Everything you need to know about Cortizo COR 70 Windows

What are Cortizo COR-70 Windows?

The COR 70 is a collection of inward opening and one outward opening window suite, offfering virtually every opening option and design for residential and commercial property.

Cortizo windows are now known in the architectural and residential sectors for their styling and design.

Characteristics of Cortizo COR 70 Windows.

Profile Depth and Construction

The designation “COR 70” denotes a 70 mm deep window frame, which balances structural stability with minimal visible sightlines. This 70mm frame depth also works well when replacing dated timber, plastic or eary-generation aluminium windows with similar frame depths.

All Cortizo profiles incorporate polyamide thermal breaks, chambers within the frames, using the now well-established set up of big thermal breaks, narrower aluminium profiles to help get to low U-VAlues. It also helps Cortizo windows achieve their always contemporary architectural designs where minimalist frames or expansive glazing is often required.

Thermal Performance of Cortizo Windows

Depending on glazing specifications, COR 70 windows can achieve U-Values as low as 1.0 W/m²K when paired with suitable triple glazing. Double-glazed units often register around 1.3 W/m²K.

Cortizo is listed on the British Fenestration Rating Council Website for most of their window products. BFRC certificates provide a simple A++ to E rating for windows, considering factors like U-values, air leakage, and solar heat gain. This single score is useful for straightforward window replacements and everyday consumer comparisons, but it can be less precise for large-scale or complex builds.

U-values, on the other hand, measure how much heat passes through a material in W/m²K, making them more accurate for detailed calculations and architectural projects. By focusing strictly on thermal conductivity data, U-values allow for precise engineering, which is especially important if you need to meet strict energy performance targets.

We often mention throughout this website that Cortizo U-Values can be vague and hard to understand. Get in touch for more information and advice. Glass specifications affect the overall product U-Value and it’s here you need to be careful, that you’re being given the whole window U-Value not the lower and seemingly better glass U-Value.

Security and Compliance

The COR 70 range often incorporates multi-point locking systems and internal glazing beads, ensuring secure hardware that reduces the likelihood of forced entry. For additional assurance, certain COR 70 configurations may carry PAS 24 or Secured by Design certifications, reflecting extensive testing against forced-entry scenarios. Overall these are well-designed and made windows with reliable security.

The Cortizo COR 70 Range

The Cortizo windows range in the UAE, comprises four contemporary window solutions for residential or commercial property. Four are opening inward designs, whilst the Flush Casement and Standard Casement are designed for the UAE market and open outwards.

Do not disregard opening inwards windows. In many respects they are better designed than outward opening, give you larger opening vents and in some cases even go up to door sizes.

COR 70 Hidden Sash

The COR 70 Hidden Sash design is engineered so that the casement frame is concealed behind the outer frame, creating exceptionally slim sightlines. This window achieves impressive maximum sizes of up to 1300mm wide or 2400mm high.

With visible sections reduced to as low as 66 mm, this configuration is ideal where an unobtrusive aesthetic is paramount. The hidden drainage channels further reinforce the minimalist effect. This window can only be appreciated close-up and how minimal it looks from the outside and inside with it’s concealed hinges and invisible handle.

COR 70 Industrial TB

Renowned for its industrial-inspired framing, the COR 70 Industrial TB variant resonates with projects seeking an urban or loft-style aesthetic. Again Cortizo shines with big openign window options up to 1600mm wide or 2600mm high.

It maintains similar thermal performance levels and provides expansive glazed areas, suited to larger structural openings where a bolder visual statement is desired.

Cortizo Casement

For projects that lean toward a more conventional casement style, the COR 70 line includes flush and standard casement profiles opening out only. There’s no other casement window that goes as big as this with the slim sightlines, up to an incredible 1800mm wide or high.

These windows retain the symmetry and flush option, with slim, contemporary lines indicative of modern aluminium systems. Yet accommodate a range of architectural periods—offering a practical choice for both retrofit installations and new-build designs.

Cortizo Tilt and Turn

The Cortizo COR 70 tilt and turn window is a multifunctional solution that allows secure ventilation in the tilt position, alongside a fully inward-opening sash for cleaning or emergency egress.

Concealed hinges and hardware help maintain an elegant appearance from both interior and exterior viewpoints.
