Insulated masonry units — an EPS core cast into the brick.
Kit complete
LiteCore Bricks are large factory-cast, non-load-bearing lightweight walling blocks of EPS-beaded foamed cement used as infill inside a light-steel (SANS 517) or reinforced-concrete frame; external blocks are a 150 mm composite (two 45 mm foamed-cement skins around a 60 mm CavityLite EPS core) and internal blocks are 100 mm solid foamed cement, both 1200 x 340 mm.
| Property | Value | Standard |
|---|---|---|
| Product / build-up | Non-load-bearing EPS-beaded foamed-cement infill block. External 150 mm = 45 mm foamed cement + 60 mm CavityLite EPS core + 45 mm foamed cementinternal 100 mm = solid foamed cement (no core). Tongue-and-groove, stretcher bond | Agrement 2020/609 |
| Block dimensions | 1200 (L) x 340 (H) x 150 (external) / 100 (internal) mm | Agrement 2020/609 |
| Thermal resistance (external wall, total R) | 2.30 m²K/W | Agrement 2020/609 (SANS 10400-XA) |
| Density | 400 (block); 15 (CavityLite EPS core) kg/m³ | Agrement 2020/609 |
| Mass per brick | 18 kg | — |
| Wall self-weight | 60–68 kg/m² | Technopol declared |
| Fire-resistance rating (external walls) | 120 (non-combustible, type FRR) min | SANS 10400-T |
| Acoustic performance (between rooms) | 45 (DnT,w); Rw 45–48 across panel build-ups dB | SANS 10218-1 |
| Framing / application limits | Non-load-bearing infill onlymust sit within a SANS 517 steel or SANS 10100 RC frame with cast in-situ ring beams; wall dimensional limit 3500 mm | Agrement 2020/609; SANS 517; SANS 10100 |
Thermal: 2.30 m²K/W is the certified total R-value of the plastered external wall build-up (12 mm plaster + 45 mm foamed cement + 60 mm EPS core + 45 mm foamed cement + 12 mm plaster, 174 mm overall). The datasheet also quotes R > 2.2 for the 150 mm brick alone. The bare foamed-cement thermal conductivity (λ) is not published, so no U-value per thickness can be stated. Compressive strength: the product is explicitly non-load-bearing infill; the strain and test method behind the >1.0 / <5 MPa figures are not stated. Density: factory QC 28-day dry densities measured higher than the 400–450 kg/m³ certified nominal (~493–510 kg/m³ for 150 mm blocks, ~547–597 kg/m³ for 100 mm blocks; source: LiteCore Block Densities.xlsx) — mix/grade dependent. Fire: the 120-minute rating is the SANS 10400-T deemed-to-satisfy classification for the plastered external LiteCore wall. A separate independent SANS 10177-2 test (report FT 24-003) achieved FR60 — Stability/Integrity/Insulation each 60 min — but on the NuClad LiteCore LSF assembly (Chromadek + plastered LiteCore on a light-steel frame), which is a different build-up, not the bare block wall. Do not generalise either figure to other assemblies. Acoustic: the Rw 45–48 dB figures are from mathematical modelling (Acusolv), not laboratory measurement; the 45 dB DnT,w is the Agrement-accepted between-room value.
