Blown in Fiberglass Insulation - Fiberglass Meets Cuisinart

  I was just cyber-browsing through the blog archives and realized I’ve written about regular ol’ fiberglass but never just about blown in fiberglass insulation. 10 years ago this might have been no big deal but the box stores have adopted blown in fiberglass in a huge way. One of my best friends is a […]


Blown In Fiberglass vs. Fiberglass Batts

Blown In Fiberglass vs. Fiberglass Batts

    I suppose it was only time before insulation manufacturers realized they could forego the expense of all that kraft paper binding the fiberglass batts. At first blush, it seems like blown in fiberglass and fiberglass batts ought to be very similar. I mean they’re both fiberglass, right? However, it’s like saying glass shards […]

Cape Cod Style House

    OK, I’m re-using the photos from last week’s post. Heck, it’s my house. Why not. I wrote last week about the difficulties with heating Capes. Cape Cod style houses are enormously popular throughout the country and particularly in their region of origin, New England. The style has been around for centuries but leapt […]


The Difficulties in Heating Cape Cod Style Houses

Cape Cod Style House

    One of the great ironies in construction (I bet you didn’t even know there was ironic construction) is that Cape Cod style houses perform pretty poorly on Cape Cod. The year-round sea breeze wash (wind wash even) right through the Cape building frame, making them chilly and uncomfortable in the winter months. How […]

Should I Insulate My Garage Ceiling or Garage Walls?

  This is what happens when you write a post with crazy enthusiasm. I ripped through this previous post and in my enthusiasm to tackle insulating finished rooms over the garage, I forgot to clearly state the garage ceiling vs. garage walls question. So let’s be a little less opaque: both approaches can work but […]


Post image for How Does Insulation Work (That’d Be Good Old Fashioned Science)?

  I talk with customers about insulation during every audit. We discuss different types of insulation, why XPS is more appropriate for basements than fiberglass (seriously, people) or why rockwool is safer in temperature sensitive situations. Understanding the material properties and how insulation retains heat is essential for picking the right insulation for the job […]


Should I Insulate My Basement Ceiling?

should I insulate my basement ceiling

  One of the most common questions I get on energy audits: Should I insulate my basement ceiling? The interior floors feel cold, the house is warm, the basement is cold, insulation slows heat loss so I should insulate my basement ceiling, right (customer looks at me for affirmation)? Actually it’s nowhere near that simple. […]

Fiberglass Insulation

  What is fiberglass insulation and why does it have that pink color? When was fiberglass insulation first used and what is fiberglass insulation used for today (besides insulating presumably)? What is Fiberglass Insulation – Your Boring Wiki-Style Answer Fiberglass is a man-made material used in construction for thermal insulation and sound proofing. It is […]


Does Fiberglass Insulation Work Well?

fiberglass insulation

  Why doesn’t fiberglass insulation work as well as other types of insulation? What is the best type of insulation for your home? How would you best insulate your home – and does fiberglass meet that requirement? Does fiberglass insulation save more money than other types of insulation? Before I became an energy auditor, when […]
