Before buying polystyrene, we often visit various construction industry websites and numerous online forums for information about it. However, after a deeper analysis, the question arises, how to choose the best from a large number of proposals ?! What to consider when buying polystyrene? Is its quality, manufacturer, price important? Let’s try to find answers to these and other questions today.
When choosing expanded polystyrene, first of all, pay attention to:
- certification, marking and weight of expanded polystyrene plates;
- thermal conductivity coefficient (λ);
- quality of polystyrene (for example, equality of plates);
- recommendations for the use of polystyrene brands;
- reputation of the manufacturer;
- the price of polystyrene.
The polystyrene manufacturer must provide declarations of conformity and hygienic certificates for its products.
Before buying polystyrene, you should weigh the packaging of the foam to make sure that we get the right product of the appropriate density. The weight of polystyrene is an important indicator and directly affects the insulation and strength of the product. The higher the density of polystyrene, the heavier it is, which confirms its high technical parameters. If the polystyrene is lighter than stated by the manufacturer on the labeled packaging, it may mean a lower amount of raw materials and reduced quality of the insulation material.
Information on the density of polystyrene is not required by regulations and is not standard on the package. However, this indicator determines the quality of the product. Eurobud places density on packaging to ensure that its consumer buys quality, safe and durable polystyrene. Additional labeling not only makes it easier to choose the right polystyrene foam, but also gives everyone the opportunity to check whether the product meets the stated parameters.
An important criterion when choosing polystyrene boards is the thermal conductivity stated by the manufacturer (λD). The lower the ratio, the better and “warmer” polystyrene! Eurostroy recommends the use of lambda polystyrene not more than 0.040 W / mK for wall insulation.
For thermal insulation of facades we strongly recommend to use polyfoam with a density of 12,5-18 kg / m3 (EPS 60 – EPS 100), 15-25 cm thick.
For thermal insulation of floors on the ground, foundations, socles, flat and pitched roofs it is necessary to choose polyfoam with a density of 15-35 kg / m3 (EPS 80 – EPS 250), 15-35 cm thick.
The quality of polystyrene is a determining factor. When evaluating the quality of polystyrene, you should have basic information about the production process. Thanks to new modern equipment, direct supply of foreign raw materials and control system, Eurobud guarantees the perfect quality of each of our products.
Choosing the right brand of polystyrene for a particular application is very important.
One of the main factors of Eurobud’s openness and honesty is the placement on each package of readable information about the product parameters. They are presented in the form of a table showing the main properties, such as the minimum density of the product in kg / m³, compressive strength (CS), flexural strength (BS), tensile strength (TR) and the declared thermal conductivity indicated by the symbol λD.
Often, the main criterion when choosing insulation materials is the price of the product. However, in most cases, low-cost insulation materials do not meet the specifications on the package. Accordingly, in the future you will not get the desired result of energy savings and savings.
Eurobud, as one of the leaders in the production of expanded polystyrene in Ukraine, cherishes its reputation, invests in the development of production lines and the purchase of foreign raw materials, which in the future guarantees the final products of the highest quality.
