Installation and selection of the steel structure, glass wool products

Summary: * keep the tension of glass wool blanket, close the seams between the aligned volumes and volumes, longitudinal lap when the lap joints should be arranged in the purlin; wall construction * Post cotton toward the indoor side of theunwinding from the eaves to the foot of a wall, glass wool felt in rolls is fixed with double sided tape on the bottom of the purlin, stay 20 cm.
According to JBJ26-95 "Energy conservation design standard for the same region, glass cotton selection criteria are different. The low temperature region is generally used in high bulk density and high thickness. High temperature region with low bulk density and low thickness.
First, the roof construction
The laying of glass wool felt in rolls, veneer toward the indoor side of the perpendicular to the purlin to stay in the side of the roof at about 20 cm volume felt with special fixtures or double-sided tape fixed on the outermost purlin;
Unwinding ensure that right from the tension, the glass wool felt in rolls laid at the eaves of the other side, 20 cm volume felt the same stay, with special fixtures or double-sided tape fixed on the outermost purlin;
Cotton between two volumes connected by the edge of the veneer fly stapled method;
* Install roof color plate, remove the fixture of both sides of the roof at the closing edge 20 cm veneer reserved for glass wool;
* To keep the tension of glass wool felt in rolls, close the seams between the alignment, volume, and volume, vertical need lap, lap joints should be arranged in the purlin;
According to project needs in order to avoid cold bridges the generation, you can consider purlin pad rigid insulation materials, such as XPS;
Second, the wall construction
Post cotton toward the indoor side of the unwinding to the foot of a wall from the roof, glass wool felt in rolls is fixed with double sided tape on the bottom of the purlin, stay 20 cm;
Purlins in more than the top of the wall of the glass wool felt in rolls 20 cm cut off, double-sided adhesive fixed;
* Glass wool income side, the installation of color steel plate;
* Note that to maintain the tension of glass wool felt in rolls, close the seams between the aligned volumes and volumes.
