Type 85 operable partition
Type 85 is built for taller conference rooms and banquet spaces, with higher catalog acoustic ratings and heavier core options than Type 65.
Where this series is used
In the July 2024 Dayin catalog, Type 80 and Type 85 are presented on a single product spread, with one specification table for the series. This page is published as Type 85, which is the series we offer from that spread. The standard melamine panel in the table is 80 mm thick; hard-wrapped builds are 80–110 mm and soft-wrapped builds are 110 mm. Recommended partition height is 2 to 6 metres. Sound ratings in the specification table run from 36 dB (melamine) to 42 dB (soft wrap). Vertical joints use a magnetic-strip interlock, and U-type or L-type pass doors can be fitted.

Specification table
Models, as printed in the catalog
Figures below are taken from the July 2024 specification table. Width is the panel width. Height is the table range in millimetres. Sound insulation is the catalog figure in dB.
| Model | Thickness (mm) | Width (mm) | Height (mm) | Sound (dB) | Seal travel (mm) | Face | Weight (kg/m²) |
|---|---|---|---|---|---|---|---|
| 80xcds | 80 | 600–1,220 | 2,000–6,000 | 36 | 22.5 | Melamine | 28 |
| 80xcdy | 80–110 | 600–1,220 | 2,000–6,000 | 36–40 | 22.5 | Hard wrap | 28–32 |
| 80xcdr | 110 | 600–1,220 | 2,000–6,000 | 42 | 22.5 | Soft wrap | 35 |
Track load and other catalog notes
The product spread that covers Type 80 and Type 85 uses the same load wording as the smaller series: a maximum track load of 225 kg per panel. The components table at the back of the catalog disagrees, and lists 450 kg per metre for Type 80 and 525 kg per metre for Type 85. This page foregrounds the Type 85 figure of 525 kg per metre, and still shows the 225 kg per panel wording because both statements are printed. We do not silently average or “correct” these figures. Confirm the required track capacity against your opening, panel weight, and stacking layout at quotation stage.
Construction
Base layers listed for this series
The catalog quotes a sound-insulation coefficient (RW) and a density for each base-layer option. Densities are printed in kg/m², and are shown here as listed.
| Base layer | RW | Listed density |
|---|---|---|
| Color steel | RW 50 dB | 40 kg/m² |
| Medium-density fiberboard or plywood | RW 40 dB | 32 kg/m² |
| Glass-magnesium board | RW 35 dB | 33 kg/m² |
Panels can be built as a single leaf or as a double-leaf arrangement, and can take a U-type or L-type pass door so the room remains accessible after the wall is closed.

Faces and finishes
Every series is offered in the three faces used in the catalog. The model suffix tells you which face you are looking at.
- Melamine (catalog suffix xcds). A factory-laminated decorative face. The components pages list black walnut, white oak, and sapele among the standard woods, with other colours available to the project. Melamine is the usual choice when the wall should match a typical interior door or wall finish and needs to be easy to clean.
- Hard wrap (catalog suffix xcdy). Fabric or leather applied over a firm substrate. The face is taut rather than padded, and is often specified in hotels and boardrooms that want a tailored textile or leather look. In each series the hard-wrap build is also the mid-range acoustic option.
- Soft wrap (catalog suffix xcdr). A padded fabric or leather face. It is the most tactile of the three finishes and, in every series, the catalog’s highest acoustic build, with the thickest panel and the highest listed weight.
Custom artwork, moulded faces, and two-tone builds appear in the project photographs and can be discussed with the quotation.
