Home Performance with ENERGY STAR

Bee’s Building Technologies received training  insulating a home located in Stevens Point WI. .  The
purpose was to provide mentoring/training on air sealing and dense packing.  The owner, Barbara
North, was also on site and helped with the training.  The project consisted of locating and air sealing
all electrical penetrations in an attic floor.  We also air sealed wall plates, a stairway ceiling, an
abandoned chimney, a gable vent opening, and other miscellaneous openings.  We also blew cellulose
into two open joist attic areas and dense packed several small ceiling cavities.  In addition, we netted
rafter spaces and began the process of dense packing those spaces with cellulose.  The following
photos document some of the areas we addressed.  
Insulating a small attic with an opening
too small to fit into.  He was able to reach
all areas of this attic from this vantage point.
Feeding a hungry hopper.
Abandoned chimney sealed with fiberglass
and two-part spray foam.
Temporary dam installed to allow
completion of attic insulation.  An
insulated and weather- stripped door will
eventually be installed.
Dense packing a small triangular shaped
ceiling cavity over a hallway.

Foaming (low expansion – single
component gun foam) rough opening of
door to walk-in attic
Rigid foam board installed over dense
packed ceiling space and wall adjacent to
conditioned space.  Note taped seam.
The following Monday & Tuesday (July 2 & 3, 2007), work was completed on this project.  The per-
air infiltration rate was measured at 2,900 CFM50.  Following the air sealing/dense packing efforts,
the post test revealed the CFM50 rate to be 1,610.  That represents a reduction of 1,290 CFM50 (44%).
