I am about to pull the trigger on having a 5.9kW system put on our home/office, but honestly PV systems are kind of outside of my realm of expertise (I mostly work within air sealing and insulation…Continue
"I think Sean is onto the answer. The blotchyness makes me think they may have used a spray can primer like "Killz" in a can to cover water damage or mold. If they shot it on there thick enough it could create a thermal difference.
"Steve, Chimney dampness is a much bigger problem in the UK than it is in the US. It is because of the weather difference and the chimney structural differences combined. But you are correct that you do not want to trap moisture inside of a chimney…"
"In existing homes I have not seen the outside air intakes executed very well. Most times they are without dampers. Worse yet, in prefab fireplace configurations they terminate inside chimney chases instead of outside. So they just end up being…"
"I think the number of chimney draft excluding products is a testimony to what a problem the fireplace can be with the efforts to make a home more efficient and also meet the demands of the homeowner.

A group where energy professionals can learn about all the different energy saving aspects of RCCs. I have worked with one particular RCC for 30 years. I have amassed alot of information I can share. Everyone knows, accepts and understands how RCCs work as a 'Cool Roof' coating. However, that seems to be where the knowledge on these products different energy saving applications abruptly stops.
