LighthermDrymix_ Heading

Lightherm prepacked drymix

is a lightweight insulation screed that is suitable for many indoor and outdoor applications where lightweight properties, thermal and acoustic insulations are desired.

 

It is a convenient and ready-to-use lightweight insulation screed that is made of ultra lightweight aggregates (3 – 6mm) and cement.

 

The standard Lightherm Prepacked Drymix is made to a density of 250kg/m³. The Lightherm Prepacked Drymix has a low thermal conductivity of 0.067W/mk. It has a COC (Certificate of Conformity) issued by TÜV SÜD PSB Singapore for non-toxicity based on fumes analysis. (BS 6853: 1999 Annex B, B.1)

Lightherm & Lightherm Mini are lightweight aggregates that are specially treated with the patented VODAPRUF additive.

They are mixed with cement to yield light weight screed with a low density of 250 kg/m3 for Lightherm Screed and a higher density of 1,200 kg/m3 for Lightherm Mini Screed.

The granular size of Lightherm is 03 ~ 06mm while the granular size of the smaller Lightherm Mini is 02mm.
