Weather forcast for next week

Karasjok (north Norway), Wednesday next week: 40 degrees below zero. No need to tell whether it is C or F. They are used to low winter temperatures in that area. Some years ago, with -52C, there was a fear that the power grid would break down (it didn't happen, but people joked that street lights were not needed - the glow from the power lines gave enough light). On TV, the mayor was asked what would be the consequence of a breakdown, and he answered with a perfectly straight face: Well, that would significantly reduce the difference between indoor and outdoor temperature.

:) good answer, mayor reminds me of northern mn in winter can be dangerous if not trained for it

I spent a high school year in MN - not up north, but near Redwood Falls; the winters can be quite bad there, too. Coming from Norway, I was shocked to see quality of insulation ("Insulation", what's that?? :-)) in most houses. Sofas and chairs were moved away from outer walls, to the center of the room, to stay away from the ice cold walls. On the other hand, all houses had impressing huge oil furnaces. This was in the late 1970s, and the houses were not put up last year. So things may have changed - although rumors are "Not that much!" Certainly, if the houses I saw then are still standing, I doubt that they have torn down the walls to add 12 in thick fiberglass mats in all outer walls and replaced the windows with 3-layer ones. If insulation is better nowadays, I expect it for new buildings, mostly. I am today living in a 1959 vintage house. Even that far back, it was built with 8 in insulation mats in the wall (although that was 'high standard' in 1959). Last time I referred to this, someone pointed to Canadian building standards, that are comparable to the Norwegian ones. I guess that enforcing such standards, even in MN, would be an unacceptable limitation of personal freedom :-).

Yeah, Redwood Falls gets those cold fronts coming across great plains from Canada. Brrrr. I recall your previous discussion comparing insulation in Norway vs US. Your observations are good. The new homes in Mn, especially northern parts, are now built with insulation everywhere. Floors, walls, etc. Many furnaces still use oil, but there more using gas and/or electricity. insulation is key. Some of the older homes (not controlled by code) still use a paper-like insulation. Actually works well if done right.

I wonder if anyone building a new house would consider incorporating a hypocaust - it may be old tech, but it certainly works! Is fibreglass insulation the norm nowadays? I live in a tropical country - so... "insulation?! what's that?" :-)

A politician that is both competent and intelligent. Better take a picture.

Here in Norway, it is the "norm", in the sense "most used". That is is what you compare the other alternatives to. I believe that #2 is the stuff with brand name "Rockwool" - I do not know the generic name. Its insulation qualities is similar to glass wool, but it is heavier, so if you live nearby a noisy road, it will give you better noise insulation. It also is practically speaking non-flameable; glass wool isn't too bad in case of a fire, but rockwool is better. Variants of styrofoam are used, but in a fire it burns badly and can release toxic gases. So styrofoam is mostly used e.g. under concrete basement floors, protected against open fire. Between the basement floor and the ground you would usually use pebbles of expanded clay aggregate, commonly known as "LECA". I am planning an extension of my house; to satisfy the modern requirements of U-value < 0.1 for a floor (i.e. a loss of less than 0.1 W per square meter per delta K), I could use e.g. 30 cm LECA topped with 25 cm styrofoam, or 40 cm LECA and 20 cm styrofoam; styrofoam is almost three times as good an insulator as LECA, but a lot more expensive. In the old days, outer walls were sometimes filled with sawdust, which is also a good (not excellent) insulator. In the old days, every farm had a wood saw, so the cost was next to zero. The problem is if it gets wet and start to rotten. Today, there are numerous high-tech (read as: high cost) alternatives. None of them are ready to knock out glass wool as what everything is being compared to. The biggest heat drain in the outer walls is the windows. So the maximum allowed U-value of 0.8 W/sqm*K requires, for all practical purposes, 3 layers of glass. Also, there is a strong focus on draft as an energy thief. For new houses, you will be living inside a sealed plastic bubble where no air can get in or out except in a very controlled manner through a ventilation system. At the final acceptance test for a new building, they actually do close all windows and vents and set the house under pressure to see if more air leaks out than what is tolerated. I am happy to live in an old house that is not a plastic bubble, even though it does leak some air out in winter, and in at other times of the year. (Nor am I obliged to honor that U<0.1 requirement for the basement floor of my extension, but I will do it to save on my power bill!)
