Holliston LEED House

This is the story of a family who built the first LEED "green" house in Holliston, Massachusetts. We were trying to spend no more than it would take to build an ordinary house,and maybe even succeeded. The dust is still settling.

Sealed With A... Can?

In this picture, Tom is sealing the cracks between the panels with foam insulation. He drills an access hole, fills it, drills another, fills it, all the way along each seam. Anyone who has insulated knows that if you miss a spot, you've missed it all. So foot by foot, space by space, wall by wall and roof panels too, all the seams are sealed up tight.

XPS has a high R-value (5 R-value per inch of panel). This means a very well-insulated envelope that should heat and cool with minimum effort.
