Regardless of which material and application was used in houses built in Rockville, Maryland, insulation is not fully effective unless it is installed properly. Insulation in Rockville MD works because it incorporates air pockets that slows the conduction of heat. This resistance to heat flow is measured by the R-value of the material.  However, most insulation in a Rockville, MD home attic does not stop air flow.  Thus, for most insulation to be effective in a house in Rockville, a separate air barrier or skin is needed 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 and it must be perfectly aligned with the insulation. 

Comfort in both winter and summer is related to four factors in Rockville, Maryland:

1. Air temperature
2. Relative humidity
3. Radiant temperature
4. Air movement
For every cubic foot of air that enters a cubic foot leaves, taking the heating or cooling energy with it.  If air sealing is missing at the attic floor in a Rockville, MD house then it is likely to function less efficiently and uncomfortable.  For most insulation to be effective air sealing is needed to stop the flow of air. Most Rockville attics are insulated to between. R-10-30 (5-15") and there is no air sealing.  Increasing the R-value to 49 as recommended for the Rockville, MD area will improve comfort and efficiency.  Any attic access point to the attic such as a push up hatch should be treated by sealing and insulating. Recessed lights should be covered and sealed at the attic floor prior to adding insulation.  Baffles should be extended/added where necessary to maintain attic ventilation for the climate in Rockville, MD.
