Omnia Flush Sash Windows….Innovation reinvented!

The next generation of Flush Sash Windows represents a significant leap forward in design, functionality and performance. Combining cutting edge technology with a new double rebated design to offer superior benefits over previous Flush Sash systems. The Omnia range, while retaining the timeless aesthetics of traditional Flush Sash designs, are now optimized for modern living, with greater emphasis on energy efficiency, sustainability, security, and user convenience.

Omnia’s Double Rebated Seal

This is a real game-changer in the Flush Sash market. A double rebated seal consisting of two overlapping seals compared to the first generation Flush Sash Windows that only have a single rebate seal and an external gasket to fill the air gap. The double barrier greatly enhances resistance to wind, rain and drafts, and this is especially important in areas with extreme or variable weather. The double seal not only prevents air infiltration but also creates an extra thermal barrier to improve overall thermal performance.

It just makes sense!

A double rebated seal offers a clear advantage over a single seal with an air gap gasket in key areas like weather & sound proofing, thermal insulation, and overall performance. Whilst a single rebate system is good, the double rebate is the superior choice for those seeking optimal performance.

Better U’ Values

Omnia Flush Sash Casements promise superior standards of energy saving, weather protection, and acoustic performance. The system promises excellent thermal performance properties when glazed with triple (0.79 W/m2K) or double (1.2 W/m2K) glazed units.

Flush Design inside & out

Another unique and distinct design feature on the new Omnia Flush Sash Window is the flush sash appearance now comes both inside and out. On the exterior, the flush finish maintains a classic appearance, often mimicking the traditional timber window look, which is especially important for period properties or homes in conservation areas. On the interior, the flush sash sits level with the surrounding wall or trim, creating a more cohesive and streamlined look, ideal for modern interior design where clean lines and symmetry are valued.

Omnia Flush Sash Windows are pioneering and a quantum leap in design choice. The Omnia range is highly desirable to satisfy the growing demand for Flush Sash Windows. Omnia combines the perfect balance of timeless elegance and 21st century performance.
