Drapes - first steps

We measured, marked, and 'membered everything for the thermal drapes in Coffee Jones' studio, which is a) the coldest place in the house, and 2) is out of sight, and so is an ideal test case. Coffee bought 12 yards of the insulating material, and a few other items, such as plastic rings, that we need for making the drapes. So far, we're in for about $30 of startup costs, and $640 in materials for the first window. That's a marginal cost of about $5.50/square foot of window. At a savings of 25 BTUs/square foot/hour (with a 40F temperature differential and $4.50/gallon heating fuel) that's a payback of 6844 hours, or 285 days. That sounds like about 3 years or so, considering that we use the heat for 7 months out of the year, and the temperature differential does not average 40 degrees.

We paid $6730 for heating oil this past season. We'll see how we do next season. Just as it was when I was growing up in New Hampshire chopping wood, there are two seasons: winter and getting ready for winter.
