Weatherproof loose timber, construction moisture.
Hello,
Weeks 21 - 22 we are going to assemble a prefabricated house from Fiskarheden and quickly make it weatherproof.
I have a feeling that the wooden frame should dry out for a few weeks before closing any walls. Are there any estimates on how many weeks are generally needed with a heater going to achieve an acceptable moisture level?
The question is kind of like: How long is a piece of string
I'm trying to plan my vacation in the most appropriate way.
Questions:
1) What are your experiences with construction moisture when raising a house?
2) Heater, dehumidifier, or both?
3) How long is that darn string?

One - Zero.
Two - Absolutely yep! I think....
Three - If you measure the distance between the middle of the string and its far end and call the value Y, you can plug it into the following formula, where Z is the length of the string: Cube root of (two raised to the third power) = Z/Y
I think this pretty much covers everything I have to offer on the question(s...)

I don't think you need either a construction fan or a dehumidifier. You will be raising the house during a period when conditions are normally optimal for wood to dry. Late spring/early summer, it’s relatively warm during the days but still with a low relative humidity.
Make sure to get the roof up as soon as possible, after that, just ventilating is probably sufficient, especially during the day. You can certainly assist with a construction fan at night, especially if it's cold, as you'll get extra good drying due to the RH dropping. If there's a concrete slab, that's what takes the longest to dry out.
Of course, it naturally depends on the weather during the critical phase when the frame is being erected.

Hi,
A tight roof is absolutely at the top of the list
Thank you for your responses.
