Stekloizol is a modern material intended for the production of waterproofing works during construction, and is a better analogue of roofing material.
The basis of which, unlike roofing material, whose base is paper, is fiberglass or fiberglass, which increases its tensile strength, and also gives it such properties as incombustibility, and increases its service life up to 15 years in heavy operating conditions.
Stekloizol has gained wide popularity in Russian construction.
The scope of its application is also wide - from waterproofing foundations to waterproofing the roof (more and more often roofing material is replaced with glass-insol, since the angle of inclination of the roof slope is not important for it), and glass-insulated is also used for waterproofing structures under water - these are bridge supports.
There are different grades of glass insulation for different purposes of application.
Glass insulation is marked with alphanumeric digital code .
Glass insulation is made of:
The first letter in the code means the base:
The second letter in the code means what the top layer of the material is made of. It can be made of a polymer film or coarse granite dusting.
And are designated "P" polymer film and "K" coarse-grained dressing.
The third letter in the code means the lower layer of glass insulation and has the letter "P", which means a polymer film.
The numbers in the code indicate the weight of 1 square meter of material.
During the laying of glass insulation, as a rule, use two or more layers of material. This is done to increase reliability.
The bottom layer is laid from lining glass insulation of TPP or HPP brand with a double-sided polymer coating , and top layer - grades TKP or HKP with the top layer of coarse-grained dressing.
For structures experiencing heavy loads, glass-based insulation is used, since it has higher strength characteristics.
For waterproofing foundations, as well as for installing a roof with a slope of no more than 10 degrees, glass-based glass is used.
Glass insulation is a material that is sold in rolls. Roll width is 1 meter, roll length is 10-15 meters.
To overlap strips during stacking, an indent is made without top cover from one end of the roll.
Laying glass insulating material
To perform work on laying glass insulating , is required :
When buying material, you must take into account all overlaps and allowances and buy with a small margin.
For laying glass insulation you need such tool:
Before laying glass insulating material, all surfaces must be carefully prepared :
After the initial preparation has been made, proceed to coating the surface with a primer or mastic.
This provides better adhesion of glass insulation to the surface.
Coating the surface with a primer is carried out when laying glass insulation both on a concrete surface and on a wooden one.
When laying glass insulation on a wooden surface, it is necessary that the lathing be made solid.
Cutting and rolling of glass insulation is carried out on site styling.
During the rolling of glass insulation, allowances are left on both sides for the hem. The size of the allowance on one side is 20 centimeters.
Lane overlap is also taken into account. For this, a strip 10 centimeters wide is provided on the roll.
After all the material has been cut, it is folded back into separate rolls.
Laying glass insulation starts from the bottom of the roof. This is done so that the overlap is turned downward to avoid water flowing into it.
First, a lining layer of material of the HPP or TPP brand is laid. The roll is rolled out a little. The rolled part is heated using a blowtorch or a gas burner of the rolled part. Next, it is pressed and rolled with a hand roller.
After the first strip is rolled, proceed to laying the second strip of lining glass insulation, repeating all the operations and not forgetting about an overlap of 10 centimeters.
If the roof is flat, it is recommended to lay several layers of backing glass insulation with offset strips for overlap by beads.In places where it is adjacent to walls or pipelines, additional gluing with glass insulating strips is performed.
The top layer is used for roofing glass insulation of TKP or HKP brands, having granite topping. The process of laying roofing insulating glass repeats the process of laying the underlay. When heating and rolling sheets, it is necessary to monitor the formation of air bubbles and avoid their appearance.
Glass insulation is a modern material with a service life of 15 years or more. Has better strength characteristics in comparison with roofing felt.
