Foam glass what is it and why do I need to

Foam glass what is it and why do I need to In the category Spray foam insulation 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 Foam glass what is it and why do I need to.

How and why to insulate walls, Foam glass and foam Isol, Why should I insulate walls and how can this be done? No matter how it sounded. As it is for us a new material on the forums you can find a lot of questions that very few answers. We will try to understand the main characteristics of foam glass, compare it with the closest analogues, and consider. In what case to buy it, and it costs quite a lot, and when you can easily get by cheaper and more familiar counterparts.

Foam glass in the form of pellets versus ceramic concretes

To begin, compare foam glass with ceramic concretes. Foam glass use much cheaper than expanded clay, only in some cases, for example, if you want to insulate the roof. So, in order to reduce the thermal conductivity of your roof will need different amounts of these two materials, since the thermal conductivity of expanded clay -1.18 0.1 w/m * k, and foam glass-0.06 -0.07, i.e. almost twice lower. Therefore, to achieve the same efficiency, foam will need less, but still because of its prices it will cost more.

Next, you have to pay attention to this shortcoming, as clay water absorption, which is up 24%, i.e. If the roof is leaking, then claydite will absorb in itself significantly and moisture, so it is necessary to strengthen the walls and foundations, especially considering that expanded clay itself is heavier than foam glass. Water absorption of the latter is only 2-4%, while its small weight, even at the maximum moisture does not make negative influence on the home, which means you will save and the Foundation, and on the walls, and the savings will be much greater than the savings when choosing insulation.

In the example above, the use of foam glass and rightly so, but in each case you must map the properties of the two materials with operating conditions. For example, if you insulate overlap, of course, it is better to choose expanded clay, because the chances of getting wet, and there is no material cheaper.

Sheet foamglass versus penosterolom

Similar examples can be cited for foam glass in sheets, the closest analogue that is styrofoam. So, if you compare the characteristics, it can be concluded that foam glass more expensive and not always met expectations, its density is several times more, which means it is harder, the coefficient of thermal conductivity, even a little more than foam, water absorption is the same but the price once in 5-6 above. If you insulate walls in a typical House, where Interior and exterior finishes are used the most usual materials, which certainly does not exceed 50 years, then choose really better foam.

Foam glass what is it and why do I need to

The advantage of foam glass in this case is that it can last 100 years or more, so if you use expensive and durable finish, the type of marble or granite, which hold over the centuries, the foam just gone inside walls through 40-50 years, and will not perform their functions, but with the cellular glass would be fine, so in this case it is worth to spend money on this heater.

Pay attention to the fact that styrofoam works well in rooms with a temperature of +80 degrees: again, if this is a common living room, it is quite correct, but Rudas foam glass-great option, because nothing will be with him even at 450 degrees. Other ways of warming saunas frequently is also inappropriate: Rockwool accumulate moisture, foam when burning emits hydrocyanic acid, so in General is not valid in the circumstances. That is why the premises of this kind can be used, though not the cheapest, but reliable material is glass. Therefore, the scope of expensive foam glass-where other options for whatever reason are not suitable.

It is worth noting that the glass is completely healthy stuff, because in the process of operation does not emit any harmful substances. Foam, unfortunately, can slowly allocate styrene, gradually poisoning the residents, but our mentality is based on yet that what does not kill us all at once, is considered quite safe. In this context, it makes sense to spend money, unless, of course, there are the means to a more eco-friendly material.

Block foam glass in comparison with aerated concrete

But that’s not all, because the glass can be used for the manufacture of blocks, the type of concrete used for capital construction. It is with this material and will be compared. It is worth mentioning the price immediately, as even the imported gas will cost you 4 times cheaper than domestic unit.

For these two materials only indicator of durability is roughly the same-more than 100 years. Further foam glass for all options makes use of aerated concrete: it two times lighter, while a higher compression strength, and it is two times lower thermal conductivity. But the most important thing is that the water remains at the level of 3%, whereas gas and can absorb up to 30% moisture, and it is hardly its main shortcoming.

As a rule, such a disadvantage of aerated concrete in normal residential construction is neglected, because this index. But all the same, but exceptions occur mainly with individual important buildings. For example, the dome of Novosibirsk Opera House, made of aerated concrete, so was saturated with moisture that became incredibly heavy, , lost all of its insulating properties, and the building is now in disrepair. Easy way out-or in this case, do not use this type of material, either replace the aerated concrete cellular glass. As you can see, and in this case, the glass is only used.

When analogues completely inapplicable

Because of its high prices not so extended to glass construction market, and some did not even have heard of it, although it ahead of many properties. But in some cases even pay such a high price is justified, because it sometimes requires material with clearly defined properties, and if we take into account any additional costs resulting from the use of traditional materials, it can be concluded that often even more economical glass. Now it is most commonly used in the construction of baths, basins, domes and roofs.
