OMNIA Flush Windows

The next generation of flush windows for beautiful Scottish homes

If you're looking for a window that combines timeless style with exceptional modern performance, OMNIA Flush Windows deliver on every level.

Unlike traditional flush windows, OMNIA features a true double flush design, creating a perfectly flat appearance both inside and outside your home. The result is a beautifully refined window that complements everything from period cottages and Victorian homes to contemporary new builds.

Behind the elegant appearance lies cutting-edge engineering. OMNIA windows provide outstanding thermal efficiency, enhanced weather protection, impressive acoustic insulation and advanced security, all while allowing more natural light into your home thanks to their slimline frames.

Whether you're replacing ageing timber windows or upgrading existing uPVC, OMNIA offers one of the most advanced flush window systems available today.

Why Choose OMNIA Flush Windows?

Most flush windows use a single rebated design, meaning there is a single weather seal between the opening sash and the frame.

OMNIA takes performance one step further.

Its innovative double-rebated construction creates two weather seals rather than one, improving insulation, reducing draughts and offering superior resistance against Scotland's challenging weather conditions.

Combined with a true flush finish on both sides of the window, OMNIA delivers exceptional performance without compromising on appearance.

Double Flush Design

One of the defining features of OMNIA is its true flush appearance inside and out.

Where many flush windows only appear flush externally, OMNIA creates clean, elegant sightlines on both sides of the frame.

This minimalist aesthetic perfectly replicates the appearance of traditional timber windows while offering all the benefits of modern uPVC technology.

Whether viewed from your living room or from the street, OMNIA creates a beautifully balanced finish.

More Glass. Less Frame.

Natural light transforms a home.

OMNIA has been designed with slimmer frames that maximise the glazed area, allowing more daylight into your property without increasing the overall window size.

The result is:

• Brighter rooms
• Cleaner contemporary sightlines
• Better outside views
• A lighter, more spacious feeling throughout your home

Outstanding Energy Efficiency

With energy prices remaining a concern for homeowners, choosing efficient windows has never been more important.

OMNIA windows achieve outstanding thermal performance.

Double Glazing

U-Values from 1.2 W/m²K

Triple Glazing

U-Values as low as 0.75 W/m²K

Excellent insulation helps your home retain heat during winter while reducing unwanted heat gain during warmer months.

That means greater comfort throughout the year and potentially lower energy bills.

Advanced Weather Protection

Scottish weather demands windows that can cope with driving rain, strong winds and changing temperatures.

OMNIA's double-rebated frame creates two independent weather seals.

This enhanced sealing system helps:

• Reduce draughts
• Prevent water ingress
• Improve insulation
• Increase long-term durability

For homeowners, that means confidence whatever the weather.

A Quieter Home

If you live near a busy road, school, railway or town centre, outside noise can quickly become frustrating.

When paired with high-performance glazing, OMNIA offers excellent acoustic insulation, helping reduce external noise and creating a quieter, more relaxing home.

PAS 24 Security

Beautiful windows should never compromise on security.

OMNIA windows are manufactured to meet PAS 24 enhanced security standards, providing increased resistance against attempted break-ins.

Combined with high-quality locking systems and robust construction, you can enjoy complete peace of mind.

Invisible Mullions

A feature unique to OMNIA is its invisible mullion design.

Where traditional window systems often have bulky vertical sections interrupting the view, OMNIA creates a cleaner, less obstructed appearance.

This contributes to its elegant aesthetic while maximising the amount of visible glass.

Built to Last

OMNIA windows are manufactured using durable, low-maintenance uPVC that won't rot, warp or require regular painting.

They are designed to withstand years of daily use while maintaining their appearance and performance.

Premium Feinstruktur Finishes

For homeowners wanting the appearance of powder-coated aluminium without the maintenance, selected colours are available in Feinstruktur.

This premium textured foil creates a beautifully matt finish while offering outstanding resistance to:

• Scratches
• Knocks
• Everyday wear
• Cleaning chemicals
• Alcohol-based cleaners

It provides a luxurious contemporary appearance that's exceptionally hard-wearing.
