There are 3 main points to achieving fire rating levels (FRL’s), party wall sealer assists by helping with all 3. Structural adequacy, the means of the structure being able to hold up other components. Integrity, the means of resisting fire and hot gases such as smoke directly. Lastly insulation, the ability of the structure to maintain temperatures below specified limits on the other side of the wall. Fireseal assists by creating a heat resistant barrier with high density insulation, which covers 22 points of FRL’s directly and stops flame from being able to get through to the next dwelling, thus indirectly assisting with structural adequacy.
