Ultralite is a super lightweight solid aggregate block manufactured from a blend of lightweight aggregates and cement. It is very light and easy to use and provides good all round technical performance. It is available in a 100mm width.

Hemelite Ultralite working dimensions

Ultralite has a face size of 440mm long x 215mm. Block width is 100mm.

Hemelite Ultralite weights

Unit weight: 9.4kg

Laid weight including mortar: 104kg/m²

Unit and laid weights are approximate and calculated based on the specified dry density with 3% moisture content by volume added to provide equilibrium weights.

Hemelite Ultralite availability

Ultralite is currently produced at our Midlands block plants and is likely to be more competitive in the Midlands and surrounding counties, but please contact our Sales Team for prices and availability.
