Fire-rated caulking

Waterproofing and protection!

Firestop caulking

Firestop joint caulking.

Firestop caulks play a very important role in protecting the building against fire, and these are their unique functions. Given their importance, the caulking of firestop joints should not be taken lightly and must be carried out according to the rules of the art and in accordance with the standards in force.

Firestop joint caulking for your health and safety

Without these suitable fire and smoke proof protections, the security of the building would not be guaranteed. Proper fire-rated joint caulking and smoke sealing of fire-rated walls, floors, and ceilings, as well as the penetration of objects through fire-rated walls, helps to extend the time to safely evacuate a building in the event of a fire. Our fire seal system is designed to prevent the spread of fire and the spread of smoke and toxic gases. Maintaining adequate fire and smoke barriers also helps reduce fire and smoke damage.

We have specialized in the installation of fire seals for over 20 years

Before laying the seal, our caulking experts prepare the surface:

* We carefully clean the area to be treated and the perimeter of the surfaces.

* We remove any trace of mortar, cement or other element that could alter the adhesion of the product.

Once the surface is well cleaned, we install a firestop wool before applying the caulking sealant to the firestop joints. We offer a professional and aesthetic service, our experts are qualified to ensure that the installation is done in a homogeneous, perfect and harmonious way. In addition, in the final phase an adhesion test to check the quality and resistance of the seal on the material.
