Warm plasters for additional insulation at home
Life in a private home is often accompanied by a searchvarious solutions not just for cosmetic repairs, but also for increasing the thermal insulation properties of the walls of their homes, which in turn will increase the comfort of living and cut maintenance costs. And in this issue, modern building technologies offer several interesting options, among which very attractive look warm plasters.
Its catchy name is the building mix in fullit justifies, as it combines at once two components. Warm plaster, the price for which is quite a bit higher than the usual price, is a building mix and insulation at once. This effect is achieved due to its composition, which includes:
- an astringent mixture, which is a combination of gypsum, lime and cement;
- porous filler;
- polymer additives.
Fillers have the function of creating thermal insulation properties of the coating. Various materials can serve in their quality, but the most common are:
- Sawdust. On their basis, the cheapest mixture is obtained, but at the same time it is not very effective in comparison with the others.
- Styrofoam. This filler has excellent sound and heat insulation performance, but it is combustible, and its combustion is accompanied by the release of toxic substances.
- Perlite. This material is obtained from obsidian, also called volcanic glass. Due to the porous structure, it has good heat insulation (and therefore also warm plasters, in which it is used as a filler). But perlite has a significant disadvantage - hygroscopicity, i.e. the ability to absorb water vapor from the air. In view of this property, the use of additional materials for finishing is required to protect it.
- Vermiculite. It is also called foamed mica. According to its characteristics, this filler is similar to perlite. It is non-toxic and non-flammable. But its disadvantage is also hygroscopicity.
- Foam glass. It is a fireproof and waterproof material. It is distinguished by its high strength. But in terms of thermal insulation indicators, warm plasters on its basis are inferior to materials based on vermiculite and perlite.
- Easy to apply. There is no need for preliminary leveling of the wall surface. No need to lay reinforcing mesh, except for corners and cracks.
- Fast application. The procedure for its application to the wall is no different from working with conventional plaster.
- High adhesion. Warm plasters in this indicator show themselves well with all wall materials.
- Absence of cold bridges. This effect is achieved due to the lack of metal bonds.
- Impossibility of settling rodents in the walls.
There are many options where warm plaster can be applied. Feedback from homeowners suggests that it is effective for:
- internal additional insulation of the room;
- sealing seams, joints and cracks in the walls;
- finishing window and door slopes;
- Insulation of the plinth.
