Top Trusted Aluminum Clad Wood Windows Manufacturers & Factory

In premium systems, the aluminum skin does not rest directly on the wood frame. Direct contact would create thermal bridging, trap condensation, and cause premature rot. DERCHI utilizes engineered, high-tensile composite nylon mounting clips that maintain a continuous 5mm to 8mm isobaric rear-ventilation cavity between the extruded aluminum outer shell and the multi-laminated solid wood frame. Any moisture driven into the weep tracks is immediately discharged via calibrated drainage slots, while air circulates continuously to equalize atmospheric humidity.

Extruded aluminum (6063-T6) exhibits a coefficient of linear thermal expansion of roughly $23 \times 10^{-6}\text{ K}^{-1}$, whereas natural wood parallel to grain expands at only $3 \times 10^{-6}\text{ to }5 \times 10^{-6}\text{ K}^{-1}$. To prevent buckled frames or shear stress on the joinery, our cladding system features floating snap-in clips with longitudinal slide tolerance. This allows the outer aluminum skin to expand and contract freely along its perimeter during extreme summer-to-winter temperature swings without exerting load on the timber core.

We recommend 3-ply or 4-ply radially cut engineered finger-jointed timber profiles. For standard cold to temperate climates, Northern European Scots Pine (Pinus sylvestris) or Siberian Larch offer natural tensile resilience and value. For high-humidity coastal estates and desert villa projects, American Red Oak, Teak, or FSC-certified Sapele deliver higher density, natural rot resistance, and exceptional grain character under microporous, water-based anti-fungal stains.

DERCHI collaborates natively with global hardware engineering leaders including German Roto Frank, Siegenia-Aubi, and HOPPE architectural handles. Our tilt-and-turn and inward-swing casements utilize circumferential multi-point mushroom-head locking cams constructed from high-tensile carbon steel, delivering RC2 / RC3 European burglary resistance standards while ensuring uniform compression around all perimeter acoustic gaskets.

Every completed unit undergoes full workshop pre-assembly, laser squareness verification, and dynamic operational testing prior to crating. Glass panes and frame faces are wrapped in protective polyethylene scratch films, padded with high-density EPE corner protectors, hermetically sealed inside shrink wraps with desiccants, and packed into reinforced fumigated IPPC-grade multi-layer plywood export crates engineered for ocean container transfers.
