Timber houses are particularly popular in areas with large fluctuations in temperature because they provide their own heat insulation. In the summer timber does not bring the warm outside air indoors and in the winter it does not take the warmth inside outside. Consequently, the constructions that separate the inside from the outside require the use of much less material than in the case of brick houses, which means less work and less cost.

Timber does not absorb the warmth from the heating, so that a timber construction requires less heating capacity to ensure pleasant living conditions.
