Watti Energy Windows

Lammin Watti energy windows can be implemented in several different energy classes, depending on the choice of glass: A ++, A + A or B. Watti energy windows are well suited for new construction and renovation.

Watti energy windows are suitable for home and year-round warm cottage

Lammin Watti windows are designed to keep the once produced heat inside the home. That is why Watti is a good window option for homes and year-round holiday homes. The Watti energy window is commonly used in both renovation and new construction. The structures outside the window are made of aluminum-coated wood. Aluminum cladding makes the window maintenance-free and very weather-resistant.
