Not much going on today so tonight we will report on how we do thermal transfer control on the Castle’s windows.
The window frame around the windows of the Castle is 3/4“ wide. That makes it convenient for 3/4“ thick polystyrene foam to be cut to fit and pressed in place. The 3/4“ foam is rated at R3 and can be cut to fit very tightly or just firmly. Over the las few years we have come to prefer the just firmly fit. The temperature control is very good. We use it for keeping out the summer sun and keeping in the winter heating. Here is a picture of the main window of the Castle with the foam in place.
We buy the foam at Lowes in packages of several pieces about 15“ wide by 48“ long sheets. This size is easy to handle even in the wind while cutting it to size to fit the windows. A regular sharp knife does the cutting very well.
We have several other spots in cabinets that have had the foam added against the outside wall and ceiling to add to our winter/summer thermal resistance.
Overall we have noticed the better temperature control in the Castle. And Yes it helps lower the heating or AC bill all year long. We started adding insulation way back in the late 70‘s on our first RV.
Keeping the inside more comfortable is important to the Teams when trying to have tooooo much fun.
