Traditional Nordic houses
Timber or masonry structures, ventilated foundations and later layered insulation upgrades.
Post-war Nordic housing

Energy-crisis construction
Heavier insulation, tighter envelopes and evolving vapour and ventilation practice.
Low-energy Nordic homes
Highly insulated, airtight assemblies with mechanical ventilation and complex service penetrations.
