What this work involves
Review proportions, sightlines, operation and maintenance. Coordinate frames and glazing with insulation, internal finishes and existing sills. Changing an opening can require structural work.
- Frame material and profile
- Glazing, ventilation and shading
- Arrangement and opening direction
- Weather and airtight connections
- Internal and external repairs
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Include shelter, opening elements and shading in the glazing decision.
What the drawing needs to explain
Draw sightlines from two seats and show shading positions. Review the same layout in daylight and with interior lights on; privacy works differently in those situations.
Allow for later maintenance
Keep controls and glazing accessible with the final furniture arrangement. Store glazing and shading instructions together, including any restrictions on cleaning products.
Which trade-off matters?
More glazing does not automatically make a better room. Compare continuous glass with a combination of glazed and solid wall areas so views, furniture and shelter each have a place.
Cost factors for this service
Dimensions, glazing, material, fittings and installation influence the budget.
Bring this to the discussion
Photographs, approximate measurements and preferences for material and operation.
Questions about the work
Is finishing around the frame included?
