<\/div><\/div>[vc_row_inner content_placement=”middle”][vc_column_inner width=”2\/3″][vc_column_text]<\/p>\n
Metallic structures in chemical, petrochemical and power generating plants, among others, are likely to suffer fires generally caused by hydrocarbons.<\/p>\n
Tecwool\u00ae<\/sup> 825<\/strong> has been tested pursuant to standard UNE ENV 13381-4, and subjected to UL 1709 temperature curve, to determine its contribution to fire protection when applied to steel structural elements: beams, pillars or tension members.<\/p>\n
Tecwool\u00ae<\/sup> 825<\/strong> has been designed and tested to cover a great variety of steel profiles characterised by their section factor. Likewise, it is tested for several design temperatures specified in the standard.<\/p>\n

Application<\/h2>
<\/div><\/div>[vc_column_text]<\/p>\n
Tecwool\u00ae<\/sup> 825<\/strong> is spread with a pneumatic machine pursuant to the following technical specifications:<\/p>\n
A wire mesh should be fastened to the support with electro-welded nails or the like, before applying mortar.<\/p>\n
The surface to be protected should be free from dust, oil, waste, poorly attached particles, paint leftover, etc.<\/p>\n
It is recommended to use water with the application hose to wash dirt away from the faces. This will also help achieve a thermal balance between the mortar and the applied surface.<\/p>\n
In structures prone to bumps, a wooden mortar formwork could be installed.
\nDuring the spreading, mortar is pressed with a roller in order to render Tecwool\u00ae<\/sup> 825<\/strong> highly robust.<\/p>\n
