What about using this system on an existing structure?

If there is an empty cavity, the BIC’s system can typically fill it. Take for instance an existing, older home with no insulation in the exterior wall cavities. It might be a little more complicated, but we can fill those cavities with just a little extra effort.

There are typically 4 ways to do this:

  1. Remove the siding at certain intervals, example near the bottom plate, near the top plate and 1 or 2 places between. Then holes are drilled thru any existing sheathing and BIC’s is then blown into the cavity to the correct densities. After the blowing process is complete the siding is replaced.
  2. Holes can be drilled on the interior side of the walls as well if there is a brick/stone veneer on the outside of the house. Typically, again, holes are cut into the wall cavities near the top and bottom plates (removing the base trim and possibly the crown molding at the top of the walls) allowing the installer to blow “up” and “down” from those holes till the cavity is full (sometimes it does require holes to be drilled in the center of the wall cavity if there is fire blocking in place. Then the best way to hide the majority of the holes is to replace the base board with a larger piece than was there to begin with. Then and the top plate area replace the existing crown molding or install new crown molding to hide the holes cut into the plaster or drywall.
  3. If the exterior is brick or rock, and you don’t want to cut into the wall cavities from the inside, an installer can, with extra effort, install thru the top plates through the attic space. This is the most difficult because we only have one place to insert the BIC’s system into the cavity. It will be hard to guarantee the product will make it to the bottom of the wall, especially if there is a window or fire blocking installed in that area.
  4. And finally, the last way to install BIC’s is by a total gut remodel. All of the plaster, or drywall has been removed down to the stud. We can then come in and install the system as if it were a new house. Fabric can be installed after all of the interior wall renovations are done and blow BIC’s behind the fabric.

If there’s a cavity and a will to have the most efficient, affordable system installed, there is a way!
