11512464 · 2022-11-29 ·

Robust multi-purpose, multi-layer, building construction tapes and building construction framing members and related wall assemblies are disclosed that comprise a sheet metal framing member (all profiles) in combination with a new and more robust type of multi-layer building construction tape for fire safety and sound reduction. The multi-layer building construction tape comprises a flexible thermal barrier layer attached to (1) a flexible intumescent material layer having a lesser width (thereby enabling flex-lock rollover) and/or (2) a resilient unfoamed cross-linked polyethylene layer. In combination, the thermal barrier layer is on a surface of the sheet metal framing member, whereas the thermal barrier layer is attached to the intumescent layer or polyethylene layer (as the case may be) such that the thermal barrier layer is between the sheet metal framing member and the intumescent layer or the polyethylene layer. The multi-layer building construction tapes disclosed herein slow and impede the spread of fire and smoke (during a fire) and also reduces sound transmission between adjacent rooms in a building.
