Why it is on the shortlist
Cortizo panoramic glazing and hidden-sash aluminium
Good for panoramic rear elevations, hidden-sash windows and projects where the amount of visible glass leads the design.
A brand can cover several systems with different frame depths, opening limits and thermal results. We start with the building and opening, then choose the named product rather than quoting a generic “premium aluminium” tier.
- System named on the written quote
- Glass and opening arrangement shown clearly
- Colour, hardware and threshold agreed before order
- Survey, fitting and making good itemised

Cortizo FAQs
Questions
Common questions before you compare Cortizo on a written quote.
Cortizo questions before you compare quotes.
01Can you price Cortizo from drawings?
Yes. Send elevations or rough opening sizes. Final manufacture follows a site survey and approved drawings.
02Are the published thermal figures guaranteed for my opening?
No. They are manufacturer reference values “as low as” the figure shown. Size, glass, opening lights and frame-to-glass ratio change the finished result.
03Can windows and doors match?
Often, but the systems may use different sections. We confirm the available colour, sheen and junction details rather than assuming a perfect match from a colour name.
04What does the fitted price include?
The approved scope covers supply of the named Cortizo system, standard survey, installation, making good and certification where applicable. Structural work, unusual access and final decoration are quoted separately once surveyed.
