SIP panels VIRMAK

We manufacture SIP panels with various facing sheet materials: OSB-3, cement-bonded particleboard (CBPB), SML, GB-3 (Greenboard). We also use different insulation materials in SIP panel production: expanded polystyrene (EPS) or stone mineral wool slabs – ISOVER or equivalents. Accordingly, you can choose the optimal balance of cost and SIP panel properties such as sound insulation, fire resistance, bioresistance, moisture resistance, and environmental friendliness. You can also order the most affordable and popular SIP panels with OSB-3 and expanded polystyrene.
