Flush Inside, Flush Outside: The Next Step in Window Design

When it comes to upgrading your home, windows are often one of the most transformative changes you can make. Not only do they influence how your property looks from the outside, but they also shape the way your living space feels on the inside.

For years, flush casement windows have been a popular choice for their clean lines and subtle design. But what if you could take that elegance even further – with windows that are flush both inside and out? Enter Omnia – the Ultimate Dual Flush System.

What Does “Flush” Really Mean?

In traditional casement windows, the sash (the part that opens) sits slightly raised from the outer frame, creating a step. With a flush window, the sash sits level with the frame when closed, giving a sleek, streamlined appearance.

This design not only looks smart but also suits a wide range of homes — from period properties wanting a timber-like aesthetic to new builds chasing a more contemporary style.

Until recently, though, “flush” has always been an external feature. Inside, homeowners were still left with the stepped appearance of a standard frame.

Internal Flush – Why It Matters

With Omnia, things are different. It’s the first dual flush system on the market, designed to give you:

  • A true flush appearance both inside and outside

  • Clean, minimalist lines throughout the home

  • A premium finish that blends seamlessly with modern interiors

For homeowners who appreciate detail, the internal flush makes a big difference. Walls, décor, and window lines flow effortlessly, with nothing breaking the smooth visual effect.

Style Meets Performance

Of course, windows should never be chosen on looks alone. Omnia is about more than just style. It’s a double rebated system, which means it has extra seals for improved insulation, weather protection and security.

This innovation means you don’t have to compromise:

  • Energy efficiency – keeping heat in during winter and reducing bills

  • Noise reduction – a quieter, calmer home environment

  • Enhanced security – with robust multi-point locking systems

  • Durability – built to stand the test of time

Colour and Finish Options

As with all premium window ranges, Omnia is available in a curated palette of colours and textures, from timeless whites and greys to woodgrain finishes that emulate traditional timber.

And if you prefer flexibility, many frames can be coloured outside with a neutral white finish inside — ensuring they always work with your interior décor.


The Future of Window Design in Your Home

For decades, the choice in window style has been relatively straightforward: standard casement, flush casement, or perhaps a timber alternative. Omnia represents a new direction — one that combines:

  • Design innovation – flush inside and out

  • Engineering excellence – double rebates, security and performance

  • Personal choice – colours, foils, and hardware to suit your home

It’s a prestige product for homeowners who want to invest in long-lasting quality and next-level design.
