Mylch Solid Timber Systems Engineered for Performance. Certified for Comfort.
Windows of timber are the breathing skin of architecture, and a century-old art of living. We source premium lumber from around the globe, blending rigorous German engineering with modern technology to perfectly unite the warm, natural texture of wood with ultimate thermal and acoustic performance. Weatherproof on the outside, luxurious on the inside, we craft bespoke, high-end "eyes of architecture" that harmonize ecological aesthetics with cutting-edge technology.
Mylch Solid Timber Windows: Evolution & Craftsmanship
Mylch’s deep bond with timber windows represents nearly three decades of technological evolution. Ever since we first introduced German style pure timber windows filling a major void in the domestic market, we have constantly innovated to ensure the warmth of wood can endure the test of time, while fulfilling modern architecture's demand for expansive, open spaces.

To counteract severe outdoor sun and rain, Mylch pioneered wrapping a high-strength, aviation-grade aluminum alloy profile over the solid wood exterior. This "weatherproof aluminum outside, insulating timber inside" design masterfully balances robust wind resistance with a warm, cozy interior aesthetic, ushering in the era of high-end aluminum-clad timber windows in China.

Driven by modern architecture’s pursuit of massive glass panes, seamless panoramic views, and passive ultra-low energy consumption, Mylch has further evolved its heavy-duty aluminum-clad timber systems. Combining extra-thick frames with multi-cavity exterior aluminum, these systems effortlessly support larger, heavier multi-layer glass. It is not just a revolution in window longevity, but a bespoke "spatial armor" tailored for modern luxury estates, grand wide-span facades, and extreme weather conditions.
