The backfill material for underfloor heating can be ceramsite or pisolite, both of which have certain advantages and disadvantages.
Ceramsite is a porous clay-based material. It is lightweight, has low water absorption, good air permeability, and is not prone to mold growth. Its use of backfill in the floor heating system can better promote the heat dissipation of the floor, conduct conduction and radiation more evenly, and improve the temperature stability and energy efficiency of the floor heating system. ground.
Pisolite is a natural granular mineral material with strong thermal inertia, which can maintain the heat of the underfloor heating system to a certain extent. Pisolite also has good drainage properties and is often used to improve soil structure and increaseenter the air permeability of the soil.
How much does it take to level 2.5 cubic pea stones for underfloor heating?
8 to 12. < /p>
Northern floor heating generally uses 8-12mm natural pisolite, because the surface of 8-12mm pisolite is smooth, without edges and corners, and the particle size is uniform.
Pisolite refers to a kind of modern-day building material. It is a stone the size of a soybean. It is generally used for floors and roofs. The particle size is similar to mung beans and is called stone powder in some places.
What is the difference between underfloor heating peach stone leveling and melon seed leveling?
The ratio of materials is 1:2: 3.
The material ratio of cement, pisolite and yellow sand in levelingof underfloor heating is 1:2:3. Because underfloor heating leveling is special, in addition to cement and yellow sand, it is also special. It is necessary to add certain spaces between the pea cores, which is more conducive to floor heating and heat dissipation.
Sanding or cracking is more likely to occur after leveling underfloor heating. Sanding is due to the insufficient strength of the concrete floor. Everyone should pay special attention to the dosage. The causes of cracks are multiple.
Pea stone is smooth and will not damage the floor heating pipe, but its price is relatively high.
1. The smooth button stone will not damage the floor heating pipe, but the price is relatively high. Pisolite concrete uses pisolite as underfloor heating backfill to protect underfloor heating coils. Natural silic contentium of pisolite gives underfloor heating better thermal conductivity. The price of floor heating leveling is as low as 50-80 yuan/㎡, while the most expensive price is 100 yuan/㎡ or even more.
2. Melon seed slices are cheap, but their irregular shape and sharp edges will scratch the heating pipes during the construction of the underfloor heating embankment and during their subsequent use. Over time, there will be hidden dangers of water leakage.
