The 85 Series combines the warmth of interior composite wood with the durability of exterior aluminum, creating a high-performance outward-opening casement system ideal for cold-climate residential projects. The composite wood interior is made from 70% premium wood powder + 30% high-polymer materials, offering long-lasting stability while exceeding EU RoHS environmental standards. With no heavy metals, non-toxic composition, water resistance, Class B1 fire rating, and 20-year anti-deformation warranty, it delivers the natural look of wood without traditional maintenance concerns.
Equipped with German Roto hardware, triple glazing, and a 3-EPDM sealing system, the 85 Series achieves U-values below 1.2 and meets NAFS and Canadian Energy Star requirements. This system provides a high-value alternative to solid wood windows while ensuring reliable insulation, durability, and superior performance in harsh climates.
