When properly applied, intumescent lock protection should not affect normal operation of the lock mechanism.
Acoustic seals provide sound insulation by sealing gaps using materials that absorb and dampen sound waves to block sound transmission through gaps around doors, windows, and other gaps such as cable openings.
Threshold plates reduce sound transmission and improve the overall noise reduction of rooms by sealing gaps under the doors where sound travels through freely between rooms. An acoustic barrier is formed by the threshold plates which absorbs soundwaves.
Drop down seals operate with different activation mechanisms. They can be either mechanical activation, electromagnetic activation, or spring loaded. When activated the drop down seal extends downwards to seal the bottom of doors and retract when the door is closed.
Fire and smoke seals prevent the spread of fire and smoke by filling gaps between the fire doors and the door frame. Typically the smoke seals block smoke from spreading before the fire seals activate and provide the full passive protection.
Fire rated air transfer grilles use one of two mechanisms. One of the mechanisms is fire dampers that close when exposed to extreme temperatures from a fire. The 2nd mechanism is intumescent materials that expand when heated to seal the opening. Some fire rated air transfer grilles combine both mechanisms for enhanced protection.
