glassine

Faced with the choice of roofing material is taken into account a number of factors such as the weight of the material, technical parameters, atmospheric impact, durability and others. Among the fundamental criteria is the price side of the issue.The most low cost and accessible methods of arrangement of roofing systems are rolled materials, whose use does not require special skills and tools.

Modern roofing system is constructed on the principle of "pie", that is, the roof isfrom several layers each of which performs its technical function.One of these layers is the asphalt (though the roof is not the only area of ​​its application).What are the technical characteristics of the glassine, features and shortcomings of this material?It is in our article with photos and video materials.

Scope

To start, determine what is asphalt?Glassine - cardboard, which is at the stage of production is handled with special solutions on the basis of bitumen.

Today, the scope of the glassine means:

• use to provide a vapor barrier - for example, in the regeneration of garages and utility extensions;
• on pipework and heating mains;
• processing concrete rings, requiring additional finishing and treatment of septic tanks;
• temporary packing small items;
• used as a temporary coating;
• saving insulation from moisture;
• when using soft asphalt roofing performs the function of the substrate;
• wood surface asphalt roofing allows you to "breathe";
• metal surface asphalt protects against corrosion.

Specifications glassine

Today, the building material is available in several brands such as P-250, P-300, and asphalt roofing grade P-350.The higher the score, the greater the strength and properties of glassine, and so worthy of its technical characteristics.

• Glassine P-250 - strength in tension of 15 kg, on the surface of a material such marks no water for 10 hours.
• Glassine P-300 - tensile strength - 22 kg, the water does not appear within 20 hours.
• Glassine P-350 - this brand is used in the roofing system, the level of water absorption is 20% by weight, the strength in tension - 22 kgs, glassine keeps its technical features to +5 degrees, at a lower mark on it appear cracked.

Benefits

should be carefully for the correct choice to read some of the benefits of glassine:

• The most basic advantage of glassine is the cost of the material, the higher the grade, the more expensive fabric.
• versatile material - installation is so simple that its installation is important to have professional skills.There are several mounting options, it all depends on the base material - fixing brackets, bonding and building adhesive tape.
• Low weight allows installation without additional settlement systems, and works as a strengthening of the foundation, roofing system.
• Maintainability - the canvas is replaced quickly and do not necessarily have the skills.
• Tenacity.
• moderate water absorption.

Disadvantages

to compile a correct evaluation is important to read and glassine disadvantages:

• If the installation is on a damp surface, the reliability of the material is sharply reduced.
• work is not recommended at low temperatures, as it breaks down at temperatures below zero.
• Ultraviolet rays destroy the structure of glassine paper and its installation on the exposed surfaces inappropriate.
• Fever may contribute to the evolution of harmful impurities.

It is understood that the manufacturers are positioning glassine paper as a material for vapor barriers.Using it for other purposes, should be carefully weigh the "pros" and "cons", read reviews from experienced builders.
