Frequently asked questions
How much do Cortizo and Schüco PVC and aluminium windows cost?
The price depends on the type, dimensions, glazing and colour. You can get an instant price range with our online simulator or request a free, no-obligation quote — we respond quickly with an exact figure for your project.
Which areas of Portugal does MultiWindows serve?
We install nationwide and are based in Mem Martins (Sintra). Our in-house team handles measurement, manufacture, installation and after-sales service.
What is the difference between PVC and aluminium windows?
PVC offers superior thermal and acoustic insulation and is maintenance-free, making it ideal for homes. Aluminium allows slimmer profiles and larger spans. We work with both materials using Cortizo and Schüco profiles and recommend the best solution for each project.
How long does window replacement take?
After precise on-site measurement, manufacturing usually takes a few weeks. Installation itself is fast: most homes are completed in 1–2 days, without invasive construction work.
Do PVC windows improve a home's energy efficiency?
Yes. Cortizo and Schüco PVC windows with double or triple glazing significantly reduce heat loss in winter and overheating in summer, lowering energy bills and improving the property's energy rating.
What warranty do MultiWindows windows have?
All our Cortizo and Schüco PVC windows and doors include the legal warranty and after-sales technical support from our in-house team, from manufacture to installation.
