ThermAcoustic™ Wall
(UL Design No.U210)
U210 provides an additional 2 hrs. of UL rated fire protection, as compared with double-layer gypsum shaft wall assemblies.
Construction with gypsum-based shaft material becomes cost prohibitive at the 3 hr. and 4 hr. ratings, based not only on material cost, but but also the added labor and time required for field assembly of each multi-layer, multi-channel wall.
