A videographer. Videography refers to the process of capturing moving images on electronic media (e.g., videotape, direct to disk recording, or solid state storage) and even streaming media. The term includes methods of video production and post-production.
Insulating around can lights. There are some can lights in my kitchen that according to the Home Inspector shouldn't have insulation right around them in the attic (which they do). He suggested building some little boxes out of duct board to cover them. They do leak quite a bit of air as it is now.
Insulation is made of materials that are poor conductors, such as glass, plastic, or rubber. These materials are used in an attempt to keep an electrical current within safe boundaries. For example, the plastic coating on an electrical wire acts as insulation and is designed to keep the electricity inside the wire.
