Among the STOLIT polystyrene board brands, from now on there is a long-awaited item – graphite foam Stolit Black<\/strong>. Styrofoam is the most popular material for insulation. Most often, it is used to insulate walls, but it is also well suited as thermal insulation of floors, roofs, floors, and plinths. Graphite expanded polystyrene is an improved derivative of traditional white foam, that is, expanded polystyrene (referred to as EPS). In white, thermal insulation is achieved due to the fact that more than 95% of its volume consists of air voids. In graphite, the thermal insulation coefficient is improved due to graphite admixtures.<\/p>\r\n\r\n\r\n\r\n

Coefficient of thermal conductivity of graphite foam<\/strong>
\r\nThe coefficient of thermal conductivity is the most important\r\na parameter that objectively characterizes insulating materials. The lower\r\nthe value of the coefficient of thermal conductivity (\u03bb), the better the thermal insulation.\r\nThe use of graphite in the production process of black polystyrene allows\r\nto produce slabs with coefficient \u03bb – from 0.029 to 0.033 W\/(mK). In standard ones\r\nwhite sheets to achieve such thermal insulation is impossible with technological ones\r\nconsiderations, therefore, it is necessary to use thicker layers of insulation.<\/strong><\/p>\r\n\r\n\r\n\r\n

Graphite foam, insulation layer thickness<\/strong>
\r\nUsing graphite foam instead of white\r\nminimizes the insulating layer, optimizing its efficiency. And this is the biggest question\r\nstimulates the demand for it. However, in situations where the thickness of the insulation does not have such\r\nof great importance for the appearance of the building, is still used\r\nwhite foam.<\/p>\r\n\r\n\r\n\r\n

How to glue graphite foam?<\/strong>
\r\nIt happens that contractors refuse to work with graphite\r\nfoam plastic Basing his decision on the fact that this material is difficult\r\nstick. So, graphite foam is really characterized by less\r\nadhesion when using traditional adhesive mixtures. Therefore, before applying on\r\nglue plate, its surface should be treated with abrasive paper or a wire brush.\r\nAnother method of successfully gluing graphite polystyrene is to use\r\nstronger glues or designed for gluing this particular material. <\/p>\r\n\r\n\r\n\r\n

Graphite foam and sunlight<\/strong>.
This type of foam, due to its dark color, can get very hot under the influence of intense sunlight.   This leads to high internal stresses in the plates, and as a result – to deformation of the plates. Gaps form between them, and freshly glued plates can even tear off the wall. Therefore, when performing insulation work, it is necessary to protect the facade from direct sunlight, for example, use a protective   mesh on scaffolding. During transportation and storage also  protect from direct sunlight.<\/p>\r\n\r\n\r\n\r\n

“Sumish C” and “Sumish C+” TM “STOLIT”  <\/strong>ideally suitable for working with graphite foam. It is used both for gluing and for arranging a waterproof reinforcing layer in thermal insulation systems<\/p>\r\n\r\n\r\n\r\n
