Q:What is the difference between cement foamed thermal insulation board and thermal insulating brick?
Of course, the market now has a lot of insulation bricks, and some insulation bricks can only do external wall insulation, such as sand, aerated concrete blocks. Some also only do the interior wall insulation, such as gray aerated concrete blocks, and some insulation bricks directly to the base, thus omitting the internal and external insulation, such as concrete composite insulation block.
Q:What are the types of building blocks?
Ordinary housing: building brick (clay brick), and non sintered brick (sand lime brick, fly ash brick, cement brick, etc.)
Q:What is a JQK composite lightweight thermal insulation brick?
1. structural layer2. leveling layer3. waterproof layer4. thermal insulation layer and decorative layer
Q:What is the price of refractory bricks
The refractory insulating brick generally refers to light brick, normal furnace lining are using this brick kiln will not increase the weight, and good heat insulation effect and ordinary insulating brick production are made of clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating firebrick, diatomite insulating refractory brick, the use of light heat insulation brick can increase the use of the area, at the same time, good insulation effect, in the hot summer, the temperature of the furnace using solid clay brick and low 2-3 ~ C, reduce the power consumption. The construction is superior, the light insulating brick has good machinability, and the construction is convenient and simple, and the labor intensity can be reduced, the construction efficiency can be improved, and the construction period can be shortened. The price is determined by the choice of material and volume density, from several hundred to 5000 yuan, mainly with the choice of material
Q:Which kind of balcony heat preservation material is better?
New inorganic insulation material, this material thickness is thin, in 2-3 centimeters line, direct smear on the top of the house, without auxiliary materials, the price is higher than rock wool, aluminum silicate cotton.
Q:What is the price of thermal insulation brick for exterior wall?
Hello, the exterior wall insulation has many practices, useful insulation bricks, but also useful particles of polystyrene insulation mortar mixed (thickness is not the same, the price is not the same);
Q:What bricks are thermal insulation bricks?
Insulating bricks, a new type of product that can replace tiles, are mainly used in toilets, kitchens, TV sets, bedrooms, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
Q:How to do indoor thermal insulation
Basic decoration, can make indoor insulation work, such as some specific practices: when laid wood floor, the grille can be in the floor of the placement of insulation materials, such as mineral wool board, flame retardant foam etc.. In the custom doors, may require manufacturers with glass wool or mineral wool insulation materials etc.. To install windows and doors are sealed, if the window is the original single ordinary window glass, then the best decoration for hollow glass broken metal windows, can also use light decoration patent products: multifunctional solar heating refrigeration air conditioning doors and windows, doors and windows. Live in the top floor of the residents, but also in the ceiling when placed on the gypsum board insulation materials, in order to improve insulation. If the original wall has internal insulation layer, be careful not to destroy when decorating. If the design is to open the balcony and living room, it is necessary to install the insulation layer on the wall and top surface of the balcony.
Q:What material is good for indoor thermal insulation?
In the north, consider the polystyrene board system. You say polyurethane, Extrusion board, glass wool, aluminum silicate, are expensive, and the public construction is OK, and the use of housing is not very good.
Q:What is composite sintering insulation bricks?
The brick belongs to the porous brick and has good heat preservation performance. Reached the national 50%~65% energy efficiency standards. High safety (no crack, no seepage), strong durability (with building life), economy (self insulation, no need to increase the cost of insulation).
