Cortizo Bi-Fold Plus :High Performance Bi-Folding Doors at Exceptional Value. At GFD Homes, we’re always looking to offer you the very best in home improvement—and we’re excited to announce our latest addition: the Cortizo Bi-Fold Plus. This high-performance aluminium bifold door doesn’t just look stunning; it outperforms almost all other bifold doors on the market. And the best part? It comes without the premium price tag you might expect.
Bigger, Brighter, Better
If you’re dreaming of opening up your space to the great outdoors, the Cortizo Bi-Fold Plus is your perfect partner. With sash sizes up to a huge 1.2 metres wide and an impressive 3 metres tall, these bifold doors let you create dramatic, expansive openings that flood your home with natural light. Normally, you’d only see sizes like these on high-end sliding doors—but we’ve brought them within easy reach for your home.

Cortizo Bi-Fold Plus :Exceptional Thermal Performance
Energy efficiency is a top priority for homeowners—and rightly so. That’s why we’ve handpicked the Cortizo Bi-Fold Plus for its outstanding thermal performance. With an impressive U-value of just 1.3 as standard, you’ll stay comfortable all year round without needing expensive triple glazing upgrades. This makes the Cortizo bifolds not only cost-effective but incredibly energy-efficient, keeping your bills down and your home cozy.

Cortizo Bi-Fold Plus Ultimate Efficiency with Triple Glazing Option
If you’re looking to take your home’s energy efficiency to the absolute next level, the Cortizo Bi-Fold Plus also offers an optional triple glazing upgrade. This achieves a remarkable U-value of just 0.8, one of the best ratings you’ll find for aluminium bifold doors. This level of thermal efficiency meets even the rigorous Passivhaus standards, making it ideal for environmentally-conscious homeowners and cutting-edge, energy-efficient new builds.
Sleek, Modern Design
One of the standout features of the Cortizo Bi-Fold Plus is its super-slim 110mm sightlines. These slim bifolds offer a clean, minimalist look that’s perfect for contemporary homes or anyone looking to create a modern aesthetic. Additionally, the doors feature a modern square sash finish, enhancing their clean, contemporary lines and making them ideal for modern architectural styles.
Cortizo Bi-Fold Plus: Seamless Low Threshold for Easy Living
Another highlight of the Cortizo Bi-Fold Plus is its optional low threshold of just 28mm. A flush threshold provides a seamless transition between your indoor and outdoor spaces, creating a stylish and practical walkthrough. Perfect for homes with an outdoor dining space
or entertaining friends and family, this low-profile design ensures convenience and enhances the aesthetic appeal of your home.

Colours and Finishes to Suit Every Home
We know how important personal style is to our customers, and that’s why the Cortizo Bi-Fold Plus is available in over 250 RAL colours. Whether you’re looking for timeless black, contemporary grey, classic white, or something more unique, we’ve got you covered. Plus, for those special projects, you can even choose from textured, anodised, or woodgrain finishes to perfectly complement your home’s character.
