Expanded Clay Aggregate (LECA)

This lightweight aggregate is an alternative component to the HASOPOR recycled foamed glass for the insulation layer .

It has been used for many years for this application and is still popular as it is an economic alternative to the recycled foamed glass.

HASOPOR Recycled Foamed Glass

Hasopor Recycled Foamed Glass is a superior loosefill insulating aggregate ideal for use in our LABC accredited limecrete flooring system.

Our flooring system does not include a moisture impermeable barrier (Damp Proof Membrane). The control of ingress of moisture is achieved by using a layer of Hasopor recycled foamed glass aggregate beneath the slab material. This material carries European Technical Approval (ETA no. 05/0187) and is certified to resist the wicking of moisture above a known height.

This material also has an excellent thermal resistance capability – (certified conductivity of 0.129W/mK). We calculate the thickness of this layer to provide a specified U Value, taking into account the length/thickness of
perimeter walls, overall floor area etc - see Accredited Floor Calculation Form.
