Sage Interior Finishes specializes in fire-treated backing and blocking in Des Moines, Iowa. Blocking refers to installing a short piece of stud (block) horizontally between the vertical studs. The block reinforces the vertical studs and can act as a fire-stop or mounting block for heavy fixtures.
Backing refers to frame lumber installed between the wall studs to give additional support for drywall or an interior trim related item, such as handrail brackets, cabinets and towel bars. Backing allows for items to be screwed and mounted into solid wood rather than weak drywall that may allow the item to break loose from the wall.
We utilize fire-treated wood for backing and blocking, which has been treated to make the wood burn more slowly than untreated wood. This treatment can also help reduce flame spread and smoke development.
