Start with information about the building
Record approximate window dimensions and quantities, but do not treat your own measurements as manufacturing dimensions. Part of an existing frame may be hidden behind plaster or other layers. The condition of the reveals, wall thickness and planned external insulation also matter.
Photograph the windows inside and outside and send the pictures to the person preparing the quotation. State whether you intend to retain divisions, sills and shading. Before ordering, agree a professional survey and responsibility for the measurements. This connects your initial requirements with actual installation conditions and helps confirm which window variant can be used.
Check the variant, not just the family name
The IDEAL NEO AD variant discussed here has a 76 mm installation depth, two seals and a classic non-flush sash. These facts define the profile but do not determine how the window should be positioned in an existing opening. The installation arrangement must suit the wall and refurbishment scope.
Ask for the full system name and a drawing of the divisions in the quotation. If you are also considering IDEAL NEO MD, compare windows with identical dimensions and equipment. This separates differences in profile construction from differences in glazing, colour or installation, which also affect the quoted scope.
Include the work around the window
Establish whether the price covers removal and disposal of the old windows, preparation of the opening, installation, sills and making good the reveals. Consider room protection and access to the work area. Delivering windows to an upper-floor apartment may require separate arrangements.
If refurbishment includes insulation or replacement shading, discuss the work sequence. Sills, blinds and façade layers must suit the planned window position. Ask which tasks the window supplier will carry out and which remain your responsibility. A clear division of work makes the schedule easier to agree and the quotation's completeness easier to assess.
Prepare for comparison and handover
Check glazing, hardware, colours on both sides and complete-window performance in the quotation. Explain your expectations for thermal comfort, noise and everyday operation. Do not assume that the number of seals alone determines all performance characteristics.
Agree the documents provided at handover, operating instructions and service scope. Keep the accepted schedule, drawings and installation description. Your discussion with KM Okno about IDEAL NEO AD will then cover a complete replacement project, not just a profile price. You can assess what the agreed amount includes and what additional work must be arranged before the installers arrive.
