DESCRIPTION
A lightweight aggregate block. Work size 140mm x 215mm x 440mm – for single leaf walls and the inner leaf of cavity wall construction. The use of a 140mm (6" block) makes it more econimical to achieve the required ‘U’ value.

LOADBEARING STRENGTH
3.5N/mm² and 7.0N/mm² minimum compressive strengths. (for additional strengths please contact sales)

THERMAL RESISTANCE
0.348W/m° C. This block meets ‘U’ values of 0.60 and 0.45 for cavity walling when combined with other materials.

DENSITY
Average dry density 1360Kg/m³ at 3% moisture 1500Kg/m³.

ACOUSTICS
Absorption coefficient range from low & high frequency 0.20 – 0.50 exposed.

FIRE RESISTANCE
Unplastered 3 hours.
Vg finish 4 hours. 

A TYPICAL METHOD OF ACHIEVING A ‘U’ VALVE FROM 0.45-0.6 W/m²°C
