OPTIMA System - Isover

OPTIMA System – High level thermal performance for renovation
The following calculations demonstrate thermal insulation performance one can expect using the OPTIMA System with different types of
wall construction. When insulating an outer wall, VARIO KM /KM Duplex UV has to be installed as vapor retarder and airtightness layer.
In all the examples cited here, accessory OPTIMA2 Supports Reno and a standard plaster board (12.5 mm) are applied to different
types of supporting wall and insulation materials.
* Calculations were made with TRISCO software, version 10.0w ©2002 PHYSIBEL, conform with existing standards.
** Air gap of 7.5 mm; the insulation material is compressed flush to the vertical studs.
