Windborne Debris Protection for Sunrooms Added to Mobile Homes
- Question: Does an existing mobile home with an existing screen room under an existing insulated composite panel or other solid roof require windborne debris protection when the screens are removed and new glass windows are installed creating a sunroom. There are 2 options. (1) Because of the way the code reads in section R301.2.1.2(1), a sunroom under an existing roof has an option. One is to provide windborne debris protection on the new glass windows of the sunroom. Two is to provide windborne debris protection over the existing openings in the exterior wall of the mobile home that occur within the sunroom. Windborne debris protection over the openings in the exterior wall of the mobile home will be accepted. The protection shall have product approval for material only. The installation of windborne debris protection on the mobile home will not be checked. The inspectors will verify that windborne debris protection has been installed on the mobile home or is on site to be installed.
- Question: Is windborne debris protection required for new sunrooms with new roofs when installed on new or existing mobile homes or on FBC compliant structures? The key here is that the sunroom is under a new roof and not an existing roof. Because of the wording in the code, sunrooms that are not under an existing roof do not have the options as permitted in question 1 above. A glass sunroom under a new roof is required to be windborne debris protected under section R301.2.1.2 Protection of openings. Therefore, a glass sunroom not under an existing roof shall be windborne debris protected. Sunrooms that have vinyl glazing do not require windborne debris protection.
- Question: Does a new sunroom with a new roof or an existing roof that uses vinyl glazing require windborne debris protection. Per section R301.2.1.2, the use of the word glazed, means glass. Therefore, a glass sunroom shall be windborne debris protected, but a vinyl glazed sunroom is not required to be windborne debris protected.
