Climate & code · Gipuzkoa
Gipuzkoa is one of the rainiest areas in Spain, with a very humid Atlantic climate and mild temperatures. A window with an excellent weather rating against rain, plus corrosion-resistant hardware, is the way to go.
Under the Spanish building code ( CTE DB-HE1), Gipuzkoa is climate zone D1 — cold winter, mild summer.
A new or replacement window in Gipuzkoa must not exceed Uw 1.8 W/m²K. Summer is mild here, so the priority is high-insulation glazing .
