Sloped, vaulted, and cathedral ceilings are different names for essentially the same ceiling configuration. These ceilings are very popular in newer homes and remodeled homes, and they certainly add dramatic visual interest to a room. But because there is little or no attic space separating inside and outside air, proper insulation is especially important.
Many cathedral ceilings will require that insulation be installed around recessed light fixtures. There are some important safety measures you should be aware of when working with insulation around light fixtures. Be sure to review the Special Considerations for the information you need to complete the installation without creating potential fire hazards.
It's also a good idea to wear a work helmet when you're installing ceiling insulation. This can help you avoid injuring yourself on exposed framing members such as ceiling joists, exposed nails and other hazards.
