Hoses

One of the most important tools, next to your brain, when installing a blown in application is the hose system. Most think they are nothing more than the conduit to get blown insulation from point “A” to point “B”. But in the dense pack systems they are a critical component.
Once the blowing machine chops up the bale of blowing wool, pieces of it. Chunks, flow into the hose. What we want is no chunks of fiberglass coming out the other end. This is where the hose makes itself so important.

Some how the chunks of fiberglass need to be broken down to individual fibers that helps us create the correct flow of product and the ultimately the correct density. That happens in the hose. How? You’ve noticed the hose is made with a series of rings, ribs. These features are what breaks down the chunks of glass into the loose fibers we need.

But this can only happen if we use the hoses correctly. How do we do that? First we have to have enough hose. For a great application we suggest between 200 and 300 feet. Why so long? Because, second, we want to see at least 100 feet of that hose wound up permanently. This allows the chunks of fiber to flow thru the hose, being forced to hit the sides and ribs breaking up the chunks in to usable loose fibers.

So by the time the product hits the end of the hose, it is loose enough to enter the empty cavity, flowing around anything that happens to be in the way, pipes, wires etc. giving the applicator more control and flexibility. This is why the lowly hose is so critical to the blown in application.
