I’ve come to learn that people in the construction industry have very strong opinions about insulation. There are basically two categories, people that love spray foam insulation and people that hate it. Adam is firmly in category A, while our builder is firmly in category B. It seems that builders either exclusively use it or won’t touch the stuff.
Reasons people hate spray foam –
- It has been known to have issues with rot and mold
- Price (it’s about twice the cost of regular batt insulation)
Reason people love it –
- It expands to fill every nook and cranny making for a very efficient house
- Results in lower energy bills
Personally, if the decision was mine, I probably would have gone with regular batt insulation. I want the most energy-efficient house possible, but when people throw around the words “rot” and “mold” it scares me a little. But Adam has a friend in the spray foam insulation business, and he (and plenty of other people) assured us that the problems spray foam had with mold and rot are in the past and have been worked out many years ago.
And so, we foamed.
It’s a fairly quick and straight forward process. First they covered all the windows, fireplace, and everything that you don’t want to get overspray on with plastic, then they start spraying.
Here is a 30 second clip of how it works, it’s actually pretty cool. It goes on as a liquid and immediately expands to fill the space (we used open cell spray foam).
Both my boys thought this was the coolest thing ever…and I think it’s great that they are really interested in the process and are learning how a house goes together.
It’s kinda funny actually, Elijah is in kindergarten and his school work will be something like a worksheet that says “write three words that start with the letter F” and he will put “frog, framing. foundation” (or at least try to spell those words). We kinda have a one track mind over here.
So after the foam is in the crew comes back and cuts off any extra foam that stick out past the studs.
They did a great job, and even did things like seal off at the joints between studs in a corner. That’s some attention to detail right there.
We had everything foamed, the ceilings, walls, attic…everything.
It’s standard protocol to only insulate interior bathroom and plumbing walls, and that’s exactly what they did (with batts, because you can’t foam interior walls – there’s nothing for it to stick to.)
We also paid a little bit extra to have the ceiling insulted below the attic space. That way the noise will be kept down if/when we turn that into livable space. Here is the boys bathroom with all three types of insulation.
(That room is definitely the cave of the house with only one small window.)
Here is the attic in all it’s foamed glory…according to our builder we will be able to store chocolate in here. (aka – it won’t turn into a furnace in the blistering Texas heat.) I guess that means the attic is where I’ll do all my hiding from the kids.
They also foamed the stink out of any unused eaves in the house, covering the studs and everything.
Looking in there reminds me of living in upstate New York for six years. I can’t say I miss the weather.
Next week the sheetrock starts going in, which feels like a big turning point. Can’t wait to see this baby with some walls!
