Fire block foam can save time, trouble and provide the kind of fire protection the modern contractor needs. In fact, these products perform more than one job and are extremely convenient to use. Let’s look a closer at this kind of foam and discover why choosing the right product is vital.
Why Use Special Foam for Fire Blocking?
You must seal certain spaces to keep fires from spreading and this is required in most municipalities. In fact, failure to properly install fire blocking foam can result in a claim on your professional liability insurance and could seriously damage your reputation as a contractor. This is why it is important to choose foam which meets or exceeds the building codes in your area.
A good foam product can fill both small and large spaces. Plus, orange colored foam is best to use because it simplifies the inspection process.
Where to Use Fire Block Foam
Fire blocking sealant should be used around all electrical outlets. This includes switch boxes and air ducts. In fact, any area of a building which allows passage from one level to another should be properly sealed.
Choosing the Right Foam
Some foam can emit fumes which may be irritating or harmful, so choose a product with no harmful emissions or odors. Look for products which are ICC-ES Certified. They should be rated for ASTM C1620 and have a high ASTM E84 rating (5 of 5). This ensures you are getting the best foam for fire blocking and sealing.
To save on costs, consider a high-yield foam product. This gives you much more sealant per container. In fact, quality high yield foams provide as much as 25 percent more sealer per container.
Installation
Even the best fire block foam will not perform properly if not installed right. First, choose the right application for the job. For example, some places are easier sealed with straw applicators (small hard to reach areas) while others should be installed with standard foam applicators.
Before installing, make sure the area is free of dust, dirt and any kind of debris. Wear the proper protective clothing and equipment for the job. The area should have sufficient ventilation also. Check with the instructions to confirm temperature limits on application.
You may need to use masking tape on areas near the foam application. If your installation will be exposed to UV rays, it should be painted. Finally, make sure to clean up afterward and trim excess fire block foam which has cured.
