What materials are used for thermal insulation of the floor on joists
Beam floor is not particularly popular among apartment owners. But in private homes, they are still found in many cases. Due to the fact that a free space remains between the beams, can be laid still and a layer of insulation, which will make the design more practical. But what insulation is best to use?
1. Mineral wool floor on joists
Simple mineral wool characterized by excellent thermal and sound insulation characteristics. Thus, it has ecological purity and easily pass air. But her problem is the low humidity. Therefore, prior to bookmarks between joists need to carry out a vapor barrier. Otherwise damp evaporation from the ground floor or basement of spoil material. Also, the top must be covered with waterproofing mineral wool to accidentally spilled liquids do not hurt the material.
2. Extruded styrofoam for floor on joists
Expanded polystyrene in the form of slabs is less whimsical insulation than mineral wool. It can be laid without creating additional steam and waterproofing layer. But with both materials it is important not to leave any gaps, spaces or gaps. That is, mineral wool and expanded polystyrene are placed between the joists maximize tight.
3. Expanded clay floor warming on joists
This insulation is most often used owners, which is important to have at the same time secure, fire-resistant and moisture-resistant insulation. Indeed, the expanded clay is not afraid of a variety of negative impacts, and endowed with excellent insulating performance. In this case, most importantly, that the heat insulating layer bombarded thickness not less than 8 cm. Otherwise, get a good seal will fail. Again, in the steam and waterproofing concrete block does not need.
4. Granulated polystyrene for insulation of floor
Finally, engaging the thermally insulating material is also in the form of polystyrene beads. Material according to their characteristics and principles of application like a concrete block. But he is not so reliable, so if there is mechanical stress granular polystyrene directly deformed and does not lose the original insulation performance. Another drawback of the material may be called its flammability. But in extreme cases it can be used for filling between the floor joists.
Presented thermal insulation, in principle, reveal themselves very worthy. The main thing - to use them properly.
