The difference between a master's roof and a non-human roof:
1. The engineering methods are different, the Venerable Master's roof is generally completed after the waterproof layer is completed, while the Venerable Master's roof has to be made after the waterproof layer is completed, and the floor layer is also made.
2. There must be a staircase leading to the roof floor on the roof, and a manhole can be left on the roof without a person to go up to the roof layer by climbing the ladder. The safety requirements for the roof are also different, and there can be no parapet wall on the roof without people.
There can also be a parapet wall, the height is not limited, and the roof of the Venerable generally has a parapet wall, and the height of the parapet wall is limited, and the height of the parapet must meet the safety requirements, generally not less than meters.
3. The function is different, the Venerable roof can be used for people to carry out activities on the roof, and the roof does not have this function.
Thermal insulation features
Insulation of flat roofs.
a.Insulation materials: lightweight, porous, and thermal conductivity should be chosen.
Small insulation. According to the characteristics of the finished product and the different construction technology of the insulation material, the insulation material can be divided into three types: bulk material, on-site pouring mixture and plate material. Bulk material and cast-in-place insulation have good plasticity and can also be used to replace slope finding layers.
a) Bulk insulation materials: mainly expanded perlite, expanded vermiculite, slag, etc. Because bulk materials are easily affected by wind and other factors during construction, it is not easy to form in place, and the construction is difficult, so it is less used in actual projects.
b) On-site pouring insulation material: It is an insulation layer made of bulk material as aggregate, mixed with cementing materials such as cement or lime and adding an appropriate amount of water, and poured on site. The processability of this insulation layer is better, but the insulation layer is still in a wet state after being in place, which is not good for heat preservation, and often needs to be provided with a vent in the heat preservation layer to dissipate moisture, and it is more troublesome in the structure.

When the house is decorated, it is generally made an insulation layer on the roof, so that in winter, the indoor temperature will not be too low, which ensures people's normal home, but it is also necessary to do the insulation layer correctly. So what is the practice of roof insulation, and what should be paid attention to in roof insulation, do you understand? Now let's take a look.
1. What is the practice of roof insulation?
1. Clean up the impurities and dust of the roof foundation; 2. According to the direction of the roof, measure the range of the thickness of the insulation layer; 3. The pipe roots in the structure need to be blocked tightly with fine stone concrete; 4. Evenly brush the air barrier layer, and the thickness should be moderate; 5. Lay the insulation layer and paste tiles on the insulation layer to enhance the appearance.
Second, what should be paid attention to in roof insulation?
1. When choosing insulation materials, you can use overall insulation materials or loose insulation materials, but the quality of insulation materials must be good, which will affect the effect of use. And under the insulation layer, you can use brush paint waterproof material to design an air barrier layer to make the insulation effect better.
2. Before brushing the air barrier layer on the roof, it is necessary to do a leveling process for the roof, and then wait until the roof is dry and then brush a cold bottom oil, so that the air barrier layer and the leveling layer can be better combined, and it is not easy to fall off the accident in the later stage. Then the insulation layer of the roof should be exhaust ducts and exhaust holes, and waterproofing.
3. When making the insulation layer, it is necessary to do the exhaust duct, which must be vertically and horizontally penetrated, and the spacing between the vertical and horizontal sides needs to be more than 6m at the end seam position and corner of the roof panel, and the groove width is designed to be 50mm to 70mm. For the exhaust hole, one needs to be set at 36 area.
What is the practice of roof insulation, and what should be paid attention to in roof insulation, it is introduced here first, do you understand? The roof insulation layer can make the living experience higher, but it is necessary to pay attention to the problems when making the insulation layer, so as not to affect the normal use in the later stage.

After the house is insulated, it can be more comfortable to live in, which can prevent the loss of indoor heat and air conditioning in summer. Insulation is called external insulation in the structure of the exterior wall, and internal insulation in the structure of the interior wall. So what is the practice of roof insulation?
1. First of all, the dust and dirt on the wall should be cleaned to ensure that it is clean, so that the insulation effect will be more prominent. Then, according to the slope of the wall and the direction of the flowing water, the thickness of the insulation layer is determined, and the relevant materials are prepared accordingly. Next, fix the pipe root of the threading structure and make preparations before construction.
2. If there is an air insulation layer, it should be painted, and it should be evenly painted, not too thick, and it needs to be leveled. Then you can start laying the insulation, which is bonded to the base layer of the roof, usually with cement and lime mortar. If you want to look aesthetically pleasing, you can also put some tiles on the surface for decoration.
What are the roofing insulation materials?
1. XPS extruded board.
The best of this material will be higher, its strength is super high, convenient for transportation, convenient construction, remarkable thermal insulation effect, but also waterproof and moisture-proof, with ultra-high stability and anti-corrosion performance, suitable for building roof insulation, building ground moisturizing, air conditioning ventilation ducts, etc.
2. EPS polystyrene board.
This material is the most affordable, its fire resistance and compressive resistance will be relatively poor, but its waterproof and moisture-proof performance is very prominent, can prevent corrosion, durable, mainly suitable for roof insulation, building walls, decoration carving of various models, waterproof layer of protective layer, etc.

