Why it is on the shortlist
Aluminium from one of Europe's biggest window groups, useful when aluminium and uPVC need to coordinate in one house.
Good for mixed-material homes, aluminium entrance doors and projects where matching windows and doors matters.
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

Questions
Deceuninck Decalu FAQs
Common questions before you compare Deceuninck Decalu on a written quote.
01Can you price Deceuninck Decalu 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 Deceuninck Decalu system, standard survey, installation, making good and certification where applicable. Structural work, unusual access and final decoration are quoted separately once surveyed.
