BONA window in VEKA Alphaline system is our Energy saving giant. It is characterized by particularly effective and innovative 6-chamber system. There may be 6 chambers only, but their quality is excellent. The quality results from months of work in laboratories. Their structure of refined shape and system, appropriate thick external and internal walls give much better parameters than any other system with a larger number of chambers. This is the first system with installation depth of 90 mm, as they have not yet been any serial production of PVC profiles with the window frame width of 90 mm. The additional 20 mm improves “U” thermal insulation coefficient by 0.4 W/m2K, which is an excellent result. The system of three gaskets with a medial gasket ensures perfect tightness and acoustic and thermal insulation. Owing to an insulating wedge and three-pane combination, BONA windows in Alphaline systems are characterised by a remarkable heat permeability coefficient for construction of an energy saving house!
The reduced side height is 118 mm only ensuring larger pane surface and excellent additional lighting of the interior. The design ensures classical optics and balanced proportions. Owing to its toned and neutral appearance and external contours, the window can match practically all facades.
The high quality BONA windows in VEKA Alphaline systems are easy to clean and materials used for production of the same guarantee long-term use. BONA windows constitute a profitable investment in your property.
The structure of BONA windows in VEKA Alphaline system:
- 6-chamber system, class A, installation depth of 90 mm (window frame width) ensures the highest level of thermal insulation.
- The window pane set: three-pane set with a warm spacing frame of Ug = 0.6 W/m2K.
- The system of three gaskets with a medial gasket ensuring excellent protection against wind, rain and noise. Reliably seated for visually reduced width and better lighting.
- The total reduced side height for better optics and excellent lighting of the interior.
- Innovative system of fittings for greater convenience and safety.
- Long life, optimum stability and durability owing to considerable steel reinforcements.
- Easy to care of and maintenance-free window profiles without lead.
With standard 3-pane glazing of Ug = 0.6 W/(m2K) Ug = 0.6 W/(m2K), ψg = 0.05 W/(mK)

Colours
In architecture not everything has to be based on straight lines or be white. BONA windows in VEKA Alphaline system can be triangular, round or even asymmetrical. You can also order your favourite colours or double-colour variants with their internal surface made in a different colour than the external surface.
The system of fittings
BONA windows in VEKA Alphaline system are offered with Winkhaus tilt and turn fittings. Being a leader in the market and technological pioneer, Winkhaus has focused for over 150 years on quality, comfort, safety and innovation improving its technical and quality standards all the time and guaranteeing long failure-free use. Winkhaus fittings combine functionality and high comfort of use. The modern design makes them distinguish also in terms of aesthetics (it is also possible to install hinges that are invisible from the inside) giving an innovative appearance to BONA windows in VEKA Alphaline system. The hinges are invisible from the outside.
A window is one of the most frequently used “access points” for burglars in a flat or house. BONA windows in a standard variant are equipped with fittings on pins in the form of octagonal mushroom cams, which increase safety in this standard! The standard level of safety of a window may be increased, if necessary (also in our configurator) up to a class with increased WK1 or WK2 resistance.
Panes
BONA windows in VEKA Alphaline system are equipped as standard in a combined three-pane of Ug 0.6 W / m²K. Using our configurator, you can also choose a warm spacing frame, which decreases the possibility of a thermal bridge formation at the contact of the glass and frame and, consequently, the heat permeability coefficient will improve. It is also possible to choose various types of ornaments.

Latches
Each sash of BONA windows in VEKA Alphaline system is accompanied as standard by a Hoppe Secustic white aluminium latch. Its tasteful style is a real decoration for your windows. It is possible to use other latches in different colours locked with a switch or key.
Delivery
The average lead time (in Poland) is 2-3 weeks (for standard windows white on both sides). In case of windows with untypical colours and shapes, the lead time may be extended by another 2 weeks.
