Doug, the Ductwork Detective here,
It's Getting Hotter! Record high global temperatures in 2014, 2015, and 2016.
Did you know that the month of July 2016 was the 15th consecutive month of record global highs since humans began recording temperatures? July 2016 was the warmest July on record for the lower 48 contiguous U.S. states! We found this information published on the NOAA's (National Oceanic and Atmospheric Administration) website. The WMO (World Meteorological Organizaion) website tells us that global temperatures broke new record highs every month from January to July 2016 and that arctic sea ice melted earlier and faster!
It's more important than ever to seal air ducts tight and coat roofs white to reduce heat gain in homes, offices, apartments, stores and all building types. RCD's #6 Mastic and #15 Weather Barrier Coating are the best choice for improving indoor comfort.
