warmer by the day...

Not the weather.

Nope.

Our house.

Startling discovery- we had no insulation in the roof.
None.  Nada.  Zip.

Our ceilings are plywood-weight wood panels.  They are slotted together in a very groovy (haha!) puzzle kind of way.

Above the ceiling is a whole grid system of beams and trusses and supports.  Quite reassuringly sturdy and beautifully made from real trees with all the undulations of real-tree wood.

And the main beam in the house has some beautiful brush-drawn calligraphy written the length of it that K assures me is some kind of blessing and not 'Property of the railway.  Fine for removal, ¥500,000' or somesuch.

But between these beautiful beams and the plywood thickness underlayer on the rooving tiles?  Nothing.

A whole lot of air and some dust (not near as much dust as the money shot on gekiteki before and after and as I have never vacuumed up there I'm now suspicious about those walls of dust they always show...) 

Air, dust and sunlight.

Yup.  There are little gaps and crannies in the roof that are open to the elements.  This is apparently so the house can breathe.  Pah.  When it getts too cold I can't breathe so the house can just deal I reckon!

And so this morning K and I spent our time in the roof space putting down glass fibre bats with a R rating of 2.  Yup, I now speak in R ratings.  But not very well.  K was trying in vain to explain to me why we couldn't get a super-duper R rating of 4 (most scales only go to 3.5) by just doubling up our R2 rated insulation batts.  Makes sense to me- 2+2=4!  I was getting as bamboozled as when he tried to explain that UV ratings on sunscreen are not a matter of simple arithmetic either and gave up.  Oh well, even one layer is still a whole heap better than plywood, dust, air and sunshine, right???

It was, perhaps unsurprisingly, very difficult to take pictures inside the roof crawl space but I had to try so:

You can almost see the curve on the main beam there.

Pink batts going in:

It's getting warmer!  I'm getting excited!  We're gonna be cosy!

I can never understand why Japanese houses have no insulation.... perhaps you could invite your neighbours in one day when the house has really warmed up to show them what a difference they make. And then politely lead them into your spare room where you happen to have a huge supply of pink bats that you would be more than willing to sell them at only slightly more than market value!

Pity you didn't figure it out five months ago before it got cold :) Good on you for getting up in the crawl space yourself. I refuse - although truth be known I'd have a hard time pulling my self up there. That and the ferret that we used to have up there. Smelly disgusting animal.

Yay you guys! You’ll be toasty warm in no time! : )

Jo- you know our woodstove has had exactly that effect. Everyone sucked teeth and shook heads over us putting one in and then when we did and people visited it was a real 'ahhhhhhhhhhhh??!' moment and now there must be....six other woodstoves in the neighbourhood! We really shot ourselves in the feet though as we have to share the firewood that much more, now huh?

GW- forget 5 months ago- how about 7 years ago!!! It never even occurred to me that there wouldn't be anything up there!

And I'm not that brave- I waited for K to scope the place out first!

Gina- yup! And by that time it will be summer probably, huh? Oh well, there's always another winter around the corner!
