Eco Window – Energy IV 78
Eco-Energy IV 78 wooden windows are modern, energy-efficient windows made from four-layer timber. The thicker 78 mm profile provides significantly better thermal insulation, reducing heat loss in the home and increasing living comfort. A key feature of the Eco-Energy IV 78 models is the use of a triple-glazing unit with a low thermal transmittance (Ug) of 0.6–0.7 W/m²K. On request, we also offer warm-edge spacers such as Termix or Swisspacer in various colors, which further enhance the window’s energy performance, improving both efficiency and comfort.

Eco-Energy IV 78 window
Eco-Energy IV 78 wooden windows combine modern energy efficiency with the durability and elegance of four-layer natural timber. The high-quality laminated wood is carefully selected and dried to optimal moisture levels, ensuring profile stability and protection against warping, which guarantees many years of trouble-free use. Additional protection and extended longevity are provided by an advanced impregnation process and a primer coating that prepares the surface for the final finish. Frame thresholds and the bottom edges of the sashes are protected with sturdy aluminium drip caps, which efficiently channel water away and safeguard critical structural elements from moisture and mechanical damage. Eco-Energy IV 78 windows are also made to individual specifications, offering full customization. Customers can adjust window dimensions and shapes, choose the timber species (pine, spruce, oak, meranti), select lacquer colors, and add functional or aesthetic features such as triple-glazing units or Termix warm-edge spacers, which maximize the windows’ energy performance.
