Review of the best according to the editors. About the selection criteria. The the material is subjective, is not advertising and is not serves as a guide to the purchase. Before purchase is needed consultation with a specialist.

Among the various types of insulation, the leading place is polystyrene foam. It is a foamed polymer material composed on 98% of the air. It does not exert pressure on the structure and has low thermal conductivity 0.038 W / mK. Expanded polystyrene is used in liquid and solid form. In the second case, for fixing the plates to the walls and the ceiling use various adhesives. From the quality and type of binder depends on the reliability of mounting blocks, installation time, technical and weather conditions for installation. To facilitate the selection, we prepared a rating of the best adhesives for expanded polystyrene based on product specifications and user reviews.
