In architecture, the door plays a very important role: in relation to the complexity of a building, it could be considered a secondary, instrumental element; yet it constitutes the first contact with the structure: through the door one has access to other 'worlds'. Window and doorframe companies have the task of having to innovate on an aesthetic, technological and symbolic level this element, following the constant changes in our way of living and understanding the home. Oknoplast is well aware of this, and for some time now has been offering Tenvis aluminium entrance doors on the market, highly performing and resistant, on which the functional and practical aspect is flanked by the experimentation of a more refined and innovative aesthetic year after year. 

Tenvis Black Design is the company's latest proposal, characterised by its great visual impact: the inserts, decorations and anodised handle, emphasised by the black colour, give the product a bold elegance. The collection consists of 12 different models; thanks to the wide range of finishes and wood effects, it is also possible to customise the door to your liking, even choosing the two-tone option.

Like all of Oknoplast's Tenvis aluminium proposals, Black Design is equipped with very thick slabs that guarantee absolute sturdiness to the structure. In addition, the extruded polystyrene XPS thermal cladding inside guarantees high fire resistance and improves the house's energy saving (Ud = 0,84 W/m2K).

In addition, the new Black Design line can also be equipped with various security features, such as the automatic lock that allows the door leaf to be locked at three points, without using a key, or the ring escutcheon that provides additional protection against burglary attempts. Finally, the new Oknoplast door is compatible with the most advanced Smart Home systems and equipped with some of the most high-tech opening systems such as the fingerprint reader, in addition to the classic smartphone or remote control.
