Paint grade blocks are available for walling to receive a decorative finish.

SIZES & STRENGTHS
The Donlite is a solid block with plain ends, a working face size of 440mm x 215mm, and in thickness’ of 100mm,140mm,190mm or 215mm. Dimensional tolerances comply with the requirements of BS EN 771-3 Strengths are 3.6n, 4.2n, 7.3n and 10.4n.

FOUNDATION BLOCKS
The Donlite 7.3n foundation block, which is manufactured with useful finger-grips has been proven to be both efficient and economical. Size: 300mm x 275mm x 140mm.

DENSITY
The approx. density of the Donlite range is 1350 – 1450 Kg/m3

SUSPENDED FLOORS

SOUND INSULATION
The full range of Donlite blocks offer excellent sound insulation which satisfies the building regulations for both party walls and flanking walls.

THERMAL PROPERTIES
The Thermal Resistance (r value) for 100mm 3.6n blocks is 0.25m2K/W and for 100mm 7.3n blocks is 0.21m2K/w The Thermal Conductivity (k value) for 100mm 3.6n blocks is 0.40W/mK and for 100mm 7.3n blocks is 0.48W/mK.

FIRE RESISTANCE
Donlite blocks are manufactured from selected Class 1 non-combustable aggregates and will withstand fire for between 2 and 6 hours, dependant on thickness.

QUALITY CONTROL
The Donlite aggregate block is manufactured to comply with BS EN 771-3 Our process involves checks and tests providing continuous quality control from raw materials to finished product.
