Start by stating briefly what the scheme involves and confirm that Kombi is required, with one fixed glazed light and one sash opening to the outside. Describe the proposed installation and add a basic window elevation. Mark clearly whether it is drawn from indoors or outdoors. With that orientation established, the arrangement, opening movement and nearby building elements can all be interpreted correctly at the first review.
Next, supply the manufacturing sizes and keep them apart from both aperture measurements and the listed profile figures. One annotated sketch can carry dimension lines, stationary light, sash, interior and exterior faces, plus viewing direction. Use metric units throughout, and label every number. Any unusual feature in the opening or neighbouring construction should be drawn clearly and also mentioned in the accompanying project description.
Specify both the timber and cladding status, choosing pine, aluminium-covered pine, oak or aluminium-covered oak. Add separate lines for the finish colour and required handle. This keeps material, visual treatment and operating detail clear. SPILKA and IPA are named suppliers of technical window hardware, not promised customer choices for the handle brand.
Record whether the insulating glass is to use 2 or 3 panes, then quote the entire designation of the chosen bar design. Compare the drawing against that designation to ensure the stationary light and sash carry the correct divisions. When their grids differ, label which bars apply to each section. Marking the viewing orientation also avoids reversing the arrangement when moving between exterior and interior elevations.
Complete the enquiry by reviewing operation, sizes, frame material, cladding, finish, insulating glass, bar design and handle. Ensure drawings are annotated and clearly distinguish the building opening, complete required unit and component-profile figures. Structured information gives us an intelligible account of the project from which to prepare the made-to-measure Kombi configuration.
