Toplite Standard is extremely versatile, and can be used where just one block type is required for use in external and separating walls in houses and apartments, as well as other building types.
Toplite Standard working dimensions
Face dimensions are 440mm long x (various widths) x 215mm high.
Block widths and weights
| Block width (mm) | 75 | 90 | 100 | 125 | 140 | 150 | 190 | 200 | 215 |
| Unit weights (kg) | 4.6 | 5.5 | 6.1 | 7.7 | 8.6 | 9.2 | 11.7 | 12.3 | 13.2 |
| Laid weight (kg/m²) | 54 | 65 | 72 | 91 | 101 | 109 | 138 | 145 | 156 |
Unit and laid weights, which are given for design purposes, are approximate and calculated based on the specified dry density with a 3% moisture content by weight added to provide equilibrium weights.
Greater thicknesses are available in Toplite Foundation
Toplite Standard applications
- Outer leaf of cavity walls, clad or rendered*
- Cavity separating walls including those conforming to Robust Detail E-WM-6 and E-WM-15
- Foundation walls in soils up to Design Sulfate Class DS-3
* When used in conjunction with cavity insulation, a partial fill solution is recommended.
