Call Before you install

Call Before You Install

When it comes to choosing the correct firestopping product, to resume the integrity of a fire-rated assembly, remember to call before you install.

With years of experience in the sealant, adhesive, and firestopping industries under our belt, we have observed our fair share of costly errors made with firestopping products. Particularly with misapplication and improper product selection.

Some easily preventable mistakes we commonly see are:

  • Improper installation of our Fire Caulk-136 (FC-136) and our FlameTech FB Fireblocking foam (DP44242). The ASTM-E136 spec and fireblocking foam are for non-rated single-family penetrations.
  • Incorrect installation of bond breaker tape; bond breaker tape should be installed behind our Firestop-814+ when indicated, as it serves to buffer the joint and prevent three-point adhesion.
  • Using backer rod in place of mineral wood or not using backing tape material at all.

No one wants to have a job delayed due to a firestopping error, especially with the added stress and costs that come with it. As a rule of thumb, “if you have any questions at all, call before you install.”.

Preplanning your work with firestopping procedures in mind can help make the installation process easier and more efficient. Preplanning enables you to identify and address any concerns or issues that may arise earlier on. It also allows you to reach out to the product manufacturer, the AHJ (authority having jurisdiction), and other relevant parties for any additional information or clarity you may need.

When installing, make sure you follow the UL systems diagram, the product’s technical datasheet, and the directions on the product’s packaging. Neglecting to do so can result in a failed inspection or, even worse, a complete firestop system failure.
