Wall Penetration Caulking

Service penetration seals are passive fire protection systems designed to maintain the fire resistance of building element or section - wall or floor - where services such as cables, cable trays, pipes or ventilation ducts pass through them. The vast number of different building materials and different service and the types of penetrations that can be required, leads to a wide variety of different solutions for sealing around these services penetrations. The result is that for most of these penetration sealing applications, several alternative solutions, with different systems and products can be used if the combination has been tested. One of the challenges with sealing around penetrations is that certain services e. For this type of application, expanding intumescent materials are usually a very effective solution.

Dividing a building into discrete fire compartments is by far one of the oldest forms of fire protection incorporated into buildings. By separating larger buildings into different fire resistant compartments, areas or cells, either to separate factories from warehouses, plant and equipment from common areas, to divide different levels of high rise buildings, or to separate one townhouse from another, we can effectively increase the life safety of the occupants of the building and limit the extent of the damage to the building and to the business after a serious fire. Effective fire compartment barriers require all openings to be correctly sealed to maintain their fire integrity. This includes larger opening for doors, windows and the like, but just as importantly all openings for services. These include fire stopping of penetrations for plumbing, electrical and mechanical service types. The Guide provides specific information relating to fire stopping, covering briefly the Legislative requirements encompassing the Building Code of Australia, the relevant Australian Standards for design, installation, and maintenance. It also introduces the concept of a fire stopping system and discusses some generic types of fire stopping materials.

The following information is intended to provide construction and code enforcement professionals with basic checkpoints to ensure the required fire resistance ratings are maintained when penetrations and linear joints breach walls and floors. This inspection guideline is not intended to be all encompassing or to be used as a design guide. It is for information and educational purposes only. Annular Space - The opening around a penetrating item. F Rating - The time period that the through-penetration firestop system limits the spread of fire through the penetration when tested in accordance with ASTM E or UL

The vents and pipes that penetrate exterior walls and the roof bring the power, water and gas lines into a house, but they can also bring in drafts, mold and wood rot. Ignoring these breaks in a building's thermal barrier threatens the durability of the house and the health of its occupants. Knowing where these penetrations are and how to seal them makes it possible to reduce utility bills, prevent drafts and stop the infiltration of moisture and all the problems that come with it. The "best practice" is simple, and often overlooked.
