Building Resilience (12): Decking that Digs into the Landscape

Blurring the indoor/outdoor connection with a deck that runs into the ground, and a sunroom that looks like a porch

Building Resilience (8): All That Glass

First-time installing stackable sliders, a bifold window, and triple-glazed casement windows that are fastened through the frames: OA makes the mistakes, so you don't have to!

At long last, some clarification of this construction conundrum. @michaelanschel illustrates a common contractor conundrum.
Hint: its a soft "o" — like OBTUSE.

@BenjaminObdyke and @oabuilds, thanks for playing along!

Wind Resistance

a new episode of 7 Minutes of BS (Wind-Resistant Construction) just dropped on Apple, Google, and SoundCloud. It'll show up on Protradecraft in a couple of weeks, where you can READ THE TRANSCRIPT.

In the meantime, listen your guts out!

This episodes guest is Dr. Anne Cope, Ph.D., P.E.

Guest: Dr. Anne Cope, Ph.D., P.E., Chief Engineer of the Insurance Institute for Business & Home Safety explains why calling it hurricane resistance puts so many people at risk.

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

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.

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.

Furring and foam on the INSIDE for better walls in really cold places.

Making tiny boxes from skinny wood using a sweet adjustable box-joint jig is a good topic to watch over coffee on a Saturday morning.

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.

Stretchy gasket tape, flanged workboxes, and sealant can solve a HOLE lotta air leaks

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.

Two types of tapes for two air sealing applications

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.

I'm adding rooms to the inside of a pre built building. None will be bearing walls. They are motel/airbnb rooms so my main focus is to stop noise between each room. would the 2 foot centre concept of 2X4's work? Or should it by 2X6's
I subscribe to this channel on YouTube ProTradeCraft, it has everything you need to know about building or fixing things at your home or business! Try it it has a huge wealth of knowledge shared by some really good pros!
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.
want to show you Chebere for your van
