High-quality roofs are protected from moisture using a vapor barrier. Widespread roll material called glassine. This inexpensive and versatile product is used in construction as a vapor and waterproofing device.
Several decades ago, roofing was used as a waterproofing material . Today it is known that it has carcinogenic properties. Harmful industries are being replaced by new technologies. Pergamine found application in construction, since in its manufacture there are no harmful emissions and waste water is not polluted .
They produce glassine on universal aggregates that are specifically designed for roll materials. Such machines have a continuous blade travel. Machine tools producing glassine, the application and design are different. All units are combined in a mechanized production line. Management is semi-automatic; There is an alarm and control system.
Product manufacturing includes the following operations:
- cardboard unwinding;
- gluing of material;
- impregnation in the bathroom;
- processing in the chamber;
- cooling;
- winding rolls;
- product packaging.
Pergamine found use not only in roofing. During the construction of baths and saunas, they also use this material, protecting the walls from evaporation and saturation of moisture. In summer cottages and in outbuildings, a layer of glassine is laid on the inside.
The universal material glassine also found use as a waterproofing floor. When working on heating mains, the sheets of the product are mounted using wire, clamps and adhesive tape. Waterproofing foundations, building facades - those areas where the product is used.
Due to the vapor barrier qualities and water resistance, he found the use of glassine, and at the same time he has a low price. For example, if you buy a roll marked P-250, it will cost 75 rubles. P-300 glassine pergamin costs 167 rubles, and a roll of P-350 material costs 181 rubles. Despite the fact that the most inexpensive of them - P-250 has a fairly low density, it provides a long service life of the roof. The highest density indicator of the brand P-350.
Product Advantages:
- high strength;
- frost resistance;
- heat resistance (due to such a component as bitumen);
- moisture resistance;
- durability;
- simplicity in work;
- flexibility;
- low cost.
Pergamine technical specifications has the following. For 10 minutes it can withstand water pressure. During this time, its water absorption should be no more than 20%. Breaking load withstands 270 N.
During construction, they always use a whole range of measures that do not allow the walls to get wet. Using fibrous insulation, it is necessary to use a film. That is why glassine finds such widespread use. In addition to this product, more modern ones appeared on the market, surpassing it in quality characteristics. Builders use perforated and non-perforated materials.
Steam and waterproofing is necessary, but they are carried out using rolled or sheet materials.
