Superlative wood-aluminium windows.

“Finstral offers you an intelligently designed wood-aluminium window: with a recyclable uPVC profile instead of wood in the functional zone.”

Easy-care rather than solid wood.

Wood is a fabulous material with an unmatchable warm, homely feel. Yet, it is not ideal for window construction. This is because wood weathers. Protection can be provided by painting or varnishing, though recoating is required every few years. And the coated finish turns natural wood into a non-recyclable composite material. Which is why Finstral only uses real wood on the non-weather-exposed, interior side of its windows. Oiled or treated with a water-soluble coating. The result is a durable, low-maintenance window that nonetheless retains a warm, homely feel.

Slender frames with every design.

Narrow frames are characteristic of wooden windows. While Finstral windows faithfully assume this guise, their exterior is never made of wood. Instead, we use truly weather-resistant materials such as aluminium – with a strikingly realistic wood-decor finish on request. This requires little care and low maintenance, yet takes on the appearance of a typical wooden window.

The best of three worlds – aluminium, uPVC and wood.

Insulating core comprising multi-chamber uPVC profile with welded corners
Weitere Informationen
The uPVC core is completely water-resistant and thus rot-proof. The welding process also vouches for a watertight barrier at the frame corners.
Insulating wood core with mortise-jointed or glued corners
Weitere Informationen
The wood in the core can absorb moisture and thus swell or warp. Nor can mortise or glued joints guarantee a permanent watertight barrier.

Largely recyclable
Weitere Informationen
Lead-free uPVC and aluminium facing are fully recyclable. Interior wooden facing with water-soluble coating is downcyclable.
With only limited recyclability
Weitere Informationen
Aluminium facing is fully recyclable. To be weather-resistant, wood requires treatment, e.g. with a synthetic coating. Consequently, at the end of the window’s service life, it is only fit for thermal recycling.
No risk of the wood component causing the window to warp
Weitere Informationen
Wood “works”, i.e. expands and contracts. In Finstral windows, it serves an aesthetic rather than a structural function. Any risk of warped wood impairing the window’s functional performance is thereby eliminated.

The intelligent wood-aluminium window.

Make painting a thing of the past. Finstral’s wood-aluminium windows combine the homeliness of real solid wood (on the interior) with the resilience of aluminium (on the exterior). The true ingenuity is hidden from view: a perfectly insulating uPVC core that doubles up as a weathertight barrier. The major benefit is that the wood in Finstral products does not accommodate any structural loads and is weather-protected, so it cannot warp or rot. Thus guaranteeing wood finishes with lasting appeal and no maintenance requirement.

FAQ

Is a wood-aluminium window just as robust as a traditional wooden window?

Yes. In fact, it is even more stable than a solid-wood window. Structural strength is provided by the steel-reinforced uPVC core. As the wood is not subject to any loads, it cannot warp. Which means the window will never “stick”.

How do I clean the wooden frames on the interior?

Wiping with a well-wrung cloth without any aggressive cleaning agents will suffice perfectly. As we use premium-grade, water-soluble coatings, the finishes are highly resistant to dust and finger marks.

How much do wood-aluminium windows cost?

Each window is unique and the price depends on many different factors: size, materials, glass, security options etc. For a personalised quotation, please contact us at finstral.com/contact.
