This is a multi-layer material produced using a special technology. The versatility of glass insulating glass allows it to be used very widely - from basement waterproofing to device soft roof.
The practice of using this material has shown its superiority over other materials three to four times. ANDUsing fiberglass as a base increases the service life of glass insulation up to 20 years.
The material is produced in rolls, which is very convenient for transportation and use on sites. The use of fiberglass and polyesters as a base gives high technical qualities to glass insulation.
According to the field of application, glass-insol is produced in two types:
- Lining - both sides of the material are protected with plastic wrap.
- Roofing - the bottom, inner layer is protected with plastic wrap. The upper, outer layer consists of a mineral powder.
Physical and mechanical indicators:
- Heat resistance -80C0.
Breaking force N / 50 mm, not less - when used in the base:
- polyester -400 N;
- glass cloth - 294 n .;
- fiberglass - 800 N;
- Binder weight kg / m. sq. −1.5.
- Freezing point of the binder - С0 minus 15.
- Weight 1 sq. M. - from 2.5 to 4.5 kg.
- Water resistance at pressures from 0.001 to 0.2 MPa - absolute impermeability.
Stekloizol has a multilayer structure:
- Bottom protective layer.
- Astringent layer.
- The foundation.
- Astringent layer.
- Outer protective layer.
The material of the layers of protection is polyethylene for the lining glass insulation, and dusting with mineral chips - for the top layer of the roofing material.
The production schematic includes a set of special equipment:
- base unwinding table;
- bitumen cookers;
- bitumen mixer;
- pumping station with heating system;
- automatic or semi-automatic line for fusing the mixture;
- cooling system;
- finished material winding table;
Modified or oxidized bitumen is fused onto the base material - fiberglass, fiberglass or polyester. Fiberglass gives the material increased rigidity, but leaves it elastic.
Consumption of bitumen mixture from two to four kilograms per square meter. Fillers, plasticizers and polymer modifiers are added to bitumen.
Fillers consist of ground minerals - dolomite, sand, clay, chalk, limestone. These three layers give the material strength and elasticity. In the manufacture of the lining material, the outer protective layers are made of a polymer film.
For the top layer of roofing glass insulation, fine or coarse-grained mineral chips are used. It protects the canvas from mechanical damage, ultraviolet radiation. Protective layers prevent the rolls from sticking together.
Types and labeling
Alphanumeric designations are used for marking glass insulation rolls. The letters indicate the material of the web and the type of protective coating.
The numbers indicate the thickness of the web in millimeters:
- HPP 3 - canvas, film, lining. Fiberglass is used as a base. The thickness of the blade is 3 mm.
- CCI - fabric, film, lining. The basis is fiberglass.
- TCH - fabric, coarse powder on the outer layer, film on the inner layer. The basis is fiberglass. Designed for waterproofing roofs.
- HKP - canvas, powder, film. The basis is fiberglass. The material is elastic and strong and durable. Used as a roof covering.
Depending on the field of application and manufacturing technology, the weight of the canvas may be different.
With an equal number of square meters -10 sq. M. the weight of one roll is:
- HPP-2 - thickness 2 mm. Roll weight −18.5 kg.
- HPP-2.5. - thickness 2.5 mm. Weight −23 kg.
- HPP-3. - thickness 3 mm. Weight - 30 kg.
- HKP-3.5. - thickness 3.5 mm. Weight -35 kg.
- HKP-4. - thickness 4 mm. Weight - 40 kg.
- CCI-2-2.5. - thickness 2-2.5 mm. Roll weight -25 kg.
- CCI-3. - thickness 3 mm. Weight -30 kg.
- TKP-3.5. - thickness 3.5 mm. Weight - 35 kg.
- TKP-4. - thickness 4 mm. Weight -40 kg.
Reliability and ease of use, affordable price have made this coating the most common in construction.
The technical indicators of this material make it possible to use it in the following works:
- Waterproofing of foundations, underground structures.
- Waterproofing of artificial reservoirs.
- Waterproofing of engineering communications of any complexity.
- In the manufacture of soft roofs.
- Installation of roof waterproofing over the existing coating.
- Creation of exploited roofing coverings.
- Roofing for roofs with slopes.
Advantages, Disadvantages, and Cost
The advantage of glass insulation over other materials of this type is provided by its properties:
- Moisture resistance - has a double waterproof coating.
- Biological resistance - not subject to decay and destruction by ultraviolet light.
- Durability - the use of polymers increases the service life of roofing and lining materials up to 30 years.
- Light weight - a roll of glass insulation weighs from 18.5 to 45 kilograms.
- High strength with low weight.
- Flexibility and elasticity - the ability to carry out work on objects with any surface profile.
- Good sound absorption.
- Low thermal conductivity.
- Can be laid on virtually any surface.
- Simple styling technique.
The disadvantages of glass insulation include:
- When carrying out outdoor work, the air temperature should be at least minus 10 degrees. At sub-zero temperatures, it is necessary to withstand the glass insulation in a warm room for 24 hours.
- The instructions prohibit work in rain and strong winds.
But the quality of the product justifies it:
- From 45 rubles to 66 rubles per 1 square meter - is based on fiberglass.
- From 37 rubles to 60 rubles per 1 square meter - based on fiberglass.
Required materials and tools:
- roller and brush;
- roofing knife;
- roofing heater or blowtorch;
- pressure roller - in the absence of a factory-made roller, you can do it yourself from a thick-walled pipe with a diameter of 20 mm;
- glass insulation in rolls;
- primer or primer;
- building mixture - for sealing potholes and large seams;
Work should be carried out in protective clothing, observing all safety precautions.
A step-by-step guide to installing glass insulation:
- Surface preparation - all garbage is removed. The area must be swept with a broom or brush. Potholes, chips, cracks are sealed with a cement-sand mixture. The protruding beads are cut off. Peeling parts of the old surface are removed.
- Primer treatment. A primer is applied to the concrete surface - with a roller or brush. A layer of bituminous mastic must be applied to the wooden surface.
- Cut the canvases. Produced on site. It is necessary to take into account the overlap along the length - up to 20 cm. The size of the overlap of the canvas is also taken into account - 10 cm. There is a special strip on the canvas.
- Laying the first layer. The first layer is the lining fabric - TPP or HPP. If the surface has a slope, it is necessary to start laying from the bottom and place the canvas along the bottom edge. The edge of the web is heated by a burner and glued to the surface. Gradually unrolling the roll and warming it up, the entire canvas is glued. At the same time, the web is rolled with a roller. Air bubbles are expelled. The next strips of canvas are overlapped to the previous one. The joints and overlaps are warmed up and rolled especially carefully. You can reinforce them with additional strips of material.
- Laying the second layer. Used glass-insulated brand HKP or TKP. It fits according to the technology of the first.
Achieving good results and the durability of the coating depends on:
- Correctly selected material.
- Strict adherence to the laying technology.
- The professional skills and conscientiousness of the performers.
