The Future of Fenestration Materials Is Here.
There’s no secret behind what makes our windows and doors exceptional, but not everyone knows the technology that sets them apart. That’s why we’re sharing one of the key reasons we chose the RAU-FIPRO profile core for our product line.
RAU-FIPRO is a proprietary fibre composite material that combines fibreglass and uPVC to create a profile with exceptional strength, durability, and performance. While each material offers distinct advantages on its own, together they form an innovative solution that minimizes the limitations of both and maximizes their benefits.
At the heart of every GENEO window profile system, RAU-FIPRO provides outstanding structural stability. This advanced composite delivers up to twice the strength of traditional uPVC or fibreglass profiles, reducing the need for steel reinforcement in standard-sized windows while making larger window configurations possible. With less metal required, windows can be up to 40% lighter, simplifying installation without compromising performance.
For homeowners and designers, this means greater design freedom. Expansive window openings and larger glass areas can be achieved without the need for bulky support structures, bringing more natural light and unobstructed views into your space.
RAU-FIPRO also enhances energy efficiency. Compared to conventional uPVC profiles, it provides up to 10% better thermal performance, helping to reduce heat loss and improve overall home comfort. The result is lower energy consumption, reduced utility costs, and a more sustainable approach to building.
Durability is another advantage. Traditional windows often rely on corner joints that can weaken over time, allowing drafts and moisture to penetrate. In contrast, RAU-FIPRO windows feature fusion-welded corners that create a stronger, more durable seal, helping to prevent leakage and extend the lifespan of the product.
The design possibilities are virtually limitless. Thanks to the versatility of RAU-FIPRO, custom shapes, sizes, and colours can be easily achieved, offering flexibility that fibreglass alone cannot match. Whether your vision is contemporary, traditional, or completely unique, RAU-FIPRO provides the freedom to bring it to life.
We proudly use RAU-FIPRO profiles in all of our windows and exterior doors because we believe our customers deserve the very best in performance, efficiency, and design.
