The questions on this page are only the ones you won't already find on the site's other pages: each answer points, where needed, to the page that goes deeper.
In everyday use they are almost synonyms, but technically: the "finestra" (window) is the complete element you see; "serramento" is the technical term for all the closing elements of a building (windows, French doors, doors); "infisso" strictly means the fixed frame anchored to the wall. In quotes you will often see "serramenti": it means the whole set of windows and doors in the job.
Very little: clear access to the windows and doors to be measured, keep any quotes or data sheets of the old frames if you have them, and note down the problems you notice (draughts, condensation, noise, colder rooms). If the job concerns a condominium, it helps to know whether there are rules on façade colours and materials.
At the moment: [Showroom — to confirm]. At quote stage we will tell you how to see samples of profiles, glass and finishes before deciding: it is a step we recommend, because materials and colours look much better in real life than in photos.
Yes: many families start with the coldest or noisiest rooms and complete the job later. Keep two things in mind: some deductions have conditions linked to the type of work, to be checked at the time; and materials and finishes chosen today must still be available tomorrow — we note them in the first quote, so phase two matches phase one.
