Read more →Why Cortizo
Bi-fold Plus Door, the slim premium bifold
Cortizo's slim premium bifold uses an 80mm profile with a 45mm polyamide thermal break and a 110mm reduced central junction. A-rated whole-door performance, comfortably exceeding the current Approved Document L 1.4 W/m²K maximum.
Cor Vision Sliding & Cor Vision Plus Sliding
Cortizo's slim-line sliding range. Cor Vision Sliding uses a 34mm interlock; Cor Vision Plus Sliding cuts that to a 20mm central junction with max sash 3.3m × 3m at up to 500kg per panel, accepting glazing to 54mm. The result: near-frameless panoramic glass walls at a fraction of structural-glass cost.
200+ RAL Colours, Dual-Colour Available
Powder-coated in any RAL Classic colour with optional structured, matt, satin or pearlescent finish. Dual-colour means a black exterior with a white or anthracite interior, a popular spec for heritage-fronted properties with contemporary interiors.
Class 4 Air Permeability, A++ Energy Rating
Cortizo windows are tested to BS EN 12207 Class 4 (highest air-tightness rating) and Class E1500 watertightness. Combined with triple-glazed Low-E units they reach the BFRC A++ energy rating, the top of the BFRC scale.
PAS 24 Certified, Secured by Design
All Cortizo profiles are PAS 24:2022 certified with multi-point shootbolt locking and laminated inner glass on opening sashes. Secured by Design configurations available, a UK police-approved spec recognised by major insurers.

Frequently Asked Questions
What is Cortizo?
Cortizo is one of Europe's leading independent aluminium systems manufacturers, headquartered in Padrón, Galicia, Spain. 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, max sash 1.2m × 3m), Bi-fold Plus Door (slim premium bifold with 110mm reduced central junction, max sash 1.2m × 3m), Cor Vision Sliding (34mm interlock, max sash up to 3m × 2.8m at 400kg per panel), Cor Vision Plus Sliding (20mm central junction, max sash 3.3m × 3m at up to 500kg per panel), 4700 Sliding Patio and 4900 Sliding HI (heavier lift-and-slide systems for larger openings), Cor 70 Hidden Sash (tilt-and-turn / casement, 70mm frame), and Millennium Plus 70 / 80 Door (aluminium entrance door range).
Are you a Cortizo fabricator or just an installer?
Both. Vitrum Solutions fabricates Cortizo systems in our own West London workshop — we cut, machine and assemble Cortizo profiles into finished windows and doors — then survey, deliver and fit them with our own fitters. That means one point of accountability from profile to finished installation, rather than buying made-up units from a third party. FENSA registered, with a 10-year CPA insurance-backed guarantee.

How energy efficient are Cortizo windows?
Cortizo's thermally broken profiles deliver excellent whole-product U-values across the residential range. 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) features a 110mm reduced central junction. Cortizo Cor Vision Plus Sliding reaches a 20mm central junction with max sash 3.3m × 3m at up to 500kg per panel. Schuco's distinguishing features are their AS FD 75 / AS FD 90.HI bifold and ASS 77 PD Panorama 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.
