Spray Foam: Keeping The Roof Over Your Head


Spray Foaming Steel Trusses for Fertilizer Company

As spray foam continues to grow in popularity, home and business owners are finding new ways to reap the benefits of its strong insulation properties. Recently, Master Pack was contacted by a fertilization manufacturing company that needed to add a protective barrier to steel trusses of their factory ceiling. The main issue was bacteria from processed fertilizer caused the steel trusses to rust and deteriorate. Closed cell spray foam provided a viable solution because of its strong air/moisture barrier qualities.

What does this video show?

As you may have already noticed, this is not a typical spray foam application. The foam is not being applied directly to the ceiling. The following video depicts spray foam insulation material applied to steel trusses in a factory producing and processing fertilizer. This is a unique video in that the foam is applied to the trusses/steel Beams to prevent the advancement and production of bacteria etching into the steel.

Protecting the Steel with Closed Cell Foam

The bacteria have a tendency to migrate in the factory to the steel beams. After they have established a harvesting point, the steel begins to rust which causes structural failure in the factory. The advancement of rust is quite severe and thus requires a coating of foam to block the bacteria in their quest for migration. The spray foam material is unique for this application because it is non biodegradable. In addition, this closed cell foam has fire retardant qualities.

Foaming for the Solution

The Closed Cell structure of the foam will not allow moisture or air permeation to feed the bacteria thus removing any concern of rust and ceiling structure failure. When speaking further with the fertilization manufacturing company, Master Pack learned that other companies have used closed cell foam in this way to prevent bacteria from damaging the steel. Spray foam clearly has a large array of applications, some of which may have yet to be discovered. As always, please reach out to us if you have any questions regarding spray foam insulation.
