The parapet that closes the terrace edge. Its cavity is uninsulated, and deliberately so: the parapet sits outside the thermal envelope, where insulation would do no work. Read without that explanation the detail looks like an omission, which is why it is stated here rather than left to inference.

Layer schedule
| Layer | Material | Thickness | λ | Function |
|---|---|---|---|---|
| 1 Monocapa render | Single-coat mineral render | 2 mm | — | Finish to the terrace face |
| 2 Aquapanel cement board | Cement-bonded board | 15 mm | — | Substrate and rigid sheathing to the terrace face |
| 3 Steel C-stud zone | Cold-formed galvanised steel | 140 mm | — | Structure No fill is called out for this zone on the section drawing. |
| 4 Placner ribbed sheet | Cold-rolled galvanised steel, Z200, 0.3 mm base sheet | 5 mm | — | Substrate and mechanical key for the sprayed layer 5 mm is the overall profiled depth including rib height, not the sheet gauge. |
| 5 INSULTERM 600, sprayed | Sprayed thermal-acoustic conglomerate | 50 mm | 0.138 W/m·K | Continuous external insulation |
| 6 Monocapa render | Single-coat mineral render | 5 mm | — | External weather finish |
| Total | 217 mm |
An em dash means the source document does not state that value; it is not a zero. Cavity-contained layers are indented — they sit inside the stud depth, so the column does not sum to the total.
Calculated performance

Where to use it
- Terrace and flat-roof perimeter upstands
- Roof edge closures where the parapet falls outside the insulated envelope
Design notes
- The cavity is uninsulated because the parapet sits outside the thermal envelope. This is a design decision, not an omission.
- Aquapanel must not be substituted with standard plasterboard on the parapet.
- Coping and roof turn-up are project-specific and are detailed per scheme.
