Cortizo 4700 Slider
Uninterrupted Views
Forget bulky frames—our innovative SpeedBead® glazing channel gives you an ultra-slim sightline (just 33 mm!). More glass means more natural light, more sky, more of your garden—in short, you and your space feel instantly bigger and brighter.
Effortless Operation
Heavy doesn’t have to mean hard work. Precision-engineered rollers carry up to 300 kg per panel, so even a giant four-panel door glides open with a gentle push.
Cosy Comfort All Year Round
Stay warm in winter and cool in summer. A state-of-the-art polyamide thermal break delivers U-values as low as 0.9 W/m²K—so you enjoy lower energy bills and a more comfortable home.
Weather-Wise & Secure
Built tough to keep the elements out and your peace of mind in. The system is wind- and watertight to industry-leading standards, plus multi-point locking with anti-jemmy hooks means it’s PAS 24 and Secured by Design approved.
Tailored to You
Whether you want two wide panels, a corner-opening layout, or a grand four-panel span, we’ll configure it to fit. You pick any RAL or BS colour, add anodized finishes, and choose from glazing options up to 44 mm thick for solar control, noise reduction, or extra security.
Seamless Access & Style
Internal flush thresholds create step-free transitions—perfect for prams, wheelchairs, or just that sleek, modern look. Pair with matching curtain-wall or casement frames to carry your design theme throughout the home.
Expert Back-Up
From detailed structural calculations to CE marking and BBA certification, our team supports you every step of the way. You’ll get clear installation guides and responsive after-sales care—no guesswork, just confidence that it’s done right.
