Don’t Live in a Styrofoam Box: The Truth About Real Insulation

The structural lumber for the site, which was sufficiently sun-dried in advance, has arrived at the workshop.
The thickness of the studs is 184mm (2×8). Since the general standard is 2×4, these dimensions are double that.
Essentially, double the amount of fluffy “glass wool” insulation goes into the outer walls, just like a thick cotton duvet.

I don’t know if they are camping coolers or styrofoam fish boxes, but many recent new houses are covered in hard, petroleum-based “XX foam.”

What is important in a house is “heat retention.”
A fish-box house that gets chilled to the bone the moment you turn off the heater cannot be called high-performance.
By putting lots of glass wool in the walls, ceilings, and floors, the house stores plenty of warmth indoors.
It goes without saying, but while houses like fish boxes might have high performance numbers, soundproofing is terrible—you can hear voices from outside clearly, and voices from inside leak out too lol.

Measuring the wood’s moisture content.
Thanks to the lumber dealer’s time and effort, the result is an average of 8-9%. It’s a surprisingly low and stable figure.
Speaking of laws and standards, the Building Standards Act suggests 15% or less, and JAS certified lumber is considered acceptable at 20% or less. But from a pro’s perspective, wood still moves even at 15%, and at that moisture level, distortion inevitably occurs after construction—that is the reality.
Obviously, drying is crucial (emoie uses the same drying process for all buildings).
The 2×4 method uses smaller cross-sections compared to the thick pillars of traditional methods, structurally making it easier to dry evenly to the core. Traditional thick pillars often don’t dry out in the center, causing “warping” later, but sufficiently dried 2×4 lumber offers a different level of peace of mind after building.

Sigh… must be nice… Abashiri City 17,000 yen… Kitami 4,000 yen… Even with the same shipping cost via Yu-Pack, the contents are more than four times different…

Kitami City officials too, having wages frozen for 3 years in this era of hyper-inflation… motivation must be… plummeting.
There is one serious, non-poetic alchemy for a revival…

But that’s for another time ♪

I finished watching “Culinary Class Wars” (White and Black Spoon)—it was so fun!—and now I’m watching this.

Kim Seon-ho… is so cool.
It’s his first drama in 5 years since “Hometown Cha-Cha-Cha”.

Episode 1 is set in Kamakura, and I recommend watching at least just the first episode!
Even so, I was surprised by Sota Fukushi’s big selection for a global debut.
He’s 183cm tall… same as Kim Seon-ho.
If you’re not a tall handsome guy, you can’t make it in K-dramas, huh…………………….
