Specifications & installation of penetration seals

• Establish the type, size and number(s) of the service(s) passing through the wall or floor and ensure the proposed sealing system is    fully tested and approved for sealing around such services.
• Establish the dimension of the opening and ensure the proposed sealing system is fully approved for such dimensions.
• Determine the construction materials used for the wall or floor, and the size of the penetration and ensure the proposed sealing    system is fully tested and approved for use in such substrates.
• Check for any possible differential movement of the structural elements within the building.
• Determine the likely maximum movement of the service pipes and/or other services.
• Check if the seal has a loadbearing requirement.
• Determine a system, which is compatible to both the element (wall/floor) and the penetration sealing system.
• Establish the environmental working conditions within the building (in areas of high humidity certain materials could break down).

The above is by no means definitive but provides an indication of some of the questions which need to be resolved prior to the preparation of any specification and certainly well before any installation.

This aids the specifier in selecting correct materials and, more importantly,the best system configuration possible, ensuring that the building is adequately sealed against the spread of potentially fatal fire or smoke through penetrations.
