Solid wooden windows that combine excellent thermal insulation, burglary resistance, and acoustic comfort with the natural aesthetics of rustic reclaimed old wood. These custom reclaimed wood windows from the ALPIN series are single-frame constructions made of solid laminated timber. Every single wooden window frame is designed with an 82 mm thickness to ensure maximum stability. Corner joints of these wood window frames are made with tenons, which is the foundation of structural stability and confirms that the product is made using proven technology. The sash structure of each antique wood window is designed as a beadless construction, which is a unique solution in this type of product on the market This solution significantly enhances visual appeal by fully exposing the natural structure of the material. The outer surfaces of the frame and sashes are clad with slats made from carefully selected old wood — each element retains the unique texture and color of the original material. The finish consists of a three-coat hydrophobic system based on water-based coatings with a matte surface, highlighting the natural wood grain.

ALPIN old wood windows combine the aesthetics of historic material with technical performance that meets the latest standards of energy-efficient construction. A structure of solid laminated timber with an 82 mm frame thickness, with tenon corner joints, ensures stability and durability of the entire construction. Exterior slats made of carefully selected old wood retain the unique texture and color of the original material — making every window one of a kind.
If you are looking for an authentic antique wood window frame that offers modern insulation, our products are the perfect choice. We also specialize in matching reclaimed windows and doors to create a cohesive look for your entire property.
The standard 40 mm glass unit with low-emissivity coating and argon filling achieves a thermal transmittance value of Ug = 0.6 W/m²K. In the upgraded 44 mm version, Ug = 0.5 W/m²K is achieved. The warm-edge SWISSPACER spacer (λ = 0.19 W/mK) eliminates thermal bridging at the glass edges.
Protection from noise in all conditions — road, air, industrial, or municipal — is ensured by installing insulating glass units with acoustic performance up to Rw 43 dB. This solution is recommended for buildings in high-noise zones.
Each ALPIN series window is made individually according to the client’s dimensions and specifications. We produce rectangular, arched, trapezoidal, and triangular windows — in single-sash, double-sash, and triple-sash configurations, with fixed mullions or floating mullions (movable mullions). The construction supports various opening systems: side-hung, tilt, tilt-and-turn, tilt-and-slide (PSK), folding, and sliding HS. Horizontal divisions are also available: single-row and double-row with transom.
ALPIN windows fit perfectly into the architecture of Alpine houses, mountain lodges, chalets, historic townhouses, and modern residences where a combination of historical character and functionality is valued. They perform well both in new buildings and in the renovation of conservation-protected properties.
To complete your rustic interior, consider pairing your new windows with our old floor boards or decorative beams and rafters.
Every wood window in our collection is crafted with care. The exterior slats of the window frame wood come from carefully selected old wood, ensuring a unique and rustic appearance. New softwood forms the modern profile. The structural core provides full mechanical and thermal performance, while the external cladding preserves the authentic character of old wood.
We manufacture windows in any shape: rectangular, arched, trapezoidal, triangular, circles, semicircles, and multi-sash combinations with fixed mullions or floating mullions (movable mullions). Every window is made to the client’s individual dimensions.
The standard is a 40 mm triple-glazed unit (4LE/14/4/14/4LE) with argon and a warm-edge SWISSPACER spacer, achieving Ug = 0.6 W/m²K. In the 44 mm version, Ug = 0.5 W/m²K is achieved. IGU thickness range: 24 to 44 mm.
Yes — we offer hardware in RC1 and RC2 classes in accordance with PN-EN 1627:2011. RC2 requires P4A anti-burglary glass. A lockable handle or push-button handle is required in higher-resistance-class windows.
We offer five variants: low wooden threshold (German), high wooden threshold (Belgian), aluminum SPREE 24OF, wooden overlay, and low aluminum balcony threshold.
