APPLICATION OF EPS 033 PRO LAMBDA EcO

Expanded polystyrene EPS 033 PRO LAMBDA EKO panels are used for insulation applications requiring the transfer of small mechanical loads, including:
- Insulation of walls in external thermal insulation composite systems (ETICS) (light-wet method),
- Insulation of multilayer walls with a ventilated or non-ventilated air gap,
- Insulation of framed walls with cladding,
- Insulation of ceilings from below,
- Insulation of floors between joists,
- Insulation of expansion joints.
Due to the increased heat absorption by EPS 033 PRO LAMBDA EKO polystyrene panels, it is recommended to protect both the substrate and the EPS 033 PRO LAMBDA EKO panels from sunlight before commencing the installation. To protect the polystyrene boards from direct sunlight during the insulation work, it is advisable to use nets on the scaffolding.
