Foam Insulation for Cape Cod Home - Author's Note: See below for corrections to this segment
A Listener Thanks Tim for his Advice
On January 4, 2006 I received a very polite email from Peter Boyce, a Senior Consultant with Harbinger in Toronto, ON Canada.
He corrected a mistake I made during this broadcast and also made a few other comments. I do *not* agree with his points about energy savings paybacks. As I have said in other columns, you do *not* save money until such time as the savings on fuel have surpassed the extra money you spent on the upgrade.
His calculations may only do what he says when you get up close to the 50% projected savings. Not all homeowners see that type of savings. As they say in the car industry: Your mileage may vary.

- Icynene is open-celled spray foam insulation (not closed cell). During the segment Icynene was referred to as a closed-cell spray foam insulation. In fact, it is an open celled, light-density spray foam which contributes to its unique insulating properties: expands quickly to fill every nook and cranny; adheres to and moves with surrounding materials even as they settle/expand/contract to maintain air-sealing properties; the open-celled structure is hydrophobic (resists moisture), yet is semi-vapor permeable (allows any built-up moisture to diffuse out, so a building can breathe).
- Increasing R-values may deliver minimal and diminishing returns. According to Fourier
