Hello, we have quite a large space in our roof that we are currently trying to ventilate to cool some hot spot areas of our house. We have installed a mechanical vent on the roof, we are putting in ceiling insulation, but we also would like to put some vents in the wall above kitchen to help provide airflow. We get a lovely breeze from the deck area, the living area is adequately cooled by ceiling fan. The dining area to the left is a hot spot, the kitchen can be and the study to the right of the kitchen. Where would I find some nice looking vents ( not plastic). Or any other suggestions?
