FIELD: construction. ^ SUBSTANCE: invention relates to construction engineering, namely to heat-insulating materials used for roofing and constructing protection and decorative frontal elements of buildings and structures. The heat-insulating package consists, mainly of carrying framework, external and internal lining, heat-insulating layer and vapour barrier. The carrying framework is made from asbestos cement and heat-insulating layer is manufactured from expanded plastics of carrying framework walls thickness is 3-20 mm and expanded plastic layer thickness is 5-100 mm and vapour barrier thickness is 0.05-3 mm made from aluminium sheet. All package layers are rigidly interconnected. ^ EFFECT: improved heat insulating properties of package. ^ 9 cl, 3 dwg |
