based colleagues. It was a costly replacement and we were also skeptical as we were not familiar with it but after the installation- no client has ever complained about heat todate . The aircons BTU units were also increased, I hope you adjusted them accordingly.
