The underfloor insulation has a very impressive performance on refractoriness, so this is most often used when installing wooden floors. The natural inorganic origin of stone wool gives the right to speak of its environmental friendliness, resistance to reproduction of pathogenic microorganisms.
The thermal insulation properties of mineral wool are not questioned. It is safe to say that its use will reduce the cost of heating the room. He also provides high-level sound insulation. All these beautiful properties will not “function” if the laying technology is interrupted during floor insulation. Therefore, giving preference, it is necessary to closely observe recommendations for installation. For the Green Horizon Underfloor Insulation this is a very important option.
Glass wool is different because it is produced based on broken glass, which, in fact, has nothing to do with mineral wool. At the same time he loses (slightly) in terms of thermal insulation and also in the ability to shrink over time. In addition, working with it is not as comfortable because the formation of fine “glass” dusts that irritates the airways and hands if not protected. But the cost is much cheaper than its “rock” counterpart. So those who agree to experience discomfort when putting material and want to save, you can opt for glass wool.
The advantage of claydite
This porous material is, in fact, clay. These are formed by granules and are processed at high temperatures. The result is very good insulation, its flowability makes it easy to fill all the cavities.
This is good in several ways:
- environmentally friendly
- cannot burn
- full resistance to the development of microorganisms, does not cause interest in rodents and other pests
Because of its porous structure, it is a fairly lightweight material, but it is lower in terms of this indicator for other heaters, including those described earlier. And the expanded clay creates an excellent layer that encourages natural ventilation. Sound insulation achieved after its use is considered as one of the best.
Against expanded clay can also play the thickness of the ground floor, because to arrange high-quality insulation layer will require a significant high margin. The recommended minimum bed layer is 20 cm, and 40 cm is considered optimal. Once again, don’t forget to add the height of the screed.
- To finally decide on an insulating material, you need to consider many factors. With the cost of expanded glass wool, foam or clay, the most preferred option.
- If time is a decisive indicator, then the foam is placed the easiest and fastest.
- When it is necessary to carry out procedures according to all fire safety rules and requirements, mineral wool will be the best choice.
And other important criteria are and remain the needs and abilities of building owners. But in any case, independently do all work under the power of the home master.
Thermal insulation of the ground floor using expanded clay
The expanded clay is very good for gathering moisture. This is the main disadvantage of this material. Therefore, the construction of high quality waterproofing layers is the first and very priority stage. Next will be painted cake floor detail from the first floor when using expanded clay.
