Technical characteristics of Pergamine

Technical characteristics of Pergamine Glassine - properties, application

Any materials for thermal insulation, used in modern construction, which require a protective vapor insulation coating, which is currently the role of glassine, the properties of which are incredible.

It has become an excellent replacement for such materials as only leather and roofing paper, which contains a huge concentration of carcinogenic tar. The production of glassine will eliminate harmful emissions and do not need to be recycled.

It is extremely important to use a protective roofing material when it comes to insulating a roof by means of heat-insulating material, for example, mineral wool boards, which easily absorb moisture, swell and collapse. To avoid this, the vapor barrier should be laid under the mineral wool slab, as well as above it.

What is glassine

If we talk about glassine, then this is a roofing material that is used to protect not just roofs, but also wall surfaces from moisture, wind and condensation. It is made by impregnating cardboard with bitumen with a low softening temperature of + 45 ... + 50 degrees.

The basis for such a material will be specialized roofing board, which consists of layers of wood fibers (from 20 to 40), straw, cellulose and cotton.

Technical characteristics of Pergamine It also contains non-woven materials that provide a better ability to absorb moisture. In order to achieve excellent technical characteristics of the material, its cardboard base is usually passed through a press with a pressure of 0.3 kg per square meter.

Scope of use

Having learned how glassine is made, what it is, you should consider what types of work you can't do without it.

Such a cushioning material is used as a vapor barrier layer not just when arranging the roof, but also sheathed wooden structures in places of contact with concrete or soil in order to avoid dampness and swelling of wood products. It is used in the construction of baths and saunas, if they are erected as separate buildings on the street. In this case, 2 to 3 layers of glassine should be laid around the entire perimeter of the bath, which will serve as a limiter for thermal insulation both inside and outside.

Wide area of ‚Äč‚Äčapplication - construction of multi-storey residential buildings. Glassine is used as a lower lining base in a puff "pie" for the roof, and in the basements it is rolled out on the floor, creating a side with a height of 0.

5 meters, which go onto the walls. Here it performs a waterproofing function so that closely lying groundwater does not enter the basement room.

Glassine - properties and characteristics

Several varieties of glassine can be distinguished, which differ from each other in the thickness of the cardboard used and the types of bitumen that is required for impregnation.Such indicators will even affect the cost of the material.

Review

Brand of glassine P-250

Despite the fineness of the material, it is a very durable and elastic roofing material that provides a long service life.

The advantage can be attributed to the low level of cost, and also such a material can protect the surface from moisture ingress for 11 hours. To break a material such as glassine P-250, a tensile force of at least 16 kgf is required.

Grade of glassine P-300

The material is very strong and flexible. It is able to withstand a tensile force of 21 kgf without visible deformation. It is able to retain moisture on the surface without contact for about 20-23 hours.

Grade of glassine P-350

Technical characteristics of Pergamine This is the strongest and densest of the three. The cost, although higher than that of the previous representatives, is still acceptable for buyers. The material also endures forces of 25 kgf, and then retains moisture for more than 21 hours. The denser the cardboard for glassine, the longer it is able to absorb bitumen, becoming durable and elastic, and its water-repellent qualities increase.

Its high degree of strength is due to the fact that it is used as a lower layer in the roofing device, which will not succumb to strong mechanical loads.

Glassine has one more property, namely heat resistance. With a high melting point, it can easily endure the heat in summer. Due to its elasticity, it will not be prone to cracking in winter cold.

The life of glassine is at least 10 years. It is very easy to install and can be handled by one person due to its lightness.

Such properties can be called advantages, and the final chord is its low cost, which deprives it of almost all competitors.

Conclusions

Technical characteristics Glassine from the manufacturer "TechnoNicol" is roofing. The company assures that it has brought the material to perfection, endowing it with even the best properties, as provided for in SNiPs and GOSTs. Thanks to the high quality that the manufacturer endows with glassine, and customer reviews addressed to him are only positive.

Despite the advantages, glassine is not used as a finishing material for arranging the roof, because it does not have its own protective layer, with which it can protect itself from negative effects in the environment - atmospheric precipitation, low and high temperatures, and especially from a sharp drop, from the direct rays of the sun, and also from various mechanical damages.

Studying the technical characteristics of this material, like glassine, it can be concluded that its main field of application is the performance of the vapor barrier and waterproofing protective function of the roof as a substrate.

Usually, the material is laid on an insulating material in order to protect it from vapors and moisture of condensate, and then the roofing is laid directly, whether it be slate, tiles or a metal profile. Most often it is used on pitched roofs, due to the fact that it is the most elastic, lightweight and has excellent protective qualities. Glassine is produced in rolls with a width of 1 meter, 1.025 and 1.

05 meters. Each roll weighs 15 kg (area 20 square meters), or 30 kg (area 40 square meters).
