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 uniformly, and improve the temperature stability and energy efficiency of the heating system. by the 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 structureand increase the air permeability of the soil.
What diameter of pebbles should be used for the installation of underfloor heating?
Approximately 0.9 cubic meters of pebbles. Usually, one square meter of underfloor heating backfill requires 0.015 cubic meters of pisolite, because one square meter of underfloor heating backfill requires cement, sand and pisolite, and the quantity ratio is 1: 2:3. Assuming the thickness of the embankment is 0.03 meters, the total volume is 0.03 cubic meters. The volume of each portion is 0.005 cubic meters, so we can calculate that pisolite is 3 times 0.005 equal to 0.015 cubic meters. Then multiply it by 60.
Is it better to use 4-8 or 8-12 pisolite for underfloor heating in the north?
Special pisolite For floor heating backfill, the required size is about 10mm, the surface is smooth, without edges and corners, only smooth, better conductivity.rmic, can better play the role of paving stone production base of Shandong Linyi, pisolite producer for floor heating, selects natural pisolite, secondary screening, 50 kg per bag, depending on the cement. , sand, pea stone ratio is 1:2:3 to complete. Say the important things three times, 10mm, 10mm, 10mm.
8 to 12.
Northern underfloor heating generally uses 8-12mm natural pisolite, because the surface of pisolite 8-12mm 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.
