While the cement guys are busy with the floor heating and the cement top layer, we continue working on the roof. This house gets a metal roof. Metal roofs used to have a somewhat mixed reputation. Cool and techy, but also a little, well, shoddy.
We place our wooden walls straight on the concrete foundation, and then, between our walls, the cement & concrete guys add a few extra layers:
- floor heating
- chape, or cement
- optionally: tiles, or a wooden floor.
In this house we don’t do layer 4. No tiles, no wood, just cement on top. Looks cool and modern, and contrasts nicely with the wooden walls. Just a matter of preference. The combination of floor heating and a wooden floor is a little unusual, but we have wooden floors that are specially engineered to be combined with floor heating.
The main problem with this floor? Layer 3: the cement. We need to bring a 35 tonnes cement mixer to the island, on a pontoon. Today was pontoon day.
We start with a floor like this: concrete load bearing base, then insulation, floor heating (that’s the yellow lines), steel grid.
Adding the insulation on the outside has started. We are lucky with the weather, no rain at all. Having rain while doing the insulation works is not impossible and the insulation will dry without any problem, but it is easier to install it in dry conditions.
With the nice weather works are progressing very rapidly. The roof is closed, no more rain inside the house. Not that it rains anyways, we haven’t seen any rain in the last three weeks. Next week we will put the Ruukki metal roof on top. First however we will finish the roof bottom, and we will place the insulation on the outside, and then cover with larch. Zero maintenance, lasts a lifetime.
