How to Beat the Anne Arundel County, Md Summer Heat

Summer home comfort in Anne Arundel County, MD

The heat from the hot attic radiates rapidly into the home if insulation is mis-aligned or missing.

Look to building science and having a proper assessment performed to help you make the right improvement choices for home comfort in the hot summer months.  A new HVAC system is likely not the right solution for a cooler home in summer.

Temperatures in the attics of Anne Arundel County, MD homes during summer months can go as high as 150-160 degrees.  It is a brutal place with stifling air and high amount of humidity.  When an attic is not properly vented, air sealed and insulated the stagnant hot air and pressure in the attic forces excess attic heat through the drywall and other bypasses into the house making summer days at home a drag.  

Consider this:

Anne Arundel County MD homeowners that have a minimum insulation level in the attic equal to R-19, reflective roof shingles and proper ventilation can experience up to two-thirds less solar heat gain than those with characteristics such as little to no insulation, dark roofing shingles and no attic ventilation. 

Summer home comfort remedies for Anne Arundel County, MD homeowners:

  • Proper baffle installation 
  • Proper insulation levels 
  • Proper air sealing 
  • Proper rim joist treatment
  • Proper crawl space treatment
  • Proper intake at soffit 

Comfort and even temperatures on all floors can happen on hot summer days!

Effective Insulation is Two Parts
Regardless of which material and application is used, insulation is not fully effective in Anne Arundel County home attics and other insulated areas unless it is properly installed and fully aligned with a contiguous air barrier. Insulation works because it incorporates air pockets that resist the flow of heat, or slows the conduction of heat. This resistance to heat flow is measured by the R-value of the material. 

Most insulation (with the exception of spray foam and rigid foam board) does not stop air flow.  The most cost effective insulation solutions for a house in Anne Arundel County Maryland requires a separate air barrier or "skin" to stop the flow of air. For the air barrier itself to be effective, it must be contiguous and continuous across the entire building envelope, with all holes and cracks fully sealed, and it must be perfectly aligned with the insulation. 

As a general rule, warm air moves towards cold air.  Insulation slows the movement of the heat way down when the thickness is at R-49.  Air sealing keeps humidity out of the home in the summer, particuarly in the basement areas.  Air sealing also acts as another line of defense against heat from the attic.
