Bi-fold Plus Door — Ud ≥ 0.78 W/m²K
Cortizo's slim premium bifold uses 80mm profiles with a 45mm polyamide thermal break and a 110mm reduced central junction. Whole-door U-values from 0.78 W/m²K, comfortably exceeding the current Approved Document L 1.4 W/m²K maximum and meeting the Future Homes Standard threshold for new builds.
COR Vision Sliding & COR Vision Plus Sliding
Cortizo's slim-line sliding range. COR Vision uses a 20mm central junction with max sash 2500×3000mm at 320kg. COR Vision Plus reaches a 25mm central junction with max sash 4000×4000mm at 400kg manual or 700kg motorised, accepting glazing to 54mm. The result: near-frameless panoramic glass walls at a fraction of structural-glass cost.

Frequently Asked Questions
What is Cortizo?
Cortizo is Europe's largest independent aluminium systems manufacturer, headquartered in Padrón, Spain. Founded in 1972, they produce thermally broken aluminium profiles for windows, doors, sliding doors, curtain walling and structural glazing. Cortizo systems are used in over 90 countries and specified by leading UK architects for premium residential and commercial projects.
Which Cortizo systems do you install?
We install the Cortizo aluminium range: Bi-Fold (standard bifold, 73mm frame, 120mm meeting stile, max sash 1200×3000mm), Bi-fold Plus Door (slim premium bifold, 80mm/45mm thermal break, 110mm central junction, Ud ≥ 0.78 W/m²K), COR Vision Sliding (20mm interlock, max sash 2500×3000mm), COR Vision Plus Sliding (25mm central junction, max sash 4000×4000mm at 400kg manual / 700kg motorised), 4900 Sliding HI (heavier sliding system, max sash 2200×2600mm at 240kg), COR 70 Hidden Sash (tilt-and-turn / casement with 66mm visible section), and Millennium Plus 70 / 80 Door (aluminium entrance door, Uw ≥ 0.9 W/m²K).
How energy efficient are Cortizo windows?
Cortizo's thermally broken profiles deliver excellent whole-product U-values across the residential range. The Bi-fold Plus Door reaches Ud ≥ 0.78 W/m²K. The COR 70 Hidden Sash and standard casement systems pair Class 4 air permeability (BS EN 12207, the maximum) with triple-glazed Low-E units to achieve the BFRC A++ energy rating, the top of the BFRC scale. All comfortably exceed Approved Document L (1.4 W/m²K maximum).
How does Cortizo compare to Schuco?
Both are premium aluminium systems. Cortizo's slim premium bifold (Bi-fold Plus Door) achieves Ud ≥ 0.78 W/m²K with a 110mm central junction. Cortizo COR Vision Plus Sliding reaches 4×4m sash at 400kg manual or 700kg motorised with a 25mm central junction. Schuco's distinguishing features are their AS FD 75 / 90.HI bifold and ASS 77 PD lift-and-slide ranges. For most premium UK residential projects, both deliver excellent thermal performance. System choice is typically led by aesthetics, lead time and architect specification. Full comparison: /blog/cortizo-vs-schuco.
How much do Cortizo windows and doors cost?
Final price depends on the system (casement window vs sliding door vs bifold), opening size, panel count, glazing specification and any motorisation. Every Vitrum Solutions installation includes supply, FENSA certification, waste removal and a 10-year CPA insurance-backed guarantee. Request a free no-obligation quote on 0800 861 1450.
Are Cortizo doors PAS 24 certified?
Yes. All Cortizo opening profiles (windows, doors, bifolds, sliding doors) are PAS 24:2022 certified with multi-point shootbolt locking and laminated inner glass on opening sashes. Secured by Design configurations are available — a UK police-approved spec recognised by major insurers including Hiscox, Chubb, AIG and standard high-net-worth underwriters.

Yes. Vitrum Solutions installs Cortizo across Buckinghamshire, Berkshire, Oxfordshire, Surrey, Hampshire, Hertfordshire and West London. Including Beaconsfield, Gerrards Cross, Amersham, Marlow, Windsor, Ascot, Virginia Water, Weybridge, Cobham, Esher and all surrounding premium towns.
