Cortizo Cor Vision Sliding Doors Cost UK: 2026 Price Guide

Cortizo Cor Vision Sliding is one of the most widely specified sliding door systems on premium UK extensions in 2026, favoured for its 20mm interlock sightline, 3-metre plus panel heights and PAS 24 certified security on minimal frames. The downside is that Cortizo sits at the top of the market on price, and most published cost guides either quote old numbers or dodge the question entirely.

This guide lays out real 2026 UK prices for Cor Vision Sliding and Cor Vision Plus Sliding installations based on current quotes we write from our Uxbridge base. All figures are installed, FENSA registered and include a 10-year CPA insurance-backed guarantee.

What Is Cortizo Cor Vision Sliding?

Cortizo is a Spanish aluminium systems manufacturer. Cor Vision Sliding is their lift-and-slide minimal-frame residential range. The key product variants are:

• Cor Vision Sliding, the core system, interlock sightline 34mm, maximum panel height 3m, double or triple glazed
• Cor Vision Plus Sliding, upgraded version, interlock sightline 20mm, maximum panel height 3.5m, improved thermal performance

Cor Vision Plus Sliding is the specification that most installers lead with on premium residential work in 2026 because the 20mm interlock gives the cleanest contemporary look at a panel height that suits typical extension ceiling heights.

For a detailed review of how the system performs see our Cortizo sliding doors review.

Cortizo's structural corner detail (no corner post, two sheets of glass meeting at 90 degrees with a shadow gap) is one of the showpiece details that justifies the system premium over cheaper brands.

What Drives Cost the Most

Three factors move Cortizo Cor Vision Sliding pricing significantly within the ranges above.

1. Panel size, not panel count

Doubling the panel count raises the cost by roughly 30 to 40%. Doubling the panel size raises the cost by 60 to 80% because larger glass units have to be laminated for safety, craned into position and fitted with heavier-duty rollers and tracks. A 3.5m tall panel requires a different engineering solution from a 2.1m panel.

2. Glass specification

• Standard double glazing (Low-E, argon, warm-edge): baseline
• Triple glazing: adds 15 to 25%, rarely specified on sliding because panels get very heavy
• Solar control glass: adds 8 to 12%, common on south and west elevations
• Laminated safety glass (both panes): adds 10 to 15%, often required for wide or tall panels
• Acoustic laminated glass: adds 15 to 25%, specified on urban or roadside properties
• Self-cleaning outer pane: adds 5 to 8%

3. Finish

• Any standard RAL colour powder-coat, single-sided: baseline
• Dual-colour (different inside vs outside): adds 5 to 10%, very common specification
• Anodised finish: adds 10 to 18%, rarely needed for residential
• Matt or structured texture finish: adds 5 to 8%

Anthracite grey (RAL 7016) is the most popular colour and adds nothing over the baseline because it's the manufacturer's default.

Extras That Get Added to Quotes

These are the costs most homeowners don't budget for until they see a detailed quote.

• Structural steel goal post to support the opening above the doors: £1,500 to £4,500, installed by your builder not Vitrum
• Threshold and flooring finishing: £300 to £800, depends on floor make-up
• Making good plaster and paint after fitting: £400 to £1,200
• Electric operation motor (lift-and-slide): £2,500 to £4,500 per panel motorised
• Integrated blinds between glass: £800 to £1,500 per panel
• Flyscreen for open operation: £450 to £900 per panel
• Track recessing into floor slab: £600 to £1,200 if drainage channel retrofitted

The "price per metre" shortcut other sites use is misleading because extras frequently add 10 to 25% to the base quote. Always ask for an itemised schedule.

How Cortizo Compares to Other Premium Sliders

Like-for-like 4m wide x 2.4m tall, 3-panel, double glazed, installed 2026 UK prices:

• Cortizo Cor Vision Plus Sliding: £16,500 to £22,500
• Schuco ASS 77 PD Panorama: £17,500 to £24,000
• Reynaers Hi-Finity: £19,500 to £28,000 (the premium benchmark, thinner sightlines still)
• Smart Visoglide Plus: £11,500 to £16,500 (mid-premium, wider sightlines)
• Origin OS-77 sliding: £12,500 to £17,500
• Sieger Legacy: £21,000 to £29,500

Cortizo sits just below Schuco and Reynaers on price while matching them on sightlines and certification. For most premium residential budgets it offers the best value in the top tier. See our Cortizo vs Schuco comparison for the detailed system-level comparison.

