Greenhouse Construction
for Northern Poland
Structural and material reference for building greenhouses in regions where winter temperatures regularly fall below −15 °C and frost depth exceeds one metre.
Construction Essentials
Three areas that determine whether a greenhouse survives a Polish winter in working condition.
Cold Frame Foundations for Polish Greenhouses
Frost depth in Poland ranges from 0.8 m in the west to over 1.4 m in Podlaskie. Foundation type determines how the structure behaves through freeze-thaw cycles.

Polycarbonate vs Glass in Cold Climates
Snow load requirements, U-values and condensation behaviour differ significantly between twin-wall polycarbonate and tempered glass in below-freezing conditions.

Heating Options for Northern Poland Greenhouses
Hot water pipes, biomass boilers and ground-source heat are the three systems most commonly found in year-round growing operations in the Mazury and Podlaskie regions.
ReadWhat This Site Covers
NorthCedarLine documents construction approaches for greenhouses in Poland’s colder climate zones. The content focuses on structural decisions that have direct consequences in temperatures below −10 °C: foundation frost protection, glazing material selection, and heating system comparison.
Poland’s climate is classified as humid continental (Köppen Dfb) across most of the north and east. Design decisions that are adequate for western European greenhouses often do not transfer directly to structures that must handle 120–160 frost days per year.
