Define the finished opening
Identify where each dimension is measured. The overall pergola footprint, space between posts and finished glass opening are different references.
Record floor levels, thresholds and beam clearances on the same drawing. A late change to the glass track can affect the required opening even when the pergola footprint stays the same.
Exchange an interface schedule
Ask the glass supplier for its actual system details, then give the pergola team one coordinated set. Use this buyer checklist to identify missing information.
| Interface | Information to exchange |
|---|---|
| Opening | Finished width and height, reference levels and required installation allowances. |
| Tracks and fixing | Track sections, fixing locations and structural inputs from the glass supplier. |
| Panel travel | Sliding or folding movement, stacking position and access clearances. |
| Floor and water | Threshold detail, floor levels, water paths and pergola discharge. |
| Responsibility | Who confirms compatibility, supplies fixings, installs and handles each service issue. |
Confirm the frame and the glass separately
The JY accessory range includes sliding and folding glass. Its accessory planning sequence coordinates openings, tracks and drainage before production.
That is evidence of a coordination process, not blanket third-party approval. When specifying a motorized louvered pergola, identify the frame and roof configuration as well as the glass package.
Approve one coordinated drawing
Follow the engineering drawing workflow: record each opening, interface and unresolved item before fabrication. Keep confirmation from the parties responsible for the glass, pergola and site work.
The window and door company guide raises this compatibility question. Here, the practical next step is the exchange of system details, not an assumption that existing window-installation experience settles the interface.
Send the glass information early
- Pergola layout and numbered enclosure openings.
- Glass-system drawings, tracks and fixing requirements.
- Finished levels, drainage and panel stacking positions.
- Supplier contacts and the proposed installation scope.
If a detail is not available, label it unresolved rather than ordering against an assumed dimension.
Questions buyers ask
Can I send the glass drawings after ordering the pergola?
That may leave interfaces unresolved after components are prepared. Send them before final configuration approval; later changes need a separate review.
Does the same nominal width mean the glass will fit?
No. Track space, installation allowances, finished levels and fixing details also matter. Compare the actual drawings.
Who provides support if the glass and pergola come from different suppliers?
Agree the split in writing before ordering. Separate product supply, interface confirmation, installation and service responsibilities; do not assume one supplier covers the entire package.
Compatibility, structural interfaces and installation conditions are project-specific. This checklist is not a glass design, fixing specification or third-party product approval.
Send both system drawings
Include the proposed glass system and a marked pergola layout for interface review.
