EXTRALYTE SPECIFICATION AND TECHNICAL DATA

DESCRIPTION

A general purpose low density building block manufactured from a blend of 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.

SIZES & STRENGTHS

The Extralyte is a solid block with plain ends, a working face size of 440mm x 215mm, and is available in thickness’ of 100mm and140mm. Dimensional tolerances comply with the requirements of BS EN 771-3 Strengths available 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: 300mm x 275mm x 140mm

DENSITY

The approx. dry density of the Extralyte block range is 1950-2100kg/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).
