The complete window
The manufacturer’s product sheet describes NEFERIA. The project window also needs to be assessed by its dimensions, glazing, hardware, colour and installation.

Frequently asked questions
What should I send for a quotation?
Tell us the Asturias municipality, number and approximate size of openings, opening style and the system you are interested in. Add photographs if you can.
Does the published figure apply to every window?
No. Manufacturer figures describe a profile or a tested configuration. Each window’s dimensions and components affect its result.
