OMNIA is VEKA’s double-flush, double-rebated uPVC system. Both internal and external faces have a flush appearance. A choice of timber-style corner detailing and contemporary finishes allows the same system to suit very different homes.
Read the OMNIA brochure ↗Flush faces inside and out create a more consistent appearance from room to garden.
Two rebates and seals form part of the system’s weather-performance design.
VEKA reports U-values as low as 0.75 W/m²K and sound reduction up to 43 dB for particular specifications; these are not standard values for every window.

Finish availability varies by system and specification.
Choose a swatch to update your design. These screen colours are a guide; compare a physical sample before ordering.
The visualiser uses a coloured exterior and white interior. Smooth, grained and dual-colour availability varies by profile, colour and fabricator; Spectrum will confirm your chosen combination.
Feinstruktur is a decorative foil with a fine, matt texture. It gives uPVC frames a finish inspired by powder-coated aluminium, with a subtle surface texture rather than a timber-grain effect.
VEKA describes the foil as durable, low maintenance and easy to clean, with an anti-fingerprint finish. It is still a uPVC window: frame construction, glazing and hardware determine the window’s performance.
Explore VEKA’s Feinstruktur information ↗For Rustique or Halo FlushSash, ask Spectrum to check the exact profile and finish combination. It is not offered as a selectable option for those systems here.
Select System 10 or OMNIA in the visualiser to try these finishes.
Swatches illustrate colour only. The on-screen texture is an approximation, not a physical finish sample.
Choose a handle style and finish. Your visualiser switches to the inside view so you can see your selection.
Handle styles and finish combinations are indicative, subject to supplier availability and compatibility with the chosen sash and locking system. Confirm locking, key access and any escape-window requirements at survey. Fixed panes do not have handles.
