2. The Directions.
Without directions, we might find ourselves toasting pop tarts with the wrappers on, or using blow dryers under water. They keep us safe. That doesn’t mean you can expect your contractor to read them. Recessed lights that are not rated for direct contact with insulation usually have a warning label on them that explains that insulation must be kept at least 3″ away. I like to give installers the benefit of the doubt and assume they just missed the large warning during the entire time they were installing the light. There is no way contractors consciously dismissed the warning. Right?
