Kulmasaumat

Kulmasaumat is a Finnish term referring to standing seam metal roofing. It is a roofing system characterized by raised, interlocking seams that run vertically along the roof. The term "kulmasaumat" directly translates to "corner seams" or "edge seams" in English, highlighting the prominent nature of the seams in this roofing style. This type of roofing is known for its durability, longevity, and aesthetic appeal.

The construction of a kulmasaumat roof involves panels of sheet metal, typically aluminum, zinc, copper, or steel, that are joined together using a series of interlocking folds or seams. These seams are elevated above the roof deck, creating a channel that effectively sheds water and prevents leaks. The panels are often concealed-fastened, meaning the fasteners are hidden beneath the seams, contributing to a clean and seamless appearance.

Kulmasaumat roofing is highly resistant to wind uplift, extreme weather conditions, and fire. Its longevity can extend for 50 years or more with proper installation and maintenance, making it a cost-effective long-term roofing solution. The aesthetic versatility of kulmasaumat is also a significant advantage, available in a wide range of colors and finishes to complement various architectural styles. It is a popular choice for both residential and commercial buildings, valued for its performance and visual impact.
