Attic Insulation Photo Album: Brambleton VA attic insulation upgrade

This Brambleton VA attic had insulation that was porous and delivering an inefective amount of coverage to keep the home hot enough in the winter and cool enough in the summer.  Our sales professional Matt performed a full inspection of the home and determined that the attic was also lacking a quality air seal to keep from having conditioned air made by the HVAC system from escaping the home.  The homeowners complained that the room over the garage was also a pain point as far as year round comfort was concerned.  Matt identified several solutions for improving the existing comfort issues.   First, the existing insulation was removed and disposed of.  Once cleared, the attic surface was air sealed with ZypFoam at each space where there was a gap that would allow air to pass through.  This included HVAC vents, drywall seams, light fixtures and electrical boxes.  Can light covers were used to seal up all of the lighting and create a way to trap air from escaping the rooms below.   Next, the HVAC ducts were sealed with spray foam at all of the joints.  This helped to create a more air tight seal for the duct system and helped to prevent conditioned air from being allowed to escape where the ducts had any turns or connections.   After the ZypFoam air sealing and spray foam duct encapsulation was completed, the attic was filled with TruSoft cellulose blown insulation.  This material has a higher density than the original insulation and provides a higher R value.   Finally, the space between the garage ceiling and floor of the room above was dense packed with insualtion.  This will help to keep the unconditioned temperature of the garage from making the room above too hot or too cold.
