Polyethylene foam heat insulator In the category Foam Polyethylene Many people are interested in knowledge and learning about many subjects, this knowledge may be vital at some point in your life, attention enough, and dive into more detail more articles and learn more information about Polyethylene foam heat insulator.
Extruded polyethylene foam magnificent thermal insulation material, The scope of the insulation Applies. Tube Super polyethylene foam with closed cellular structure ideal for insulation of internal. One of the most popular insulation is styrofoam, popularly referred to as foam. It is used to improve thermal insulation of space, in other words, reduces the ability of the premises to give warmth. Properly executed installation allows you to reduce heat loss up to 30%. Therefore, heating costs can be reduced by the same number. In addition, during the summer heat it gives the room a severely overheated.
To correctly choose the styrofoam, you must know that he has different markings, and, consequently, the appointment. Basically you need to pay attention to the density specified by numbers. The density of the material also means its thickness in millimetres. The least dense is styrofoam, which is marking Figure 15. It is suitable for garages, utility and commercial premises. Styrofoam brand 25 possesses the necessary qualities for thermal insulation of facades of buildings. 35 mark is commonly used for thermal insulation of places where possible mechanical loads, for example, sex. The cost of the foam is directly proportional to its density: the denser, so more expensive. However, the denser material structure, the longer the lifespan of the entire system of thermal insulation.
Use foam as insulation has the following :
It keeps the heat, due to the low coefficient of thermal conductivity 0.03 -0.05 (for example, the coefficient of thermal conductivity of white sand-lime brick is 0.7 -0.8; red ceramic bricks-0.56);
has a small weight (weight of the foam material-structure, individual cells which filled the air; does not create structure loads);
relatively inexpensive (compared to other types of insulation);
the speed and ease of installation (easy to cut, that allows you to “circumvent corners and pick up the necessary form; do not require special tools and remedies;
not deformed when exposed to moisture.
subject to the rules of installation, serves several tens of years.
Cons of this material is also available:
When heated can allocate an unpleasant smell;
toxic when burning emits unpleasant smoke is harmful to human and animal health.
is the combustible material. However, when mounting, it is used as a layer between a non-combustible material, so by itself, additional fire danger does not create.
of material deficiencies, we can say that it is used primarily for external insulation. Can also be used for heat insulation of roofs.
For mounting of this type of heater does not need special knowledge. Only the required foam, glue, nails or screws, hammer or screwdriver. only one requirement-it must be level. Additionally, you can handle the special surface soil, a disincentive to fungi and microorganisms. Glue is applied in five points-four corners and Center, and then glued on the wall and secured with nails (screws). After performing the installation is carried out surfaces and exterior trim.
Everything you need to know when buying foam is required to mark and the finishing area. High demand for foam led to his production deal with numerous firms, including illegally. Naturally, that observance of the necessary technology, in this case, it is doubtful. You should be careful when you buy foam from little-known firms and in questionable places. You may also want to ask the seller of the existence of a relevant certificate.
