As a fabricator committed to delivering more than just products, Listers has invested significant time and expertise into perfecting Omnia, ensuring it not only looks stunning but performs at the highest level.
Behind the scenes, two key figures have been instrumental in bringing Omnia to life at Lister: Andy Foulkes, Technical Manager, and Stephen Hancock, Quality Manager. With nearly 20 years of experience each at Lister, their deep knowledge, dedication, and attention to detail have been central to the success of the system. It’s their craftsmanship and commitment that truly make Omnia from Lister something special.
A True Double-Flush Design - Omnia’s authentic double-flush aesthetic delivers a sleek, symmetrical finish both internally and externally — something rarely achieved in PVC-U systems. This detail doesn’t just elevate the appearance of a property; it positions Omnia as a clear choice for homeowners seeking elegance and simplicity in equal measure.
Sustainable, Energy-Efficient Performance - Designed to meet the highest environmental and thermal standards, Omnia achieves U-values as low as 0.79 W/m²K* with 44mm triple glazing — a figure that surpasses even the most stringent building regulations. With standard windows still reaching a strong 0.88 W/m²K, Omnia provides outstanding efficiency across the board. It’s a bold step towards sustainable construction without compromise on style.
Made for Installers, Backed by Listers - With its 70mm profile, pre-inserted PCE gaskets, and versatile application across new-build and retrofit projects, Omnia has been designed with the installer in mind. But with Lister, the great product is just the beginning — we believe success lies in the full package. That’s why we offer dedicated technical support, tailored marketing materials, and fast turnaround times, ensuring you’re backed by more than just a supply chain.
Stylish Security and Lasting Durability - Performance doesn’t stop at looks or efficiency. Omnia offers double-rebated weather seals for added protection, while PAS 24 certification — with a Secured by Design upgrade option — means security is built-in, not added on. It’s strength and peace of mind, wrapped in a premium design.
Omnia Is More - With Omnia, you’re getting more than a high-spec window or door system. With Lister, you get innovation, quality craftsmanship, and unmatched support. It’s more than just supplying windows — it’s about building partnerships that last.
