Basic elements a sandwich panels are a basis, a heater, a gidrovetrozashchita and external facing.
The cassette profile is a base a sandwich - panels of step-by-step assembly. Depth of a cassette profile a sandwich - panels is chosen according to thickness of thermal insulation which is planned to be used in it (usually it varies from 100 to 200 mm). Thickness of thermal insulation depends on properties of material of which it is made. It is made of specially processed steel 0,7, 0,8 and 1 mm thick. The domestic cassette profile is made both from simple galvanization, and from galvanized steel with a polymeric covering, various on color scale.
As a heater various materials can be applied - usually it is mineral wool or expanded polystyrene. As facing for this construction material porcelain tile, a siding, a professional flooring with a polymeric covering etc. are used.
Sandwich - panels of step-by-step assembly are the most perspective material for construction of modern public and industrial buildings.
The roof design without additional warming in a sandwich profiles of 100 mm in depth has a heater with a general thickness of 100 mm, and 150 mm in depth — with a general thickness of 150 mm. Usually apply 2 layers of a heater on 50 mm to thickness of 100 mm or 3 layers on 50 mm for thickness of 150 mm, at the same time the break off of seams between plates of layers has to be provided. For protection of a heater against the moisture getting under a roofing covering as a result of influence of the weather phenomena, atop the sandwich profiles keeps within a hydrowind-shelter vapor-permeable membrane of TYVEK or its analogs. For elimination of "cold bridges" over a membrane on regiments a sandwich profile establish the thermodividing UPTP strip from an isobosom (var. TP) or the thermodividing strip cut from heat-insulating plates of ROCKWOOL. From above mount the hat KPSh-50 or KPSh-90 profiles. The step of hat profiles is determined by the bearing ability of roofing facing.
