Weatherization Nation 5: Leak-Free Windows

Welcome to ProTradeCraft’s Weatherization Nation. A show about building smart from the start.

Last week we covered the walls with Tykek, a Weather Resistive Barrier (#WRB). We also learned how to upgrade it to an air barrier and cleared up a common misconception that we at Protradecraft see on our many travels around the continent:
Tyvek is a #WeatherBarrier, and it can be an #AirBarrier, but Tyvek is not a #VaporBarrier.

This week, we’re going to cut a hole in that air and weather barrier and install a leak-free window.

After eight days and nearly 600 linear feet of crown molding—some of it curved—DFW Crown Molding is ready to spray some paint on their work.

And rather than destroy everything in the house, they take the time to set up a temporary spray booth.

Rule # 1: Never Underestimate OverSpray

Engineering School: Concrete, Rebar, Tensile Strength, and Compression | ProTradeCraft

Concrete has very high compressive strength. Tensile-y, though, it is kind of a weenie. This is why we layer a grid of rebar into its guts.

Because compression does not happen in a vacuum. Well, yes, it does, but it does not happen in the absence of other forces...

How steel reinforcement makes concrete stringer: by giving it tensile strength. And how to boost tensile strength with prestressing or post-tensioning

Weatherization Nation 3: A Warm and Dry Crawlspace

Welcome to ProTradeCraft’s Weatherization Nation. A show about building smart from the start.

Last week we tore down an addition on the back, which left four large holes in the house. This week, we’re going to fill that hole with a warm and dry crawlspace.

First, they’ll waterproof and next they’ll insulate the walls with Thermax foam insulation.

Weatherization Nation episode 4: The WRB Is A BFD

The Tyvek weather-resistive barrier can be a water barrier and an air barrier, but it is NOT a vapor barrier. Even if it says that on the blueprints.

The show features Ray Williams, of Mark IV Builders and Terrence Donahue, a Tyvek Construction Specialist. We cover, what it is, why it matters, and how to install it right.

Extreme Cold-Climate Wall Hacks | ProTradeCraft

This video was produced by #Alaska's
Cold Climate Housing Research Center. Scientists who do research on the best way to build in particular climates make everyone's job easier, and everyone's house better.

I first met the folks from CCHRC at #buildingscience Summer camp (#bscamp) about a dozen years ago. Not only were they the most fun to party with, but they had some of the most interesting stories of building failures and solutions.

Oh yeah, and they used to bring a LOT of halibut to the evening cookout.

We can make do without the halibut, and we can teach the Minnesotans to be better partiers, but we cannot replace the research that the Alaska scientists do for all of the native villages dotting Alaska. And for the cities, there, too. We can't replace it because the rest of us do not live, work, or do science in that climate.

Did I mention that their budget was just cut to nothing? It was.

#Science is important.

Installing An Interior Air Barrier Membrane: Sealing Pipes and Wires (3 of 3) | ProTradeCraft

Last time the guys were grooving on a beat and stapling an air barrier. They also taped the sheets tightly.

Now, Ben’s going to cut holes in them just to prove he can seal them tight using two methods.

The first method involves using stretchy tape with split-release paper on the back. The other way to do it is to bed the ceiling sheet into the sealant. This means using an airtight work box with a flange built into the perimeter.

Installing An Interior Air Barrier Membrane: Sealing Walls to Floors (2 of 3) | ProTradeCraft

Ben and Rick have already stapled, taped, and squeegeed their way to an airtight ceiling and now it is time to turn to the walls.
They use a blower door and Infrared camera to find any obvious air leaks before installing insulation into the wall cavities.

Covering the walls with the air and vapor retarder membrane is not the tricky part. Sealing the membrane to the house is the tricky part. The top is taped, just like the ceiling.

Installing An Interior Air Barrier Membrane: Sealing the Ceiling (1 of 3) | ProTradeCraft

Interior membranes can be part of a high-performance wall assembly as a vapor retarder or as part of an air barrier system.
For them to work, though, they must be installed carefully.

The first step of installation is carrying the roll into the room, and rolling it out.

Dos and Don'ts for Propane Heater Safety During Winter Construction | ProTradeCraft

In most parts of the country, heating becomes a major issue for new construction projects in the winter and portable heaters fueled by propane are generally the most viable solution.

However, there are obvious safety concerns when using large, high-BTU, portable heaters—there is potential for harm to the structure you're building and the people who are building it if the heaters are not properly used.

When temperatures drop, propane heaters show up on jobsites. That's when fire danger creeps up ...

Surgical Remodeling: Remove Drywall Fast, Clean, and in One-Piece | ProTradeCraft

When it comes time to remove drywall during a remodel, you could bang holes in it with a sledgehammer (or your feet, like they do on TV) and then tug and tug at endless little pieces.
And then remove the tiny pieces surrounding the screw and nail heads, and then remove all of the screw and nail heads.
And then clean up the clouds of dust and mounds of crumbly drywall.

Or, you could remove the screws and nails first and remove the sheets whole, with no dust or mess. The choice is yours, but in case you're interested in doing it the latter way, here's master carpenter Matt Jackson to show you how.

Magnets are better than sledgehammers

Pneumatic Tools & Nailers continue their march toward cordless convenience, but don’t count out air power yet. There’s still plenty of innovation making the tools better and cordless is still short in the power department on some of these products.

The wall is framed with pressure treated plywood and flashed at the bottom.

To ensure long-term durability of the wall, we're using a rainscreen drainage mesh behind the siding. This allows the siding to dry evenly on both sides while allowing any water that sneaks in to drain out.

Flashing under a door and along the bottom of a basement wall that used to have an overhead door...

With the wall framed, the door hung, and the coffee hot, we are ready to flash the base of this wall against rain, capillarity, and splash back.

The first thing we will do is run a bead of high-quality sealant suitable for masonry and wood.
It will provide a backup layer of protection behind the flashing at the wall intersection and provide a bed for the flashing that will tuck under the door threshold.

The flashing will be installed in three pieces. The first piece slips under the threshold.

An additional short bead of sealant keeps sideways water from sneaking under the end pieces.

The top flange is sealed with flashing tape, and that pretty much wraps up the process.

From Pro Tool Reviews, the Pro Tool Innovation Awards for Safety and Workwear.

"Workwear and Safety is one of the judging team’s favorite categories every year. Many of the products that find their way to the winner’s circle have lifestyle applications even after the whistle blows to end the day on the job site. At the same time, it’s a serious category—being properly equipped is critical to getting the job done effectively and safely."

Water-Tight Crickets: Roll Roof Membrane for Tile Roofing

When installing a tile roof, it is important to understand that tile roofing is not waterproof. The underlayment layer under the roofing is the waterproofing layer.

This is NOT like asphalt shingles. The tile protects the waterproofing from UV degradation and impact from falling objects, so the roof must be watertight before tile roofing goes down.

  The underlayment is the water-control layer; valleys, crickets, and chimneys are the most vulnerable spots    When installing a tile roof, it is impo

In this episode, we fill up the rest of the roof and talk about workflow.

First, it makes sense to work off the pile of sheathing wherever the truck puts it, so make sure the truck puts it where you want it: somewhere you can cut sheets and pass them up so that carpenters can put it on the line and nail it.

Thank you for the recent posts about moldings, carpenters often get these wrong. Once you know how it goes, seeing the molding mixed up and sometimes in reverse order is, well, an unhappy sight.
