Dense Packing Exterior Walls-Middletown, VA

Friday, April 20th, 2018 by Justin Dobson

Challenge

This Middletown, VA homeowner was complainging that their home was cold and drafty this winter. They called Comfenergy to set up a free comfort evaluation. Upon a full examination including a blower door test, thermal imagery, and other testing it was determined that the rear of the home had almost no insulation in the exterior walls.

Solution

The best course of action for this homeonwer was to dense pack the rear walls of the home. This was done by removing the exterior vinyl siding and drilling holes in the sheathing. Flexible tubing is installed into the stud cavities and TruSoft cellulose in then blown in and densely packed.

The homeonwer has reported that not only did the drafts lessen, but the road noise from behind the home was lowered too!!! A 2 for 1 solution!

This Middletown, VA homeowner was complaining of a cold and drafty home.

Here is a shot of the Comfenergy production crew member removing the vinyl siding on the rear of the home to access the sheathing.

A view of the rear of the home after the strips of vinyl siding have been removed.

This is what the holes look like after they have been used to dense pack the exterior walls.

Notice the holes are completely full and overflowing with TruSoft cellulose proving that the exterior wall cavity has been filled.

Sealing up the holes with a one part spray foam before putting the siding back on.
