MPT Deck Plug is made of inorganic fibers derived from basalt, a volcanic rock, with thermosetting resin binder. Advanced manufacturing technology ensures consistent product quality, with high fiber density and low shot content, for excellent performance in firestopping assemblies. MPT-DP is a high density mineral wool manufactured in a trapezoidal shape to fill voids in metal decks in Head-of-Wall (HWD) where deck flutes are perpendicular to adjoining fire-rated walls.

Features

• Precision Fit. Manufactured in strips shaped to exactly fit the deck flutes. Just cut the length required. Quick and easy to use, no guessing at angles or need for templates.
• Superior Substrate Performance. The high density provides a rigidity performing well as a substrate to firestop spray allowing for consistency of coverage and less potential for overspray.
• Light Weight, Low Dust. Easy to handle and fabricate, MPT-DP is easy to cut with a knife. No sawing is required.
• Noncombustible. MPT Deck Plugs is rated as noncombustible in accordance with ASTM E136 and CAN4-S114-M.
• Mold Resistant. MPT-DP does not support the growth of fungi.
