When upgrading windows and doors, most homeowners focus on individual openings. The front door, the kitchen windows, the French doors at the back. Each gets chosen separately, sometimes from different ranges or even different manufacturers. The result can be a home where the windows and doors look close enough to matching, but never quite the same. Profile depths differ. Shadow lines vary. Finishes are slightly off. It is a subtle inconsistency, but once you notice it, you cannot unsee it.
OMNIA Flush solves this by offering something no other system on the Irish market currently does: a complete suite of matching flush windows and doors, all from the same profile family, in the same finishes, with the same design language throughout.
What flush means and why it matters
In a flush window, the sash sits level with the outer frame rather than projecting forward from it. This creates a clean, flat surface on the exterior with no stepped profile. The result is a more refined, contemporary appearance with slimmer sightlines and a subtle shadow line where the sash meets the frame. There is no visible black rubber gasket on the face of the window, which is a common visual weakness in standard uPVC systems.
This flush aesthetic has traditionally been associated with timber and aluminium. OMNIA Flush brings the same design quality to uPVC, offering the look and feel of more expensive materials with the durability and low maintenance that uPVC provides.
One system across every opening
The real strength of OMNIA Flush is its range. The system covers casement windows, tilt-and-turn windows, entrance doors, and French doors, all sharing the same profile geometry, the same finishes, and the same hardware styling. When your front door, your kitchen windows, and your rear French doors are all specified from the same system, the visual continuity across the home is immediate and complete.
This matters more than most people expect. Architectural consistency is one of the things that separates a home that looks thoughtfully designed from one that looks like a collection of individual upgrades done over time. With OMNIA Flush, every opening in the house speaks the same design language, inside and out.
Colour and finish options
OMNIA Flush is available in over 20 colours and finishes, including classic whites and creams, contemporary greys such as agate and anthracite, warm woodgrain effects like Irish Oak, and modern tones like sage green and ulti-matt black. The range also includes Fine Texture Foil finishes, which add a finely textured, premium surface quality that brings depth and tactile appeal to the profile.
Because every product in the OMNIA Flush suite draws from the same colour palette, you can confidently specify different product types in the same finish across the house, knowing they will match precisely.
Performance behind the design
OMNIA Flush is not just a design story. The system achieves U-values as low as 0.75 W/m²K with triple glazing, placing it comfortably within passive house territory. Multi-chambered profiles provide structural strength and thermal insulation. Every unit is certified to PAS 24:2022 for enhanced security, and the system is rigorously tested for air permeability, water tightness, and wind resistance.
The innovative construction of OMNIA Flush also allows for faster fabrication and installation times compared to traditional flush systems. This means less disruption during the installation process and shorter lead times from order to completion, without any compromise on quality.
A timber and aluminium alternative
For homeowners who love the aesthetic of timber joinery or the clean lines of aluminium but want the practical benefits of uPVC, OMNIA Flush offers a compelling middle ground. The flush profile, the natural shadow line, and the range of matte and textured finishes deliver a visual result that stands alongside timber and aluminium, with none of the ongoing maintenance that timber demands and at a more accessible specification than full aluminium systems.
See OMNIA Flush in person
OMNIA Flush is one of those products that makes its strongest impression in person. The flush profile, the shadow line, and the quality of the finishes are best appreciated by seeing and touching the product rather than reading about it. Full OMNIA Flush displays are available in Fairco’s Santry and Deansgrange showrooms, where you can compare finishes, operate the hardware, and see how the system looks across windows and doors together.
