PANEL FOR ADDITIONAL WALL HEAT INSULATION Russian patent published in 2004 - IPC

FIELD: building units, particularly panels secured to inner building surface to provide additional heat insulation and to outer building surface to protect building against adverse atmospheric conditions.

SUBSTANCE: panel comprises sheets forming front and rear panel parts and defining air gap in-between. Structure panel members are formed of non-combustible materials and have low heat conductivity. Rear panel side is particularly made of polyurethane plastic foam, partitions are created of rigid polyurethane foam with closed cells, front side is made of expanded polystyrene, fiber board and gypsum board. Partitions maintain constant air gap between sheets and provide repeatedly assembling and disassembling the whole panel or front part thereof. Each partition is formed as at least four cells connected in single structure unit and having channel for fastening member insertion made in area of stiffening ribs connection. Fastening member is used for front panel part connection to partition. Stiffening ribs are embedded in plastic material of rear panel part before hardening thereof. As a result each partition is fixedly secured to rear panel part which in turn may be connected to wall with the use of fastening members.

EFFECT: reduced heat losses.
