It’s going to be a good winter at our house. And by “winter” of course I mean the next six months because, really, winter lasts that long in Vermont.
To be sure, we recently tackled the following tasks: changed the air filter in the furnace so it would run more efficiently, installed a new thermostat that now works with our wall heater on the second floor, scheduled a chimney cleaning so we can use the wood stove as a heat source, chopped wood that has been drying for a year for said wood stove, and made a HUGE ADDITION to the insulation in our attic. All of which is to say we should be nice and cozy this winter.
What I’m really itching to tell you about is the insulation. Ba-dum Ching. Because really, who doesn’t get all warm and fuzzy talking about insulation?

Okay, enough with the puns. Back to serious business.
Installing insulation has been on the to do list since we moved in. We really should have done it before our first winter here – it undoubtedly would have saved on the heating bills – but I’ll be the first to admit it was a little daunting to think about at the time. Daunting because I really wanted to know that we would make the right decision about what type of insulation to install and how to install it, and at the time I was convinced we’d need a qualified expert to help us with the task. Daunting because we were talking about a potential health hazard: crawling around in what I pictured to be a mouse-poop-filled, dirty, scary attic playing with the existing fiberglass insulation. Well, okay, not quite playing with it but throwing it around a little.
For example, here’s the mess we were working with. No wonder I was daunted.

How did we know we needed more insulation up there, and just how much did we need? For one thing, last winter was cold. But again, this is Vermont so that wasn’t much of a shock.For the answer, bear with me for a little jargon for a minute.
Building codes in Vermont stipulate an insulative value of R60 in attics. We figure before we moved in there was maybe R38 at most. In some places there was one layer of insulation, with an R value of 19 (at best). In some places there were two layers bunched up together or compressed under plywood boards, (while it may seem counterintuitive, compressing reduces their effectiveness). In many places there was one layer or even nothing, like on the attic hatch itself. Um, what’s the R value of nothing?
So at best we had R38 in the places where there were two neat layers of the pink stuff. But along the back side of the house there was an entire ~2′ gap where there was no insulation at all. No wonder the office was freezing cold last year and our roommate had to use a space heater!
Anyone who knows about this stuff will tell you that houses have to “breathe”, sort of like what’s going on in the image below. But I think there was too much breathing going on up there. Our attic was hyperventilating.

The more we learned about insulation the more we realized it was a DIY project that we could tackle, but we had some decisions to make first.
Deciding on the type of insulation was not easy. There are so many options, each with their own set of environmental and health implications. I wanted to get some kind of recycled/eco/healthy/green stuff like cellulose. Or maybe insulation made from hemp or sheep’s wool. Or we could go really wild and hippie and get insulation from recycled blue jeans.
Which, for example looks like this:


Another choice to make was whether to use rolls (aka batts) of insulation or blown-in insulation, which can do a great job of filling every nook and cranny (why am I tempted to stop for a photo of English muffins?). While it is a bit involved to install blow-in insulation, I bet it’s fun to play weatherman, sending a snowstorm down on the unsuspecting attic floor like this guy.

I say involved because to install blown-in insulation, we’d have to rent a machine that sits outside (on our back deck, probably) with someone feeding insulation into it (me, probably), and run a tube up through the bathroom window into the attic hatch where someone directs where the insulation blows (Mark, probably). I can’t imagine how we would possibly communicate with each other while doing this process, and we couldn’t really plan when to do it in advance as it would be very weather dependent. Plus, we wouldn’t be nearly as comfortable as the guy in the picture above as you can’t stand up straight in our attic.
So, despite the fun insulation options like keeping warm with last year’s Levi’s or creating an avalanche of insulation with a big machine, we opted for just rolling out more fiberglass insulation on top of what we already had.
A few compelling reasons: 1) the best bang for the buck (R value per dollar) 2) easy-ish installation. No need to rent a piece of equipment, and not weather-dependent 3) readily available at Lowe’s 4) we had to deal with the existing fiberglass anyway so we knew we’d be wearing respirators and getting gross no matter what 5) even though it isn’t as eco-friendly a product as recycled blue jeans for instance, I think we get some eco points simply for installing more insulation period. Don’t the ends justify the means in this instance?
In our case it means we went for the standard (formaldehyde-free!) fiberglass insulation at Lowe’s for $10 a roll. Each roll covers 25 feet with 15″ of R30 insulative value. It took two trips with Jenny-the-Truck to pick up everything we needed, and then we were on a roll (sorry, I’ll stop now).

For the past few weeks these rolls have been living in various locations around our house. I’m sure the roomies are happy we’ve finally decided to do this project and get them out of the living room.

Now there’s space in the living room for more important things. Like cat baths.

We didn’t get any great shots of the process of installing it. It’s unadvisable to bring a relatively expensive camera into a cramped attic with fiberglass dust floating everywhere. But here are a few photos that show some of the chaos of this process.
Here you can see the mess of existing insulation behind Mark, some of which was moved out of the way when contractors did projects like adding recessed lights to the bathroom. Also take note of the styrofoam soffit covers. Our goal was to fill in all insulation gaps up to, but not covering, the top of those covers. This would still allow the house to breathe. Oh and you see the pvc tubing (sink and toilet vents)? They’re a real pain to work around fyi.

Here’s a blurry me, holding up a piece of insulation that I’m about to shove in a crevice somewhere. Or maybe I was about to start a pillow fight with Mark? Tempting.

Once we were done rearranging and organizing the existing insulation, we rolled out the new batts on top, which added a beautiful 15″ blanket on top of everything.

Since we don’t have any great photos I stole one from someone else online. What you are about to see is not actually our attic, though it looks very much like what we were dealing with: Existing insulation between the joists with new rolls on top in the opposite direction. Only in our attic we weren’t smart enough to have a plank of wood to walk on top of. Instead we had to be sure to walk only on joists (or risk popping a leg out through the ceiling below).

Thankfully I have no injuries to report, but I may seriously need to burn the clothes I worked in. Any tips for getting fiberglass out work clothes?
I’m also happy to report that I already notice a temperature difference in the office. Come on, Vermont, bring on the winter. We’re ready!
