Quality roofing is protected from moisture using a layer of vapor barrier. A rolled material called glassine has become widespread. This inexpensive and versatile product is used in construction as a vapor and water insulator.
Several decades ago, roofing paper was used as a waterproofing material. Today it is known to have carcinogenic properties. Harmful industries are being replaced by new technologies. Glassine has found application in construction, since during its manufacture there are no harmful emissions and wastewater is not polluted.
Produce glassine on universal units, which are specially designed for rolled materials. Such machines have a continuous running of the web. Machines that produce glassine, the application and design are different. All units are combined into a mechanized production line. Their control is semi-automatic; there is an alarm and control system.
The production of a product includes the following operations:
-
Glassine application price unwind cardboard;
- gluing material;
- Impregnation in the bathroom;
- in-camera processing;
- cooling;
- winding rolls;
- product packaging.
Pergamin has found application not only in roofing. In the construction of baths and saunas, this material is also used, protecting the walls from evaporation and moisture saturation. In dachas and outbuildings, a layer of glassine is laid on the inside.
Universal material glassine also found application as a waterproofing floor. When working on heating mains, product sheets are mounted using wire, clamps and adhesive tape. Waterproofing foundations, building facades - those areas where the product is used.
Thanks to its vapor barrier properties and water resistance, glassine has found application, while its price is low. For example, if you buy a roll marked P-250, it will cost 75 rubles. P-300 glassine 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. P-350 grade has the highest density.
Product benefits:
-
Glassine Specifications high strength;
- frost resistance;
- heat resistance (thanks to such a component as bitumen);
- moisture resistance;
- durability;
- easy to use;
- flexibility;
- a little cost.
Pergamin technicalhas the following characteristics. 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 prevent the walls from getting wet. When using fibrous insulation, it is necessary to use a film. That is why glassine is so widely used. In addition, more modern products have appeared on the market, surpassing it in terms of quality characteristics. Builders use perforated and non-perforated materials.
Vapor and waterproofing is necessary, and it is carried out using roll or sheet materials.
