Glass wool - insulation , which can cope with their own hands

first acquaintance with glass wool

latest technology used for the manufacture of glass, so it is safe.It is considered a universal heater, as its operation is possible at any temperature.Yet thanks to its sound insulation properties, the noise will be heard only where it is produced.

There are several types of wool, which are divided according to the application.Thus, the isolated insulation for pitched roofs, exterior walls, horizontal surfaces.In addition, it has a different shape: rolls, plates, mats.

• material passes steam and does not absorb moisture;
• wool is convenient to use in confined areas;
• low cost;
• has good water repellency;
• environmentally friendly material;
• easy installation;
• resistance to different temperatures;
• resistance to chemical agents.

But there are also disadvantages :

• increased brittleness of fibers;
• insulating properties slightly lower than that of mineral wool;
• low density;
• shrinks.

main condition for the selection of insulation is the thermal conductivity.It should be less than one, and, the lower it is, the better.This ratio indicates a title or on the package.

Another important criterion that should guide - it does not infest rodents, because this material is sufficiently elastic and dense, and most importantly inedible.

How to work with glass wool - secrets of successful isolation
