RLM OMNIA FLUSH WINDOWS
Omnia Flush Windows
Offering many options just like our casement windows, our Omnia systems can be manufactured to suit your exact requirements, delivering an elegant range of characteristic features with pioneering double-flush design and timeless style for any property.
Modern Omnia Flush Windows can be a striking feature in any contemporary, stylish home. However, by adding something as simple as a heritage bar through the centre of the glass, your Omnia Flush Window can be instantly transformed into a period-style design—perfect for a more traditional property and ideal for replicating the look of classic timber windows.
Omnia Flush Windows by RLM: Bespoke Design Meets Performance
Omnia Flush Windows are modern uPVC windows that combine the timeless elegance of traditional timber windows with the performance benefits of contemporary glazing technology. These bespoke, fully made-to-measure windows feature a pioneering double-flush design and are engineered to deliver exceptional thermal performance, superior acoustic insulation and weather protection. Omnia Flush Windows are ideal for both contemporary homes seeking a sleek, minimalist aesthetic and period properties where heritage bars can replicate the authentic look of classic timber windows. With low-maintenance uPVC construction, A+ energy ratings, and high-security mechanisms, these windows are perfect for homeowners across Newcastle and the North East who want to enhance their property’s style, efficiency, and durability without the upkeep demands of traditional timber.
Why Omnia Flush
Considerable care has been taken to capture the charm and elegance of a traditional timber window, even down to the tactile woodgrain finish, but combined with the advanced low maintenance qualities associated with modern day uPVC windows. Your Omnia Flush Windows benefit from exceptional thermal performance (U-values as low as 0.8 W/m²K with triple glazing), superior acoustic insulation, and augmented weather protection through double-rebated frames, ensuring durability and long-term performance.
Our bespoke windows are completely tailored to your exact requirements and are all fully made to measure. We offer a combination of high security with secure closing mechanisms, low maintenance, A+ energy rated windows. Visit our showroom or contact us for a free quote.
Compliance & Safety
On our Omnia Flush range, we offer a choice of welded finish or mechanical butt joint finish. Engineered using traditional joinery techniques, the butt joint finish offers milled edges to provide the ultimate timber effect window, ensuring safety, security, and reliable operation for years to come.
