Materials + finishes
Every Fenstür product is available in all-wood or wood-aluminum-clad construction, with species, grain, colour, sheen and hardware selected around the architecture and exposure.
Two exterior expressions
Both begin with the same engineered timber structure and the same warm, genuine-wood interior. The choice is about exterior expression, exposure, maintenance and budget.
Compare materials + finishesSolid laminated components are used across windows and doors to improve stability, strength and predictable movement while preserving real-wood surfaces.
Douglas fir, hemlock, true firs, cedar, oak, maple, alder, walnut and specialty species can be selected around colour, grain and availability.
No Paint, Clear Coat, UV, Ebony, Walnut, Douglas, White and Black form the standard starting palette.
Fenstür can match an approved customer paint or stain sample, including split interior and exterior appearances where the system allows.
A controlled, multi-stage coating process protects edges, joints and concealed surfaces before glass and hardware are installed.
Wood species
Fenstür builds with domestic and specialty species selected around grain, colour, finish and availability. Laminated engineered components are used throughout the product range for stability, strength and more predictable movement.
Wood varies naturally in colour, grain and figure. Final selections are confirmed with current physical samples.
Warm colour and a clear, expressive grain.
Light, quiet grain suited to contemporary work.
Pale, even character with a calm interior presence.
Durable with a strong, straight architectural grain.
Open grain and a warmer, more pronounced figure.
Light colour with subtle natural figure.
Warm tone and deliberately visible knots.
Rich colour and a distinctly West Coast character.
Pale, fine-textured and naturally refined.
Deep brown colour for feature openings and doors.
Other species are available by request. Confirm current suitability, grade, lead time and approved finish samples with Fenstür.
Standard colour options
These screen swatches are illustrative. Wood species, grain, sheen and display settings change appearance, so approved physical samples govern the final finish.
These finishes retain the character of the wood. Species and grain change the final colour, so an approved physical sample governs.

Fenstür uses solid laminated timber components throughout its window and door systems. Laminating selected pieces improves strength, stability and resistance to movement while preserving the warmth, grain and repairability of genuine wood.
Why wood
Compared with PVC or vinyl frames, engineered timber offers the rigidity needed for large openings and heavy high-performance glass, along with the ability to repair or refinish the visible surface over time. It also gives architects far more freedom in species, profile, shape and colour.
All wood
All-wood construction preserves the natural material inside and out. Species, exposure, detailing, finish colour and maintenance expectations should be considered together.
Wood-aluminum
A separated, ventilated aluminum skin protects the timber from sun, rain, wind and dirt while leaving the full character of wood visible inside. The cavity behind the cladding helps incidental moisture dry and limits direct thermal bridging.
Factory finishing
Preservatives, sealers, stains and paints are applied in a controlled environment, including areas that become difficult to access after glazing and hardware installation.
Frequently asked
Wood is chosen for architectural authenticity, natural warmth and design freedom that vinyl cannot fully reproduce. Its strength supports slim profiles, large openings and heavy glass, while its natural insulating qualities help limit heat transfer through the frame. Wood can be painted or stained to coordinate with interiors, cabinetry and historic architecture—and refinished when tastes change. With regular inspection and proper finish maintenance, a well-made wood window can last for decades and damaged surfaces can often be repaired rather than replaced. For highly exposed elevations or lower-maintenance priorities, Fenstür also offers wood-aluminum-clad construction: real wood inside with a durable protective exterior.
Custom colour and stain matching is available. Because wood species, grain and light affect the result, physical samples and an approval process are recommended.
Transparent exterior finishes benefit from some pigment because it improves UV protection. Exposure and maintenance expectations should be reviewed before selecting a fully clear exterior.
