Wall insulation

img11 (18)Horizontal insulation of walls, previously treated with a cement layer against pressure water - 2,8 m2 of jute or roofing felt i 0,25 m2 of jute for edges on 1 m2 of insulated surface. An allowance for each additional layer with stronger insulations 1,4 m2 of tar paper or jute on 1 m2 of insulated surface. Vertical insulation of walls previously treated with cement mortar against pressure water - 2,6 m2 of tar paper or jute i 0,25 m2 of jute for edges on 1 m2 of insulated surface. An addition to each subsequent layer of felt or jute - 1,25 m2 of material per 1 m2 of insulated surface. Expansion joints: a) in the concrete bottom or in the walls of tanks sunk in the field - 0,12 m2 of asphalt roofing felt on 1 m2 of insulated surface, b) in the bottom or in the walls of the structure below the groundwater level using copper sheets - 0,8 m2 of asphalt roofing felt on 1 m2 of insulated surface. Stickers: thickness from 8 do 12 cm of clay with chaff, from peat powder, from sawdust covered with lime-gypsum mortar, on the tar layer - after 1,25 m2 of tar paper per 1 m2 stickers. The same amount of roofing felt should be used when laying a covering made of construction rubble and for insulation made of one brick layer - holes, lying flat.
