fluid or smooth shaped geometry free of added edges overlaps or protrusions however a flush attachment as described above is not essential to the success of the present invention it is possible that more than two slots could be used in the type of embodiment shown in fig4 or even as few as one the purpose of having the intumescent material located in the slots 34 and 36 is to create fire protection areas when the intumescent material 40 and 42 becomes hot it will expand rapidly into the open areas around it much as in the embodiment shown in fig1 3 this expansion will help to create a barrier or seal substantially preventing fire heat and smoke from moving from one area of a building to another for at least some period of time fig5 a and 5b illustrate other embodiments of a fire rated wall component 46 here the wall component takes the form of a vent the wall component 46 has a lower ventilation area 48 which includes a set or series of ventilation holes these holes which are hidden from view in fig5 a and 5b but are shown in fig7 allow air and other matter to travel between floors and rooms in a building or between the outside of a building and the interior of a building as can be seen in fig5 a a strip of intumescent material 50 is attached adjacent to and above ventilation area 48 the top surface of the intumescent material is flush with the top surface 54 of wall component 46 this allows for easy installation and use of a flat strap 52 a flush fit however is not essential to the success of the present invention the.