According to the design requirements, the foam concrete is tested to determine the amount of cement, foaming agent, water, aggregate and admixture.
Clean up dust, debris and stagnant water from the base layer.
According to the design thickness and design slope of the foam concrete layer, the elevation (plastered cake) is pasted with cement mortar, and then the line is pulled and the reinforcement is punched. If there is no specified slope value in the design, the slope value should be 2%.
At the junction of the roof and the parapet and around the structure protruding from the roof, sub-lattice strips are buried.
Sprinkle water on the base layer to moisten it, and then apply a plain cement slurry.
Add foaming agent and water of 12 13 times the foaming dose to the foaming bottle and inflate and pressurize for 3 6 minutes, and stop the air compressor after the air pressure is boosted to the point of standby.
Add water and tensile fiber (according to the ingredients) in the mixer and stir for 1 2 minutes, then add cement and sand and admixtures in the mixer and stir for 2 3 minutes to form a thick thick liquid, and then add the foam formed in the above and stir. When the slump of the foam concrete in the mixer increases to 200 220mm, stop adding foam after reaching the design cubic weight ratio, and then continue to mix the foam concrete for 5 6 minutes. After that, the evenly mixed finished foam concrete is poured on the base bang.
The foam concrete is paved with a segmented flow operation, and the thickness of the virtual paving is multiple of the actual thickness, and then it can be scraped flat with an aluminum alloy scraper with a length of 3 meters.
When the foam concrete is close to the final setting, the lattice strips buried around the protruding part of the roof and the side of the parapet should be taken out first; After the final setting of the foam concrete, cut the lattice joints with cutting tools in time, the spacing of the lattice joints should be 3m 3m, the width of the lattice joints should be 25mm and the depth is the same as the thickness of the foam concrete laid, and the lattice joints should be filled with PVC high-grade sealing paste after the curing period is over.
Foam concrete should be watered and cured 24 hours after construction, and the curing time shall not be less than 14 days. During the curing period, try to avoid personnel walking on it and prohibit the accumulation of items, so as not to damage the bubble structure and affect the heat insulation effect.

With the improvement of the economic level, people's requirements for living conditions are getting higher and higher, especially for the cold winter in the northern region, people in order to make the indoor temperature meet the normal needs of life, in the construction of the house will use the insulation layer on the roof, so how to do the roof insulation? Which material is good for roof insulation? Let's find out!
How to do roof insulation:
1. Insulation material.
a. According to the characteristics of insulation materials and different construction techniques, it is divided into three types: bulk materials, on-site poured mixtures and plate materials. Bulk insulation materials are made of expanded perlite, vermiculite, slag, etc. Because these bulk materials are easily affected by other factors such as wind during construction, they are not easy to form and difficult to build, so they are rarely used in practice.
B. The on-site pouring insulation material is made of aggregate and cement, lime and other glued and stirred, and has good processability, but if it is constructed in a wet state, it is recommended to set up a vent in the insulation layer to dissipate moisture.
c. The plate material is made of benzene board, aerated concrete board, etc. This material is widely used, and the construction speed is fast, the insulation effect is good, and it is recommended that it is best to use more than two layers of plates to form an insulation layer during construction.
2. The position of the insulation layer.
A, the insulation layer is located between the structural layer and the waterproof layer is the most common practice at present, the insulation layer is located on the low temperature side of the roof system, not only the insulation effect is good and in line with the principle of stress, the structure is also simple. During construction, it is recommended to set up a vapor barrier layer under the insulation layer.
B, the insulation layer is set on the waterproof layer, this practice has special requirements for the insulation material, it is recommended to choose low moisture absorption, strong weather resistance of water-repellent materials, and on the insulation layer to add reinforced concrete, bricks and other heavier covering.
c. Combination of insulation layer and structural layer: although this insulation practice is rare, this practice can make the roof panel have the dual functions of structural layer and insulation layer at the same time, and can also reduce construction costs.
Which material is good to use for roof insulation:
1. XPS extruded board.
XPS extruded plastic board has high pressure resistance, good moisture resistance and good environmental performance. The texture is light and convenient for transportation and construction, and the thermal insulation effect is good, which is more used for roof insulation, ground moisturizing and other projects, but it is higher.
2. EPS polystyrene board.
EPS polystyrene board has good anti-corrosion performance, good thermal insulation effect, and is relatively cheap in terms of congqiao rent, but the compressive strength and fire resistance are poor, and it is mostly suitable for vehicles, ship refrigeration equipment and cold storage projects.
3. Expanded perlite blocks.
Expanded perlite blocks are non-toxic and tasteless, high compressive strength, non-perishable, general insulation effect, and high-quality, suitable for various wall roofing, swimming pools, cold storage and other thermal insulation projects.
4. Rock wool insulation board.
Rock wool insulation board has low **, high fire resistance, good thermal insulation and sound insulation effect, but its compressive strength is low, inconvenient construction, suitable for firewalls, elevator shafts and other projects.
Drivers are very prone to fatigue, the weather is fickle, the road conditions are unknown, and other factors are accident risks that cannot be ignored during the car owner's driving car, in order to help drivers better strengthen their own safety protection, it is necessary to buy a suitable driver insurance for themselves as soon as possible. Do drivers need to buy personal insurance accident insurance? >>>More
Because the drawing design must have building energy saving requirements, all roof insulation materials and thicknesses are generally clearly stated in the construction drawings, generally block-shaped insulation boards with a thickness of more than 50mm; In the illustrative atlas of architectural practices, there is only a statement that the thinnest part of the slope finding material is 40mm thick, such as cement perlite slope finding.
