Lightherm 250 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. Lightherm is mixed with water for direct application.
The standard Lightherm Prepacked Drymix is made to a density of 250 kg/m³. The Lightherm Prepacked Drymix has a low thermal conductivity of 0.067 W/mK.

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.
Lightherm and Lighterm Mini Screed are suitable for many indoor and outdoor applications where lightweight properties, thermal and acoustic insulations are desired.
