I have a pet peeve — and it’s not a tiny creature that sits around chewing with its mouth open. This time of year, it gets very hot around here, accompanied by high humidity. It hit 32°C (89.6°F) here yesterday, with a humidex of 38°C (100.4°F). That’s pretty hot no matter where you’re from, but around here our summers are short enough that we don’t truly get a chance to adjust to the heat. And yet, on days where the Weather Network is broadcasting heat warnings, I know people who sit in their air-conditioned homes and complain about the heat — despite the fact that they are sitting in a sun-bathed room. Put up some curtains already! You will be more comfortable, your energy bill won’t be so high, and you’re putting less strain on the environment. As a side bonus, in the winter those same curtains will once again help keep your energy costs down as they will help reduce drafts.

Now, I’m not talking about people who have legitimate financial, physical, or mental issues that preclude them putting up curtains. However, in my experience, the people who are in the direst financial straights are also the people who, out of necessity, will cut their utility bills any way they can — air conditioning is a luxury, after all. To beat the heat, many people will hang sheets or blankets over their windows with tacks. Sometimes people build improvised shutters out of flattened cardboard boxes. These may not be the prettiest solutions, but they are effective. Or, if a little money can be budgeted, it’s possible to shop around until the perfect curtains are found on clearance at 90% off. Learning to sew homemade curtains is also an option, not that much sewing has been necessary since the invention of iron-on hemming strips and curtain rings with clips.

No, what I’m talking about is people who should know better, and who have no impediments to putting up proper curtains, but choose not to and then whine that their summer cooling bill is so high.

As I mentioned, yesterday was one of the first scorchers of the year here, and of course that’s when my A/C broke down. We managed to keep our house at an acceptable temperature by opening up the windows at night and in the early morning, then closing both our windows and our curtains up tight for the heat of the day. By sunset, the house had warmed up somewhat, but we were only on the verge of “uncomfortable” — whereas outside it was “too hot to freaking move”. I credit that partially due to the fact that we have decent insulation in the walls (just standard, relatively-modern stuff to protect us from Canadian winters), and our curtains on the sunniest windows of the house being lined with blackout fabric.

My kitchen table with the curtains closed, after adding blackout lining.

To illustrate this, I took photos of my kitchen with plain curtains open, plain curtains closed, and curtains closed with blackout lining added. All photos were taken within a ten-minute span, and the curtains were all white Merete curtains by IKEA — which I love as they open/close easily and are opaque enough for privacy’s sake. The lining used in the bottom picture was heavyweight stuff purchased at Fabricland some years ago. I didn’t change the exposure on my camera so that it’s possible to compare the difference between the light let in by the lined and unlined curtains.

Curtains lined with blackout fabric (or with an opaque coating on the back of the main fabric) have become really affordable over the last ten years or so, as has the heavy-duty drapery hardware that it takes to support thicker curtains. It’s even possible to sew an old curtain to the back of a new one to maximize light blockage and prevent the fabric from fading. Or there’s always the sheet/blanket/cardboard options. If you don’t like “living in a cave”, as some have complained to me about dark rooms, you can only open the curtains in the room you’re currently in, kind of like a reverse-Nicole-Kidman in The Others. So to me, if you choose not to put up or close curtains, it seems an act of artificial helplessness to bemoan how hot it is and how high your home cooling costs have become, or that your brand new air conditioner isn’t performing nearly as well as promised. Wouldn’t it be better to take a stab at mitigating the problem rather than complaining?
