<p>The invention refers to sandwich structures usable in construction, specifically in building and construction shielding structures and in roofing. It is targeted at elaboration of construction sandwich panels with high insulation and sound insulation properties, high fire - resistive and waterproofing properties, at the same time reducing their weight, simplifying structures and cutting structures' cost. These panels can be widely used in construction, specifically, in roof structures. The target is attained in such a way that the upper layer of the panel's upper sheet is a waterproofing layer, i.e., liquid rubber, under it there is a cement chip layer, i.e., a woodwool board followed by carbamide foam plastic- kriterm layer and the upper layer of the bottom sheet is upper layer cement chip layer, i.e., a woodwool board, following below thickness proportions of components of the layers - liquid rubber: woodwool: kriterm: woodwool 1:(4-20):(30-60):(4-20) accordingly, at that the thickness of the liquid rubber layer is 2 mm.</p> |