What You Should and Shouldn't Expect

You should expect:

• Itemised quote showing manufacture, delivery, install, FENSA, IBG and VAT separately
• Written specification naming Cor Vision Sliding or Cor Vision Plus Sliding (not just "Cortizo sliding door")
• Drawings showing panel configuration, track type, colour and threshold
• PAS 24 certification stated in writing
• 10-year insurance-backed guarantee paperwork on completion
• 8 to 12 week lead time from order to fitting

You should not expect:

• A written quote under £8,000 for any Cor Vision Sliding installation (anything that cheap is a cheaper system being sold as Cortizo)
• Installation under 2 days (a 3-panel install is typically 2 to 3 days; larger sets take 3 to 5)
• Ready-to-buy showroom stock (every Cortizo door is made to order)
• Price match with budget sliding brands (system costs are fundamentally higher)

Lead Times and Project Planning

Realistic Cortizo Cor Vision Sliding project timeline:

• Week 0: survey and quote
• Week 1 to 2: specification finalised, deposit paid
• Week 2 to 10: manufacturing in Spain (Cortizo's Padron factory) and shipping to UK
• Week 10 to 12: installation, typically 2 to 4 days on site
• Week 12: FENSA certificate and IBG paperwork by post

Plan builder's work to complete the opening (structural steel, lintels, floor slab, DPC) at least 2 weeks before the fit date. Fitting teams need a clean, square, level, weatherproofed aperture.

Is Cortizo Cor Vision Sliding Worth It?

Cortizo is a premium product at a premium price. It is worth it if:

• The view through the closed doors matters to you, every day, for the next 20 to 40 years
• You are building or extending a property where cheap sliding doors would visibly undersell the architecture
• You want the lowest lifetime cost via a 25-year powder-coat guarantee and minimal mechanical wear
• You want the slimmest sightlines without stepping up to Reynaers money

It is probably not worth the premium if:

• The sliding doors will be in a utility space, garage conversion or budget-driven rental
• You plan to sell within 5 years (you will not recover the premium fully at resale)
• You want a 4m opening under £12,000 (specify Origin or Smart instead, same good quality, thicker sightlines)

Frequently Asked Questions

How much does a 3m Cortizo Cor Vision sliding door cost installed?

A 2-panel 3m wide Cortizo Cor Vision sliding door typically costs between £11,000 and £15,500 installed in the UK in 2026. The range depends on panel height, glass specification and finish. Standard double glazing in anthracite grey at 2.1m tall is at the lower end, triple glazing or taller panels push toward the upper end.

What's the difference between Cor Vision Sliding and Cor Vision Plus Sliding?

Cor Vision Plus Sliding is the upgraded system with a 20mm interlock sightline (versus 34mm on standard Cor Vision Sliding), taller maximum panel height (3.5m versus 3m) and improved thermal performance. Cor Vision Plus Sliding costs 10 to 15% more than standard Cor Vision Sliding at like-for-like size and is the specification most premium residential jobs lead with in 2026.

Is Cortizo Cor Vision Sliding worth the extra versus Smart or Origin sliding?

If the view through the closed doors matters and you'll live with them for 20+ years, yes. Cortizo gives a 20 to 34mm sightline versus 50 to 80mm on Smart or Origin, a 25-year powder-coat finish guarantee and a noticeably heavier track that won't rattle or drift out of alignment over time. If you can't see the sightline difference from your typical viewing angle, Smart or Origin at 70% of the price is a reasonable alternative.

How long does a Cortizo Cor Vision Sliding installation take?

Manufacturing takes 8 to 10 weeks from order to delivery because panels are made to order in Cortizo's Padron factory in Spain. On-site installation typically takes 2 to 4 days for a standard 2 or 3-panel set and 3 to 5 days for larger corner or 4-panel configurations. Plan your builder's work to complete the aperture at least 2 weeks before the scheduled fit date.

Does Cortizo Cor Vision Sliding achieve PAS 24 for Approved Document Q?

Yes. Cor Vision Sliding and Cor Vision Plus Sliding both hold PAS 24:2022 certification when specified with the correct locking package and laminated safety glass. The certificate is issued per installation and covers Approved Document Q requirements for new-build and many replacement installations.

Can Cortizo Cor Vision Sliding be specified with a flush threshold?

Yes. Cortizo offer a low-threshold option for accessibility (no step) and a standard raised threshold (15 to 25mm step) for best weather resistance. For UK climate we usually recommend the raised threshold except where accessibility requirements dictate otherwise. The low threshold needs careful drainage detailing to avoid water ingress during heavy rain.

What colours can Cortizo Cor Vision Sliding be powder-coated in?

Any standard RAL colour, matt or gloss, single or dual-colour (different inside vs outside). Anthracite grey (RAL 7016) is the most popular residential specification. Matt black (RAL 9005), dark grey (RAL 7021) and white (RAL 9016) are also common. Specialist colours and anodised finishes are available at additional cost. All finishes carry Cortizo's 25-year powder-coat guarantee.
