Installation and selection of the steel structure, glass wool products

Summary: * keep the tension of glass wool blanket in rolls, 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 wool 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.

Glass wool insulation in construction

Countries in building a large number of new building materials and glass wool. Solid brick has been generally hollow blocks and perforated bricks replaced by hollow block wall, in order to improve the insulation performance of the wall, cut off the hollow channel in the block between airflow, but also to fill in each gap plus expansion of perlite, glass wool bulk or bulk mineral wool loose fill thermal insulation glass wool.
In the building envelope, whether it is commercial building or civil construction, a lightweight and efficient glass wool, rock wool, foam, glass wool. Wall insulation There are basically three forms: thermal insulation, thermal insulation and sandwich insulation. The basic old outermost layer of the wall structure of the residential building for the quality of the wall panels of wood or plastic, then a layer of rigid foam, which is the wall of the standard main break, wood frame structure. In addition, the structure of a typical wall in hollow block or hollow masonry good wall cavity filled with dense, and also can play the role of good insulation.

Of glass wool on the roof

Foreign civil roof spire more generally, are equipped with channels for air circulation in the steeple of the attic space immediately below the roof, not only solve the flow of air, can play a certain role in thermal insulation.
Above the ceiling, are generally required the laying of glass wool or mineral wool carpet, pad, or blown loose cotton insulation directly in this space, and some direct lifting the glass from cotton, or rock wool, glass wool and decorative veneer composite from the ceiling.

Applications in the glass wool on the ground

Abroad, most of the construction of the floor room and underground space, living and activity space on the floor is not directly exposed to the external environment in which the insulation of the living space to create a strong Basements and underground space is not heating space, in particular, (Source: Paul Wimbledon) in the winter, there will be quite a lot of heat came through the first floor of the floor. Therefore, in the first floor below the floor of the building, still need to fill the high-density glass wool in the basement's concrete floor and foundation soil between the laying of a certain thickness of the rigid and semi-rigid glass wool.

Selection and Application of the fire wall insulation materials

Wall insulation materials in the construction of buildings public and eliminate [2011] 65 document requirements, requires the use of the combustion performance of Class A insulation board materials. External wall insulation material the use of composite phenolic foam board, cement foam insulation board, rock wool cement composites, the external walls of rock wool board, several major product of the external walls of glass wool board is currently able to meet the state No. 65 documentation requirements. Of these products, construction methods and extruded sheet, polystyrene board, etc. is the same construction process.
1, and enhance the network of choice:
Glass fiber mesh cloth as the key to crack the protection of soft pay into the enhanced material exterior wall insulation technology for rapid development, on the one hand, it can effectively increase the tensile strength of the protective layer, on the other hand because of their effectiveness dispersed stress, the original models can produce cracks dispersed into many smaller cracks to form the crack resistance. Outside the protection of the insulation layer cracking mortar is alkaline resistant fiberglass mesh long-term alkali resistance against the crack of decisive importance. On the analysis of the durability, high alkali-resistant fiber mesh cloth than the alkali-free mesh and mesh alkali durability is much better able to meet at least 25 years of use requirements, therefore, the choice of the enhanced network , it is recommended that the use of high alkali-resistant mesh cloth.
2, the protective layer material selection:
Cement mortar of high strength, shrinkage, deformation is not enough flexibility, a direct role in the outside of the insulation layer, weather resistance, which leads to cracking. To solve this problem using a dedicated cracking mortar supported by the enhanced network, and add the right amount of fiber in the mortar, cracking mortar creased less than 3. Such as outside facing brick in cement mortar cracking can also add a steel wire mesh light, the pitch of steel wire mesh should not be too small, and should not be too short edge of the tile should cover at least two Internet hole. steel mesh should be used to the anticorrosive good hot dip galvanized steel mesh.
3, no cavity constructed to improve the stability of the system: using the design of the insulation board to do fire, the insulation layer to withstand gravity and wind pressure due to the limitations of the fire wall board insulation strength, the insulation layer cracking, or even fall off . In order to improve the strength of the insulation board should be to maximize the bonding area, with no cavity, in order to meet the requirements of the destruction by wind pressure.

Rockwool sound insulation

With high mechanical strength, the high-strength mineral wool broad is suitable for exterior thermal insulation of building -- roof and exterior wall, the production of color-steel sandwich board and other occasions where high mechanical strength is required.
