Vapor barrier protective measures and heaters use the same as in the previously described design. In the considered design, individual deficiencies of the previous one were eliminated: the need for cutting sheets and welding stripes to steel runs; All elements of steel structures are available for inspection and painting; The risk of condensation on the runs of water vapor consisting in the air of the enclosed room; the degree of fire resistance of the structure is increased compared to the second option in the previous example. The design under consideration was used in 1949. on the construction of some objects of the metallurgical industry of the East and South (see. Part Fourth Book).Despite significant improvements, the design under consideration is not free from some disadvantages. So, styling, slab or roller heater is associated with difficulties caused by the unreasonable location of the bars of the crate with a width or length of insulation. As a result of this, when a coating device, it becomes necessary to cut plates or rolling rolls, which entails the receipt of waste and trimmings; The number of joints in the insulation also increases. If you make repairs in your apartment, it is better to contact professionals here to replace windows: installing windows PVC. An additional disadvantage of the structure is an insufficiently uniform distribution of a layer of insulation, interrupted by the bars of the crate. Some inconvenience can also imagine the difference in the level of the bars of the crate at the place of their joint. The second version of the design under consideration differs from the first replacement of short wooden bars pre-attached to asbestos-cement, with wooden bars, which serve to attach to them later (on installation) crate from bars of normal length (3-5 m). This solution avoids the deficiencies noted in the first version.
