What the heck is attic air-sealing? We get that question a lot. The striking thing about attic air-sealing, is that it’s probably the single most beneficial thing you can do to your house. Per dollar spent, air-sealing will result in the biggest energy savings. It will also improve comfort, by reducing the temperature discrepancies between floors and across rooms. By […]

Testing Accuvent Cathedral Baffles
Here’s a video we made of us testing accuvent cathedral baffles. Pretty fun day, but we’re probably not going totally viral with this one. Nevertheless, building geeks might find it interesting. Prior to the test, I really thought that the baffles would crumble. Not the first time I’ve been wrong. You may notice a little bit of cellulose seepage on […]

Put that in your energy modeling software and smoke it!
Here’s a photo I took a few months ago during an energy retrofit. Yup, that’s 110F supply air from the furnace being dumped into the unconditioned attic (for thermal purposes what we call “outdoors”). The most plausible explanation is that this was an attempt to fix a cold master bedroom a few feet away. To make matters worse, the duct […]

3D modelling an addition
The owner finds this room uncomfortably warm in the summer, uncomfortably cool in the winter, and generally uninspiring year round. It is an important room as it is open to the kitchen, the busiest place in their home. To get a real feel for the existing conditions, I import photos into Sketchup and create and ‘Existing Conditions’ model. Then I […]

Stuff We Like – Dryers
Here are two products related to dryer venting. 1. We’ve installed a couple of dryer boxes. The dryer box saves you from having your dryer duct turn into a kinked up nightmare. 2. The Heartland dryer vent closure is wicked ugly. But it does an excellent job of sealing against air leaks, not to mention gross critters. The good news […]

Some Guy Goes Green
This one’s a rant. Unfortunately for environmentally conscious builders, the rising publicity surrounding ‘green’ building has coincided with the collapse in building construction across the planet. Usually I don’t think that personal experience can really indicate a trend. Nevertheless, it’s hard to ignore the fact that 2 years ago, ‘Some-Guy Construction’ was throwing up (almost literally) speculative pseudo-home junk with […]

Air-flow Diagnostics for Cavemen
The Canadian Mortgage and Housing Corporation does some pretty fun stuff. Here’s an interesting test to measure airflow at registers and exhaust vents. Seems so obvious once you know the ‘secret’. For those who find the myriad of government-funded energy subsidies confusing, here’s a link to a state-by-state breakdown of the programs.

Well what about unicorns?
I’ll just give it to you straight. Dry rot is a myth. Excessive dryness doesn’t cause it’s own special kind of rot. While this might seem intuitive for the layperson, it’s a pervasive misconception among those working in the building industry. From Paul Fisette’s article on wood myths, ” Wood needs 4 things to decay: water, oxygen, food (wood) and […]

Building Codes Made Free and Easy
Last September the San Francisco Chronicle published this brief but fascinating article about Carl Malamud. Apparently Malamud had been putting building codes on his website, and allowing anyone to download them, entirely free of charge. At the time it seemed like an interesting story. However, I felt pretty certain of two things. First, that Malamud was probably some sort of […]

Energy Efficiency and Taxes
With the federal stimulus package there’s been a lot of talk about government money being used for energy improvements. A lot of builders (including Tay River) have been focused on energy efficiency for a long time. As a teenager, my first construction job was for an insulation contractor in eastern Ontario. We’d occasionally work on R-2000 homes, which were part […]
