How to Beat the Baltimore, Md Summer Heat

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

 

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

Temperatures in the attics of Baltimore 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 and slowly, steadily and surely into the house.  

Consider this:

Baltimore 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 remedies for Baltimore, Maryland homeowners looking for attic insulation:

  • Proper ventilation intake 
  • Proper baffle installation 
  • Proper Baltimore attic insulation levels 
  • Proper air sealing 
  • Proper rim joist treatment
  • Proper crawl space treatment
     


Healthy Baltimore, MD Attic Insulation Vs. Unhealthy Baltimore, MD Attic Insulation

Effective Baltimore Attic Insulation is Two Parts

Regardless of which material and application is used, insulation is not fully effective in Baltimore 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 Baltimore attic 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 Baltimore 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. 

 

You need both parts of the jacket to make it work the best.  The same goes for the attic insulation around a Baltimore house.
