In cold climates, special requirements for using aluminum profiles include selecting materials with enhanced thermal performance to prevent condensation and frost. It's crucial to use aluminum profiles with appropriate thermal breaks to reduce heat loss. Additionally, consider using profiles with higher strength to withstand the contraction and expansion caused by temperature fluctuations. Protective coatings or finishes may be necessary to prevent corrosion from salt or other winter chemicals. Always consult with manufacturers for specific recommendations tailored to the climate conditions.
