What are Sewatek's products used for?

Our products allow service penetrations to meet their requirements for fire resistance. 

A structure's fire resistance rating denotes the number of minutes the structure can withstand a fire. For our part, the structure's load bearing capacity (R) is not that crucial as a Sewatek service penetration does not significantly affect the structure's load bearing capacity. Instead, our products focus on the structure's integrity (E) and thermal insulation (I). For instance, the fire resistance requirement EI60 means that the structure must retain its integrity and thermal insulation capabilities for 60 minutes in a fire situation. 

Fire resistance requirements come into play when a structure is required to create a fire compartment. A fire compartment is a fireproof space that can withstand a fire for at least the time period specified by the structure's fire-resistance rating. In an apartment building, for example, each apartment forms its own fire compartment. When electrical wires or water pipes or other such services are fed from one fire compartment to another, the penetrations must be sealed to match the fire-resistance rating of the wall. These penetrations require a firestop. 

A firestop brings the service penetration's fire-resistance rating up to that of the rest of the structure. Sewatek service penetrations come with firestops, which means no separate firestop installations are required. Remember to always check the fire-resistance rating of Sewatek penetrations as they vary based on such factors as the material and diameter of the linepipe.
