Most often, glassine is laid under metal and metal roofing. After all, this material does not allow moisture to get on the roof, which prevents the formation of rust.

Almost all types of roofing asphalt have excellent water resistance, which is 0.01. Water absorption for this material is 20. But it should also be said that it can boast of excellent vapor barrier. But it is important to note that the rate of fire resistance of such a framework will be quite low. The product is highly flammable.

The area of ​​any roll of roofing glass mat is usually 20 square meters. m. And the mass of the product can vary considerably from 0.5 to 0.7 1 square meters. m / kg The width of each coating can be 1000, 1025, 1050 mm.

It should be said that This model of building material has excellent moisture resistance, frost resistance and elasticity.. It provides moisture protection for 10 hours. Thanks to all these important properties, asphalt p-250 can be used for almost any type of roofing.

This sample also has a high level of elasticity and strength. In addition, this material is moisture resistant. He is able to protect the roof from the harmful effects of moisture for 20 hours.

According to many consumers and specialists, the p-300 model has a particularly long service life, as well as a fairly low cost. After all, it will be affordable for almost any buyer.

Roofing glassine has a number of positive qualities.

• Affordable price. Such material has a special low cost, so it will be affordable for any person.
• Environmental Safety. Roofing asphalt is made using modern technologies, using completely processed components. Due to this, such material is absolutely safe for humans and their health.
• Frost resistance Asphalt does not crack even with sudden temperature changes.
• Flexibility. This property greatly simplifies the transportation and installation of the product.
• Low weight. This quality of roofing asphalt also facilitates installation work with the material.
• Waterproofing. A layer of glassine impregnated with special substances and solutions does not allow moisture to affect the roof surface, which prevents its destruction.
• Maintainability. In the event of a breakdown, asphalt can be easily replaced, and there is no need at all to resort to the help of a professional brigade.

But despite such a wide range of advantages, roofing asphalt has significant drawbacks:

• Installation should not be carried out at low temperatures. Although this building material is frost-resistant, it is not worth mounting it during extreme temperature changes. Otherwise, it will quickly crack and break.
• Low resistance to high temperatures. Glassine is able to withstand any low temperatures, but under the influence of intense heat, the bituminous impregnation will simply begin to melt.
• Low fire resistance. Roofing glassine is flammable. Therefore, many experts recommend treating its surface with special building compounds that prevent a possible fire.
• Do not install on wet surfaces. Despite the fact that this material is quite moisture-resistant, it can only be mounted on a completely dry surface. Otherwise, the roll may simply break.
• It is destroyed by exposure to ultraviolet rays. Roofing glassine cannot be left in open space for a long time. Otherwise, it will become brittle and begin to collapse under the action of the sun.
• Short service life. Such products will be able to serve only 5-7 years. After the expiration of this period they will have to be replaced with new ones.
• Strong smell. Often asphalt begins to emit a strong unpleasant odor. This happens because of a sharp increase in temperature. And at the same time it disappears very quickly.

Before directly laying the base, it is imperative that you carefully clean the surface of the structure. After this roll of glassine should be rolled out over the entire plane. Fix the product with a special stapler.

Place rolls best overlapped. At the same time it must be at least 15 cm. This is necessary in order to ensure the strength and reliability of the future coating. Many experts also advise further lubricate all joints between the rows with the help of building mastic.
