Extralyte Specifications

EXTRALYTE SPECIFICATION AND TECHNICAL DATA

DESCRIPTION
A general purpose low density building block manufactured from a blend of man-made expanded clay and other quality lightweight aggregates. Suitable for a wide range of applications in load bearing and non-load bearing construction. The standard block has a textured grey face which is an ideal key for plastering, rendering and drylining and readily accepts most types of fixings. Paint grade blocks are available for walling to receive a decorative finish.

SIZES & STRENGTHS
The Extralite is a solid block with plain ends, a working face size of 440mm x 215mm, and in thickness’ of 100mm and140mm. Dimensional tolerances comply with the requirements of BS EN 771-3 Strengths are 3.6n, 4.2n, and 7.3n.

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

DENSITY
The approx. dry density of the Extralyte block range is 1050 – 1100 Kg/m3

SUSPENDED FLOORS
The 100mm 7.3n Extralyte can be used in conjunction with pre-cast concrete flooring beams and provides a safe and durable working platform.

SOUND INSULATION
The full range of Extralyte blocks offer adequate sound insulation to satisfy building regulations. Sound Reduction (RW) for 100mm Extralyte, depending on wall finish, is approx. 40dB (Mass Law).

THERMAL PROPERTIES
Thermal Conductivity (k value) for 100mm Extralyte 3.6n is 0.322W/mK Thermal Resistance (r value) for 100mm Extralyte 3.6n is 0.31m2K/W.

FIRE RESISTANCE
Extralyte blocks are manufactured from selected Class 1 Fire Resistant aggregates as defined in BS 5628 Part 3.

QUALITY CONTROL
The Extralyte 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.
