How to handle materials before the Attefall house is heated?

[zannahh]

In what order should I complete the remaining tasks, and how does it work to build/store these materials in "outdoor climate," even though it's "indoors" in the cold attefallshuset?
I live on the coast in Härnösand if that makes a big difference.

The house will be heated with a heat pump, which is waiting for us to install OSB + drywall before their installation.
How do OSB + drywall behave during the construction period, as it's currently cold in the house, i.e., no heating.

Same with the ceiling, I plan to install furring strips and then Huntonit ceiling - is it a problem to have them in "outdoor temperature" for a month or so before the heating starts? It feels a bit unnecessary to have an expensive convection heater out there until the wall + ceiling tasks are complete, but if that’s what it takes...

Or is it just about biting the bullet and starting to heat a house with very expensive electricity until these interior wall and ceiling tasks are complete?

Would you install the Huntonit ceiling first or OSB + drywall first, which "end" should I start with?

The plaster is usually not a problem as it is a “dead” material. Osb and Huntoniten will swell from the moisture and dry apart when you apply heat. Then it might not necessarily cause any problems as long as it is allowed to dry out properly before you fill and paint.

Thanks! How would you have done it? Kept a convector heater running around the clock until the LVP is installed? That could take a few weeks = a bunch of money, but at the same time, it's unfortunate if materials get damaged.

I would have tried to keep at least 10 degrees in the building and then when you have the actual heat on, let it dry out for a week before you start with the surface layers.

Once it's insulated, it doesn't cost much to heat up with a convector heater. I am building a loft on top of a garage, 28 sqm, and I heat it with a small construction fan. It easily becomes 10-12° there when the fan is on the lowest setting (650w) and the thermostat is on ½ power and it was -10° outside.

Of course, no ventilation is running; only natural draft from 3 air gaps in the windows open.

Good luck with the construction. // J
