Glass cotton basic technical rules and installation instructions
A, glass cotton blanket installation technical specification
Exterior wall thermal insulation
The placement of a face: if the product with a face, will face outwards.
The roll mat of vertical installation:
At the top of the building with two fixed device (such as heat preservation nail) fix, glass cotton lap felt along the wall will roll mat vertical, placed in the middle of the coil diameter not less than 90 mm of fixture. When the building height is not more than 40 m, a maximum distance of every two fixing device should not be more than 1.35 m.
The level of the roll mat installation:
When the building height is not more than 40 m, horizontal roll mat, intervals of 1.20 m place fixed device (such as heat preservation nail), fixtures (bar) is not less than 90 mm in diameter, then add rafters at intervals of 0.60 m to reinforcing glass wool, see illustration related construction methods. Note: when it comes to the door, window and other special location, should be properly placed more fixtures (bar) in place to ensure that glass cotton in these parts of the fixed and beautiful.
Interior wall insulation
1, according to the length of the wall height + 1 to 2 cm with wallpaper knife cut glass wool.
2, among the wall at a predetermined position put two device used in fixed glass wool.
3, stick a face, edge and edge alignment will glass wool is fixed on the wall.
4, handle the seam position, rid of spare parts and fixtures.
Roof construction
1, laying lap blanket, glass cover toward the interior side, perpendicular to the purlin, stay in side eaves of about 20 cm roll mat, using a dedicated fixture or double sided tape should be fixed on the lateral purlin.
2, put the volume to ensure alignment and tensioning, glass cotton lap blanket laid to the other side, the roof also stay a 20 cm roll mat, using a dedicated fixture or double sided tape should be fixed on the lateral purlin.
3, between two rolls of cotton by using stapler bound on cover flash method together.
4, install roofing choi steel, down from the roof of special fixture, with the reserve 20 centimeters stick a face for the glass cotton on.
5, pay attention to glass cotton lap felt tension, alignment, volume and volume between seam tightly, longitudinal need lap, lap joint should be at the row of purlin.
6, according to the needs of engineering, in order to avoid cold bridge, can consider on the purline mat some rigid insulation materials.
Wall construction
1, stick a face toward the interior side, put the volume to the foundation, from the eaves with double sided tape will be fixed at the bottom of the glass cotton purlin, stay a 20 cm.
2, at the top of the glass cotton lap felt more than wall purlin 20 centimeters its truncation, fixed with double-sided tape.
3, install the glass wool on, metope color steel plate.
4, between two rolls of cotton by using stapler bound on cover flash method together.
5, pay attention to keep the glass cotton lap tensioning, vertical alignment, and joint tightly between the volume and the volume.
Matters needing attention
* glass wool should be placed in dry ventilated place, in the process of transportation to avoid the rain.
* glass wool should be away from open flame, pay special attention to the construction site of the molten slag.
* because glass cotton base material recovery is very good, and general polypropylene material fabrics swelling is larger than the clip jin, after the installation is complete, glass cotton base material is likely to hold up of polypropylene plastic cover fabrics, which appear in the clip reinforced vertical stripes. Due to the uneven force in the construction, the density, direction and depth of stripe is also different, affect beautiful. Method to avoid this problem is the construction of hire experienced construction personnel careful construction, glass cotton tension when using special fixture.
Second, the glass wool board installation specification
1, on the floor and corresponding to the roof set the metal framework, pay attention to the framework should be perpendicular to the floor.
2, between the metal frame has been placed, 60 cm erect vertical metal frame apart.
3, in the side of the frame with plasterboard, and should be fixed on the frame.
4, in a glass cotton between the frame.
5, on the other side of the fixed plasterboard.
3, high temperature glass wool installation specification
Pin on equipment surface welding in advance, and then with wire bound at high temperature glass wool surface of equipment, when the temperature over 250 ℃ heat preservation of equipment, had better use double deck heat preservation mode, both inside and outside two layer on the surface of the glass joints should be staggered, lest produce heat loss caused by thermal bridge. When the temperature over 400 ℃ heat preservation of equipment, suggested that inner layer with a certain thickness of aluminum silicate, the outer layer with high temperature resistant glass cotton, the joint between the two layers should be staggered. Finally coated layer outside the bread, can protect the glass wool, and to achieve the requirement of the beautiful.
